Description of Research Trial: To evaluate (study) the safety and effectiveness of the MitraClip System (“Study Device”) in patients with of mitral regurgitation (MR) that are at high risk for mitral valve surgery. The Study Device consists of an implantable clip to repair the mitral valve and a delivery catheter (a thin, flexible tube through which the clip is passed into the body). The Study Device has not been approved by the US Food and Drug Administration (FDA) for use outside of research trials, and is considered experimental in this study. Participant Requirements: The COAPT Trial is recruiting individuals who have moderate-to-severe or severe functional mitral regurgitation (FMR) and have been determined to be at high risk for traditional mitral valve surgery. FMR occurs when the two leaflets of the mitral valve do not close properly, causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward. This is a randomized study which means that there is a 50/50 chance (like flipping a coin) of being assigned to receive the study device or not. Subjects assigned to the Control (no Device group) may be eligible to receive the Study Device after their two year study visit. Up to 420 patients at 75 medical centers in North America will participate in this clinical study. We hope to enroll up to 20 participants here at Northwestern. Participation in the study will last up to five years.

The BEST-CLI study This study is recruiting participants diagnosed with peripheral artery disease (PAD) that has led to critical limb ischemia (CLI). In CLI, arteries that deliver blood to the leg and foot are narrowed or blocked by plaque buildup (atherosclerosis). CLI can cause pain in the foot or leg even when sitting or lying at rest; it also can cause foot and leg ulcerations, and can sometimes lead to gangrene and loss of the leg. CLI is usually treated by operations or procedures that increase blood flow to the leg and foot, in order to relieve these symptoms, heal the ulcers, and preserve the limb. There are two different ways to increase the blood flow in CLI. One is with open surgery, which creates a bypass around the blockage. The other is with endovascular treatment (often called angioplasty), a minimally invasive procedure that opens the blocked arteries directly. Angioplasty is performed with balloons and other tools that clear plaque, and sometimes permanent implantation of small, mesh-like metal tubes called “stents”. Both types of treatment – open surgery and angioplasty - are considered reasonable and appropriate for patients with CLI. Half of the participants in this study will have open surgery and half will have endovascular treatment. The assignment of treatment is random, meaning purely by chance (50:50, just like a coin toss). The purpose of the study is to learn about which therapy is more suitable for those patients who are candidates for both open surgery and endovascular treatment, and to provide information regarding cost effectiveness of the two different types of treatment. We expect 2100 participants to enroll from approximately 120 different study centers across the United States, Canada, and possibly other countries. We hope to enroll up to 20 participants at Northwestern.

Carotid revascularization for primary prevention of stroke (CREST-2) is a multicenter, randomized controlled trials of carotid revascularization and intensive medical management versus medical management alone in patients with asymptomatic high-grade carotid stenosis. One trial will randomize patients in a 1:1 ratio to endarterectomy versus no endarterectomy and another will randomize patients in a 1:1 ratio to carotid stenting with embolic protection versus no stenting. Medical management will be uniform for all randomized treatment groups and will be centrally directed.

Congestive heart failure often results in shortness of breath or fatigue with exertion. Medical treatment for this problem usually consists of medications such as Lisinopril (also called ACE inhibitors or ARBs) and Lopressor (also called beta blockers). It is believed that a fixed dose combination of Isosorbide Dinitrate and Hydralazine (FDC I/H) works better in African Americans with heart failure when compared to their white counterparts. Despite the possible benefits, the drug is prescribed in only 25% of African Americans. It is believed that the positive response to this drug may be a difference in the genetic make-up of African Americans. “DNA”, “gene”, or “genetic make-up” is inherited information (a blueprint) about the structure and function of cells in the human body that make up the color of our hair and eyes and may influence the way our bodies respond to certain stimuli such as smoking, an illness, or infections. FDC I/H is FDA (Food and Drug Administration) approved for self-designated African Americans with heart failure. The goal of the current study is to see if a genetic blood test would indicate who within the African American group would show a positive response to the study medication. We are asking 500 self-designated African Americans who are 18 years old and older with congestive heart failure to participate. Up to 50 subjects will be asked to participate at Northwestern; the study duration is approximately 24 months.

The purpose of this study is to see if acupuncture after heart surgery can prevent onset of atrial fibrillation (AF) and reduce pain, nausea and symptoms of depression. AF is an irregular heartbeat, which may cause symptoms such as pounding sensations in the chest, dizziness, fatigue, chest pain and/or shortness of breath and can cause blood clots to form in the heart. AF is one of the most common complications to occur after heart surgery. Acupuncture involves the insertion of extremely thin needles through the skin at strategic points on the body. Acupuncture has been used in traditional Chinese medicine for thousands of years for a variety of illnesses and has been shown to be effective for the treatment of nausea and vomiting in adults following surgery. Acupuncture seeks to release the flow of the body's vital energy or "chi" by stimulating points along 14 energy pathways. Scientists say the needles cause the body to release endorphins -- natural painkillers -- and may boost blood flow and change brain activity.

SCOUT: This study is looking for patients who have a “leaky” tricuspid valve in the heart. The leakage of blood is also called regurgitation. The tricuspid valve is located within the right side of the heart. This condition is referred to as functional tricuspid regurgitation (FTR). FTR occurs when the valve itself has been determined to be normal. However, the heart is enlarged and pulls the valve open more than it should be. As the heart works hard to pump blood throughout the body, the leaking valve allows blood to flow backwards in the wrong direction, and therefore the heart cannot pump enough blood through the body. The symptoms that patients may experience are an irregular heartbeat, fatigue, a fluttering discomfort in the neck, right abdominal pain, shortness of breath, swelling in the legs or abdomen, and cold skin. The purpose of the SCOUT study is to learn initial information about the basic safety and function of a new investigational device, the Mitralign system. The Mitralign system is a tricuspid valve repair device which uses catheters placed through two small openings in a vein in the neck to deliver surgical sutures (threads) through the ring (annulus) around the tricuspid valve. These sutures are then pulled together (as is done with threads when sewing) to make the tricuspid valve opening smaller and reduce regurgitation. These sutures are then locked in place with a small stainless steel lock. Implanting this device does not require open-heart surgery. The study valve is an investigational device meaning it has not yet been approved by the US Food and Drug Administration (FDA). This research study plans to enroll approximately 15 study participants at up to 5 sites in the US. We are looking to enroll up to 8 people at Northwestern.

CLR325X2202: The purpose of the study is to determine if an investigational drug called CLR325 (“the study drug”) is safe and tolerable in heart failure patients. “Investigational” means the study drug has not been approved the FDA for the treatment of people with heart failure. The study drug is currently not “on the market” (available for prescription for and/or to buy) in any country. This is the first time it will be studied in patients with heart failure. Participants will receive a single infusion of either the study drug or a single infusion of placebo. A placebo is a dummy drug with no active medicine inside and is used to make sure that the changes reported are not just happening by chance. The placebo used will be a saline (salt water) solution. Study participation will last for about 1 month. During this time participants will be asked to come to the hospital once and the outpatient clinic 3 times. We expect to enroll up to 8 people here out of 40 people in the entire study nationally.
Inclusion Criteria: 1) Male and female patients >18 years of age. 2) Patients with a cardiac ejection fraction of ≤45% assessed within the last 6 months. 3) Patients who are planned to have a clinically indicated pulmonary artery catheter in place prior to randomization. EXCLUSION CRITERIA: 1) Patient with known significant valvular heart disease including severe aortic stenosis or severe mitral stenosis 2) Patients admitted to an inpatient setting for acute decompensated heart failure within the last 30 days. 3) Patients who have received an intravenous infusion of a cardiac inotrope (e.g., dobutamine or milrinone) in the last 24 hours prior to randomization.

KNO3CK-OUT HFpEF: This study is enrolling participants with a diagnosis of heart failure with preserved ejection fraction (HFpEF). This is a condition that causes patients to be short of breath and limited in what they can do in their daily lives. Currently, there are no approved drugs for this condition. Researchers are trying to find new therapies for this condition. The purpose of this study is to test whether Potassium Nitrate (KNO3) will improve how people with HFpEF can exercise. In HFpEF, patients are limited in their ability to do all the things they want to do, and exercise as much as they would like, due to becoming tired and short of breath early. We do not know exactly why these limitations occur. There is some evidence that in addition to problems with the heart, patients with HFpEF also have problems with their arteries and muscles that affect their ability to exercise. Potassium Nitrate has been shown to improve how muscles work and also improve blood flow to working muscles in the body in healthy individuals. We previously conducted a pilot study with our KNO3 pills and found them to be safe in subjects with HFpEF. We would like to now study our pills in a large study to see if we can improve exercise in HFpEF. The use of Potassium Nitrate in this study is investigational. Potassium Nitrate has not been approved by the Food and Drug Administration (FDA) for the use being evaluated in this study.

The purpose of this research study is to determine if a new investigational device, Thoraflex Hybrid, is safe and effective for the surgical treatment of damage or disease of the aorta. The aorta is the main artery that takes blood away from the heart and runs through the chest and abdomen. The damage or disease may be due to either a bulge or ballooning in the wall of the aorta (called an aneurysm) or a tear in the wall of the aorta (called a dissection). The Thoraflex Hybrid device is used to treat both aneurysm and dissection of the aorta in the chest. Surgery for aneurysm/dissection involves replacing the weakened section of the vessel with an artificial tube, called a graft. This may be done by either, cutting out the weakened area and replacing with a graft, or by placing a graft inside the weakened blood vessel to act as a lining. The study device combines both these types of procedure in a single device. The Thoraflex Hybrid device has been licensed in Europe since 2012, but is not yet approved by the U.S. Food and Drug Administration (FDA). As the device is not yet approved by the FDA it is classed as an “Investigational” Device. This study will involve about 65-80 people at about 14 different centers in the United States. We hope to enroll up to 10 patients at Northwestern.

This research study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) Model 9600TFX and associated delivery systems in patients with symptomatic, severe, calcific aortic stenosis who are at low operative risk for standard aortic valve replacement (AVR). Low operative risk means that patients may have less than a 2% chance of death 30 days after open-heart surgery. The delivery system is the Commander system, which uses transfemoral access (through a blood vessel in the leg) to place the valve in the heart. Patients agreeing to participate in this investigational (experimental) study will have a 50/50 chance of receiving the study device or surgical aortic valve replacement (SAVR). Participation in this research study will last approximately 10 years. Participants will be asked to come to clinic for study visits at 30 days, 6 months, and 12 months after the study procedure and then annually until 10 years after the procedure. We expect no more than 120 people will be enrolled at Northwestern The study expects to enroll up to 1228 people at up to 50 sites nationally

INOvation-1: This study is enrolling participants with pulmonary arterial hypertension (PAH) that are currently taking at least 1 PAH drug treatment approved by the Food and Drug Administration (FDA). The drug being studied is “inhaled nitric oxide” and the device being studied is called the “INOpulse.” Inhaled nitric oxide is a drug approved by the FDA and Health Canada for the treatment of infants who have difficulty breathing and have decreased oxygen in their blood associated with pulmonary hypertension. However, inhaled nitric oxide, in combination with the INOpulse delivery device, is an investigational treatment of PAH and is not currently approved by the FDA or Health Canada. “Investigational” means that the drug-and-device combination tested in this study has not been approved by the FDA or any other health authority. The purpose of this study is to determine if inhaled nitric oxide (study drug), when given and breathed through the INOpulse (investigational device), may help treat PAH.

CV002-004: Heart failure is the number one reason for hospitalizations in elderly adults in the US. Acute decompensated heart failure (ADHF) occurs when heart failure symptoms suddenly become worse, including difficult breathing, swollen legs and feet, and fatigue. 30-50% of patients hospitalized for ADHF die or are re-hospitalized for heart failure within 6 months post discharge. Therefore, new treatment options are needed for these patients. Biomarkers are measured indicators of disease and play an important role in the discovery and development of new drugs, e.g. to treat heart failure. The purpose of this study is to gain further understanding of blood and imaging biomarkers (imaging biomarker is a feature or characteristic detectable in an image, such as a thickening of the heart wall) in different heart failure populations (stable or acutely decompensated) and to compare to subjects without heart failure. There are no experimental drugs in this study. All patients will be on standard of care treatment for heart failure. However, participants will receive an approved gadolinium-based contrast agent, called gadobutrol (Gadavist®, Gadovist®), as part of the MRI procedure. MRI contrast will be given two times during the study; Day 1 and Week 24. We expect that participants will be in this research study for 1 year, which includes 3 to 4 clinical visits over 24 weeks (6 months) and a follow up phone visit at 1 year.

This study is recruiting individuals that are scheduled to have Boston Scientific’s S-ICD System implanted to manage a heart condition, when it is programmed with specific settings. Since the entire device system is already approved by local regulatory authorities, there is nothing investigational about either the device system or the implant procedure. Specific device settings available in the approved device will be tested. The S-ICD System will be programmed to detect only very fast ventricular heart rhythms that are considered life threatening. This should allow participants to avoid receiving a shock from their device for fast heart rates that do not require a shock to terminate, and to avoid shocks that are considered inappropriate (fast signals that are not originating in the ventricle, but the device would wrongly classify as ventricular arrhythmia and deliver a shock). The follow-up visits and information collected during the conduct of the study are typical and routinely done a physician. This study provides Boston Scientific CRM with additional data about the long-term performance of the implanted device system and the optimal way to program the device to allow avoiding unnecessary and uncomfortable shocks. We expect that participants will be in this research study for up to 18 months after their S-ICD implant procedure. Participants will not need to attend any extra clinic visits for the study. Information will be recorded before and during the S-ICD implant procedure, at the time of discharge from the hospital, and thereafter during regular 6-month, 12-month, and 18-month follow-up visits that are part of standard care after an implant procedure. Approximately 1,100 participants will be enrolled in the study at up to 200 sites worldwide. We expect up to 20 people will take part here at Northwestern.

Aspirin Dosing: A Patient-Centric Trial Assessing Benefits and Long-term Effectiveness (ADAPTABLE). The goal of ADAPTABLE is to try to find out which dose of aspirin is better for subjects who have heart disease. Subjects who join this study will take either low-dose or regular aspirin every day. That way, we can learn which is better in terms of reducing the risk of heart attacks, strokes, bleeding, and death. We expect up to 15,000 subjects with heart disease from across the U.S. will take part in ADAPTABLE.

One routine testing uses echocardiography (ultrasound of the heart) to create heart images and make measurements while gradually increasing the LVAD heart pump speed. Each time the pump speed is increased, images and measurements are taken. This is called a ramp test. The ramp testing may also be performed during a right heart catheterization procedure (insertion of a catheter into a vein or artery in the groin, arm or neck guided to the heart using X-ray imaging). Doctors normally perform this procedure to obtain hemodynamic measurements (measure the pressure and blood flow in the heart). If the ramp testing is performed during this procedure, then the doctors have additional measurements to consider before choosing a final speed for the LVAD pump. Both of these methods for determining pump speed are accepted as normal, routine care for LVAD patients. In this study participants will be randomly (by chance) assigned (1:1) evenly to one of these two methods of testing. The main purpose of this study is to compare Echo-guided testing to the Hemodynamic-Echo Ramp Tests to determine which method of testing provides better information for adjusting pump speed and medical treatment for LVAD patients. Better adjustments may provide better quality of life, exercise tolerance and reduced unwanted cardiac events over a 6-month period.

Early Feasibility Study of the CardiAQ-Edwards™ Transcatheter Mitral Valve (TMV) System For the Treatment of Moderate to Severe Mitral Regurgitation
This study is enrolling patients with moderate to severe mitral regurgitation who are considered to have a high risk for traditional open-heart surger…
This study is enrolling patients with moderate to severe mitral regurgitation who are considered to have a high risk for traditional open-heart surgery. Mitral regurgitation, MR, is a condition in which blood flow through the mitral valve flows in the wrong direction during part of the cardiac cycle, which negatively affects the blood flow to the rest of the body. The purpose of this study is to find out if the mitral valve can be safely replaced using a procedure that is simpler than traditional open-heart procedure and may be safer for patients who are at a higher risk from open-heart surgery. The new device is called the CardiAQ™ Transcatheter Mitral Valve Implantation (TMVI) System (Transseptal and Transapical Delivery Systems). The CardiAQ™ TMVI system is experimental and is not yet approved by the U.S. Food and Drug Administration (FDA) for sale in the United States. This device is implanted without the need for an open-heart procedure and without the need for a heart and lung machine. It is implanted using a delivery catheter, which is a long tube with the valve attached at one end and a handle attached at the other end to control the placement of the valve. The long tube will be inserted through an incision inside the left or right groin (transseptal) or through an incision in the chest between the ribs (transapical). The standard medical treatments generally available to patients with mitral regurgitation who do not undergo surgery may temporarily alleviate some symptoms, but will not permanently alleviate the condition or cure mitral regurgitation. Participation in this study will last for approximately 5 years. Participants will be expected to attend a minimum of 8 scheduled study visits after discharge from the hospital at 1, 3, 6, 12, 24, 36, 48 and 60 months after the procedure.
Patients with moderate to severe mitral regurgitation who are considered to have a high risk for traditional open-heart surgery. General Criteria:
1. Greater than or equal to 18 years of age.
2. New York Heart Associate Classification ≥ II
3. Left Ventricular Ejection Fraction ≥ 30%.
4. Mitral regurgitation (MR) ≥ Grade 3+ (moderate/severe, or severe) where EROA ≥ 0.30 cm2 or VC width ˃ 0.7 cm.
5. Patient is determined to be high surgical risk but operable as assessed by the site’s ‘Heart Team’ (a minimum of one Cardiac Surgeon and one Interventional Cardiologist). Inclusion of a heart failure specialist is strongly recommended.

The purpose of this study is to find out if a drug called dapagliflozin would be effective in improving the blood tests and symptoms related to heart failure while also treating type 2 diabetes. To do this, dapagliflozin will be compared with placebo. The placebo will look like dapagliflozin but is inactive. Dapagliflozin lowers glucose (sugar) levels in the blood by blocking the effect of specific molecules (small particles) called sodium-glucose transporters. Under normal circumstances, the sodium-glucose transporters in the kidney prevent glucose in the blood stream from leaving the body through urine. Dapagliflozin inhibits the sodium-glucose transporters and lowers blood glucose by allowing glucose removal through the urine. Dapagliflozin may also mildly decrease body weight and lower blood pressure in certain patients. Dapagliflozin is approved by the United States Food and Drug Administration (FDA) for the treatment of type 2 diabetes. Dapagliflozin is not specifically approved for the treatment of type 2 diabetes in people with heart failure and therefore its use in this study is investigational. We expect up to 20 people here will be in this research study out of 250 people in the entire study nationally.

Patients with Atrial Fibrilation (AF) can have a fast and irregular heart rate which can cause fainting, chest pain, shortness of breath and other symptoms. This study is enrolling participants that are scheduled to undergo an electrophysiologic (EP) procedure to treat AF. This procedure looks at the heart’s electrical activity to find the area in the heart muscle that causes the heart rate to increase. It is not easy to find the site that causes AF. Therefore, multiple sites on the heart may have to be scarred (ablated). This is done to stop the fast heartbeats from spreading to other parts of the heart. The purpose of this research is to compare this standard ablation procedure to FIRM (Focal Impulse and Rotor Modulation) guided procedure. The FIRM procedure uses software and probes to find the sites of AF. Both the standard ablation and FIRM guided ablation are approved by the US Food and Drug Administration to treat arrhythmias (irregular heartbeats). We expect up to 15 people at Northwestern will be in this research study out of 268 people in the entire study internationally.

This research study is recruiting patients who have one of the following conditions: 1. A bulge in your aortic wall (aneurysm) caused by weakening in the aortic wall. Over time, this bulge may continue to grow larger and could rupture. 2. A tear in your aortic wall (dissection). Blood flows through this tear, causing the layers of the aortic wall to separate (dissect) and create a new channel for blood flow. This channel may continue to grow and could rupture. 3. Bleeding and blood clots within your aortic wall (intramural hematoma). This can lead to weakening of the aortic wall and aortic rupture. 4. A lesion (wound) or ulcer in your aortic wall caused by aortic disease and can progress and lead to an aortic aneurysm, dissection, or rupture. 5. A traumatic injury to your aorta that can result in a tear, lesion, or rupture of the aortic wall. The aorta is the main artery in the human body that carries oxygenated blood to all parts of the body. Disease of or injury to the aorta can be a life threatening condition The study will look at treating these aortic diseases and injuries with a new medical device called the GORE® TAG® Thoracic Branch Endoprosthesis (TBE Device). Depending on the location of your aortic disease or injury, the study device will be implanted inside your aorta and one of the main arteries that branches off your aorta supply blood to the brain and arms. Study participants will be expected to return for follow-up visits with the Study Doctor at one (1), six (6), 12, 24, 36, 48, and 60 months following the procedure.

This study is recruiting patients who have an acute (very sudden onset or rapid change, within 2 weeks), complicated type B aortic dissection. One way to repair an acute, complicated type B aortic dissection is with an endovascular stent-graft. A stent-graft is a polyester fabric tube (graft) sewn onto metal springs (stent). The stent-graft is compressed inside a narrow plastic tube called a delivery system, which is inserted into the blood vessels in the groin area (femoral/iliac artery) and then threaded through the blood vessels to be placed at the area of the dissection inside the aorta. This research study will assess and evaluate safety and performance of an endovascular stent graft called the RelayPro Thoracic Stent-Graft System (the “Study Device”). The Study Device is investigational, which means it is still being tested and is not approved by the Food and Drug Administration (FDA) for sale in the United States. We expect that participants will be in this research study for approximately 5 years after their endovascular repair procedure. Participants will return to clinic at 1-month, 6-months, and 1-year, and then annually out to 5 years. These visits are considered part of standard care, and the results of test done at these visits will be recorded for the study. We expect up to 5 people here will be in this research study out of 80 people in the entire study nationally.
Inclusion Criteria:
Subject must have an acute (symptom onset to diagnosis within 2 weeks)or subacute, complicated type B aortic dissection (entire dissection is distal to the left subclavian artery (LSA)), confirmed by Computed Tomography Angiography (CTA) or Magnetic Resonance Angiogram (MRA), with time from symptom onset to diagnosis ≤ 6 weeks, with at least one of the following:
- Malperfusion of the viscera, kidneys, spinal cord, or lower extremities, measured by clinical or radiographic evidence;
- Rupture;
- Intractable pain.
Proximal and distal aortic neck with diameter between 19 mm and 42 mm.
Subject's anatomy must meet all of the following anatomical criteria:
a. Proximal attachment zone distal to the left common carotid and a distal attachment zone proximal to the origin of the celiac artery.
i. Dissection is permitted in the distal attachment zone but is not permitted in the proximal attachment zone.
b. The length of the attachment zones will depend on the intended stent-graft diameter and type of graft selected.
c. The proximal attachment zone should be: i. 15 mm for 22 - 28 mm RelayPro grafts with bare stent (20 mm for RelayPro grafts with non-bare stent). ii. 20 mm for 30 - 46 mm RelayPro grafts with bare stent (25 mm for RelayPro grafts with non-bare stent). iii. Proximal to non-dissected segment (healthy zone). d. The distal attachment zone should be 20 mm for all RelayPro grafts. e. Coverage of the left subclavian artery is permitted with mandatory revascularization if patent left internal mammary artery (LIMA) bypass or left upper extremity (LUE) arteriovenous graft or anomalous vertebral artery off the aorta. Revascularization must be performed prior to device placement, and may occur during implant procedure, provided it is before coverage of the LSA by the endograft.
5. Proximal attachment zone containing a straight segment (non-tapered, non-reverse-tapered, defined by <10% diameter change) with lengths equal to or greater than the required attachment length for the intended device.
6. Vascular dimensions (e.g., aortic diameters, length from left subclavian to celiac artery) must be in the range that can be safely treated with the RelayPro Thoracic Stent-Grafts.
7. Adequate iliac or femoral artery access for introduction of the RelayPro Delivery System. Alternative methods to gain proper access may be utilized (e.g., iliac conduit).
8. Subject willing to comply with the follow-up evaluation schedule. 9. Subject (or Legally Authorized Representative, LAR) agrees to sign an Informed Consent Form prior to treatment.

Exclusion Criteria:
Subjects will be excluded from the study if any of the following apply:
Diagnosis of traumatic injury or transection of the descending thoracic aorta.
Significant stenosis, calcification, thrombus, or tortuosity of intended fixation sites that would compromise fixation or seal of the device.
Planned coverage of left carotid or celiac arteries; or anatomic variants that would compromise circulation to the carotid, vertebral, or innominate arteries after device placement, which is not amenable to subclavian revascularization.
Prior endovascular or surgical repair in the descending thoracic aorta. The device may not be placed within any prior endovascular or surgical graft.
Concomitant aneurysm/disease of the ascending aorta, aortic arch, or abdominal aorta, requiring repair. Dissection extension into the abdominal aorta is acceptable.

This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) Model 9600TFX and associated delivery systems for the aortic valve in valve procedure. Participants in this study will have the investigational (experimental) Edwards SAPIEN 3 transcatheter aortic heart valve (study device) to replace the failing bioprosthetic aortic valve access through the heart through a small incision is in the chest. The study device and its delivery system are investigational, which means they are not approved for commercial use by the U.S. Food and Drug Administration (FDA) for the valve in bioprosthetic valve procedure. The previous generation of SAPIEN valves, SAPIEN XT, was approved for commercial use by the FDA for a failed surgical bioprosthetic aortic valve in October 2015. The study device is a bioprosthetic heart valve made out of man-made materials and animal tissue. It is an artificial device made to replace the diseased aortic heart valve. Each valve consists of a stent (mesh tube made of metal) to hold the study device in its intended position and valve leaflets (made of biological material derived from cows) to direct the flow of blood in the heart. Study participation will last approximately 10 years. Participants will be asked to come to clinic for study visits at 30 days, 6 months, and 12 months after the study procedure and then annually until 10 years after the procedure. We expect up to 19 people will be enrolled at Northwestern. The study expects to enroll up to 125 people internationally.
*Main Inclusion Criteria*
Failing surgical or transcatheter bioprosthetic valve in the aortic position demonstrating ≥ moderate stenosis and/or ≥ moderate insufficiency.

*Main Exclusion Criteria*
Surgical or transcatheter valve in the mitral position (mitral rings are not an exclusion).
Severe regurgitation (>3+) or stenosis of any other valve.
Failing valve is unstable, rocking, or not structurally intact.

This study is recruiting people who have Type 2 diabetes mellitus (T2DM) or prediabetes and heart failure (Inability of the heart to pump blood with normal efficiency). The purpose of the study is to find out if a drug called dapagliflozin would be effective in improving the blood tests and symptoms related to heart failure while also treating type 2 diabetes or potentially preventing type 2 diabetes if you have pre-diabetes. To do this, dapagliflozin will be compared with placebo. The placebo will look like dapagliflozin but is inactive.

Under normal circumstances, the sodium-glucose transporters in the kidney prevent glucose in the blood stream from leaving the body through urine. Dapagliflozin inhibits the sodium-glucose transporters and lowers blood glucose by allowing glucose removal through the urine. Dapagliflozin may also mildly decrease body weight and lower blood pressure in certain patients. Dapagliflozin is approved by the United States Food and Drug Administration (FDA) for the treatment of type 2 diabetes. Dapagliflozin is not specifically approved for the treatment of type 2 diabetes in people with heart failure and therefore its use in this study is investigational.

The main reason for the study is to determine whether aortic valve replacement with the Edwards SAPIEN 3 THV (the “Study Device”) is helpful for patients who have severe, calcific, aortic stenosis (a narrowing of the aortic heart valve, where calcium has attached to the valve surface, resulting in obstructed blood flow) and do not have symptoms. The Study Device is a bioprosthetic heart valve. It is an artificial device made to replace your diseased aortic heart valve. Each valve consists of a stent (mesh tube made of metal) to hold the valve in position and valve leaflets (made of biological material derived from cows) to direct the flow of blood in your heart. The Study Device and its delivery system are not approved for commercial use by the U.S. Food and Drug Administration (FDA) in patients that do not have symptoms of aortic stenosis. To date, more than 12,000 patients have been enrolled in clinical studies with an Edwards THV. The SAPIEN 3 THV that is being investigated for this study has been implanted in over 3,000 patients with symptoms of severe aortic stenosis and has been approved by FDA for those patients. Participation in the study will vary, depending upon the treatment group you are assigned. If you are in the TAVR group, your participation will be for 5 years. If you are in the Clinical Surveillance group, your participation could range from 5 to 10 years. If you are in the registry group, your participation will be for 5 years. We expect up to 166 people will participate in the main study and up to up to 150 in the registry here at Northwestern. A total of 1109 patients will participate in the main study and up to 1000 patients will participate in the registry internationally.
Inclusion Criteria:
Severe aortic stenosis
Patient is asymptomatic
The study patient has been informed of the nature of the study, agrees to its provisions and has provided written informed consent as approved by the institutional review board of the respective clinical site.

Exclusion Criteria:
Patient is symptomatic.
Ilio-femoral vessel characteristics that would preclude safe placement of the introducer sheath.
Evidence of an acute myocardial infarction ≤ 1 month (30 days) before randomization.
Aortic valve is a unicuspid, bicuspid, or is non-calcified.
Severe aortic regurgitation (>3+).
Severe mitral regurgitation (>3+) or ≥ moderate mitral stenosis.

This study is recruiting patients who have a condition called “nonvalvular atrial fibrillation.” Normally, electrical signals from the upper chambers of the heart (atria) travel to the lower chambers of the heart (ventricles) and cause them to beat in a regular way. During atrial fibrillation, the electrical signals in your heart are not normal and cause the upper chambers of the heart to beat too fast and irregularly. This irregular beating of the heart leads to a slowing of the blood flow in the upper chambers of the heart. In the left upper chamber, there is a small pouch called the left atrial appendage (LAA). Slowing of blood, especially in the LAA, may cause blood clots to form. Blood clots can move from the LAA and travel to the brain, causing a stroke or transient ischemic attack (TIA), also called a mini-stroke. These blood clots can also travel to other parts of the body and block blood vessels. The purpose of the AMPLATZER Amulet Left Atrial Appendage (LAA) Occluder Trial is to find out if the investigational (not yet approved by the FDA for use in the US) Amulet device is safe and effective when compared to an FDA-approved device called the WATCHMAN LAA closure device. We expect up to 25 people here will be in this research study out of 1700 people in the entire study internationally. Participants will be involved in this research study for up to 5 years. After the procedure, participants will be asked to come to clinic for 5 in-person study visits, and will be contacted via telephone by the study team 5 times.

The research project is testing a new treatment for mitral regurgitation. The new treatment is a mitral valve replacement with a new investigational device called the Twelve Transcatheter Mitral Valve Replacement (TVMR) System. This research study is an early feasibility study, which is done to study a device that has not been used in many people. Mitral valve regurgitation (MR) occurs when the two leaflets of the mitral valve do not close correctly and blood leaks backward with each heartbeat. If left untreated, there is a risk that the heart may begin to fail and patients may have symptoms such as shortness of breath or tiredness. One treatment for MR is open-heart surgery to replace a leaky mitral valve with an artificial heart valve. A standard valve implant, however, is sewn directly into the heart during surgery in which the chest is fully open and requires heart-lung bypass support and the heart is temporarily stopped to sew in the valve. The TMVR device is intended to be placed through a less invasive procedure, without sewing, and without requiring heart-lung bypass support and stopping the heart.

The purpose of this study is to evaluate the safety and effectiveness of an investigational device for heart failure symptoms. Investigational means it has not been approved by the USA Food and Drug Administration (FDA).The device is called the IASD System II, which is an “inter-atrial shunt”. The device is permanently implanted into the heart. It is designed to reduce the pressure in a part of the heart called the left atrium. This is done by creating a small opening between the left atrium and the right atrium of your heart. If it lowers the pressure in your heart at rest or during activity, it may lessen some of the symptoms you have. You have a 50% chance of receiving the device and a 50% chance of being in the control group for 2 years and then you may have the option of receiving the device This study is an FDA approved clinical trial for this device. The FDA will review the safety results and the treatment effect found in this study. If the FDA accepts the research results the FDA can approve the device for sale in the USA. In April 2016, the Study Device received CE Marking, which is an approval that allows it to be sold in the European Union. If you agree to participate in this study, we expect that you will be involved for about five (5) years. Being in this study requires regular doctor visits. There are visits for testing before the procedure. After the procedure, there are visits at 1 month, 3 months, 6 months and 12 months, and then yearly visits until 5 years after the procedure. The study is over when all the subjects have had their last doctor visit. We expect up to 12 people here will be in this research study out of 700 people in the entire study internationally

An Abdominal Aortic Aneurysm (AAA) is a balloon-like expansion of the aorta, the large artery that transports blood from the heart to the rest of the body, in the abdominal area just below the kidneys. As part of routine monitoring care for patients diagnosed with AAA, at least semi-annual evaluations are performed using imaging methods such as a computed tomography (CT) scan. Magnetic Resonance Imaging (MRI) is another method of creating pictures of the same vessels seen on a CT scan. MRI is a method for producing extremely detailed pictures of blood vessels without the need for x-rays. Radio waves, along with the magnetic field of a large magnet within the MRI machine, are used to make the pictures. MR images are used to detect and aid in the diagnosis of heart disorders and blood vessel diseases. For the purpose of this research, along with the routine CT scan, an additional scan called a ECG-gated MRI exam will be performed. This MRI exam does not involve any contrast, a dye used to make tissues, abnormalities or diseases processes more visible. This one-time MRI exam will be performed prior to anticipated elective AAA repair or during the course of periodic surveillance for AAA. This research study plans to enroll approximately 200 study participants at approximately 3 sites, including approximately 100 people at Northwestern.
Participants may be eligible for this study if they have been diagnosed with an AAA and either have been recommended to undergo elective AAA repair or are currently under periodic surveillance for AAA.

The purpose of this study is to collect information over time regarding the safety and effectiveness of the Arctic Front Advance™ Cardiac CryoAblation Catheter and the Freezor MAX® Cardiac CryoAblation Catheter for the treatment of persistent AF. This study is required by the FDA in the United States to expand the use of the Arctic Front Advance Cardiac CryoAblation Catheter and the Freezor MAX Cardiac CryoAblation Catheter to a new population. Catheter ablation is a minimally invasive procedure that may lessen the number of episodes or treat your atrial fibrillation. The doctor threads a flexible thin tube (catheter) through the blood vessels to the heart to terminate (ablate) abnormal electrical pathways in the heart tissue. In this study, this will be done using the Arctic Front Advance Cardiac CryoAblation Catheter and the Freezor MAX Cardiac Cryoablation Catheter. The Arctic Front Advance Cardiac CryoAblation Catheter mentioned above is approved by the US Food and Drug Administration (FDA) for use in patients who have recurrent symptomatic drug refractory paroxysmal AF. The Freezor MAX Cardiac CryoAblation Catheter is approved by the FDA for use with the Arctic Front Advance Cardiac CryoAblation Catheter in patients who have paroxysmal AF. For this study, these catheters will be used in patients who have recurrent symptomatic drug refractory persistent AF, and therefore will be considered investigational. We expect up to 20 people at Northwestern University will be in this research study out of about 225 people in the entire study worldwide. We expect that participation will last about 12 months.

The purpose of this research study is to find out if PerClot is safe and effective as a part of surgery to stop bleeding. PerClot is a device in granule form made from the starch of a potato. The starch has been engineered in a way that the powder absorbs water and helps to form a clot. This kind of device (topical hemostat) is intended for use in surgical procedures as an adjunctive hemostatic device when control of capillary, venular, and arteriolar bleeding by pressure, ligature, or other conventional procedures is ineffective or impractical. PerClot is left in your body after surgery. In animal studies, it has been found that PerClot is absorbed by the body in a few days after surgery. This has not been demonstrated in humans and can vary depending on the amount of device applied. This can also depend where it is applied. This research study will collect follow-up data after PerClot is used. PerClot is an investigational device in the United States. This means it has not been approved by the Food and Drug Administration (FDA). PerClot has been an approved medical device in Europe since 2008. This research study plans to enroll approximately 324 study participants at approximately 25 U.S. sites, including approximately 10 people from this institution. We expect that participants will be in this research study for approximately 6 weeks; however, if you currently have, or are diagnosed with cancer during the study, you will be contacted by the study coordinator on the telephone at 24 months after your surgery to ask questions about your general health. Research Trial Contact Information: For more information, participants and clinicians may contact the research team at (312) 926-4000 or heartresearch@northwestern.edu.

Annular ReduCtion for Transcatheter Treatment of Insufficient Mitral ValvE (ACTIVE): A prospective, multicenter, randomized, controlled pivotal trial to assess transcatheter mitral valve repair with Edwards Cardioband System and guideline directed medical therapy (GDMT) compared to GDMT alone in patients with functional mitral regurgitation (FMR) and heart failure.
This study is enrolling patients with moderate-to-severe or severe functional mitral regurgitation (FMR). FMR occurs when the two leaflets of the mitral valve do not close properly, causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward. This can lead to shortness of breath and make the heart weaker because it cannot pump enough blood for the body’s needs. The purpose of this study is to evaluate a new device to treat patients who might benefit from repair of their mitral heart valve due to functional mitral regurgitation. The device is called the Edwards Cardioband System (“Edwards Cardioband System”). The device is investigational, which means it is not yet approved by the U.S. FDA for sale in the United States. This device is placed without the need for an open-heart procedure and without the need for a heart and lung machine. Instead, the device is delivered using a less invasive approach where the Cardioband System is inserted through a vein in the groin and threaded to the heart using a delivery catheter (small plastic tube). For this study patients will be “randomized” or assigned by chance to one of two study groups: Device group or the Control group. Patients will be randomized 2:1, which means each patient has a 2 to 1 chance of being assigned to the Device group (twice as likely to be in the Device group as the Control group). Subjects assigned to the Control Group may be eligible to receive the Study Device after their 1 year study visit. Participation in this study will last for approximately 5 years. Both Device and Control Group participants will be asked to return for visits at 1 month, 6 months, and 1, 2, 3, 4 and 5 years. This study is being conducted in up to fifty (50) hospitals in the United States, Canada, and/or Europe and plans to enroll up to 525 participants, including approximately 10 people from this institution
Inclusion: 1. Functional MR (≥ 3+ by echo); 2. Patient hospitalized due to heart failure during 12 months prior to enrollment OR BNP >400 pg/ml or NT‐BNP>1500 pg/ml; 3. LVEF > 20% and LVEDD ≤ 70mm 4. NYHA Class II‐IVa heart failure symptoms despite medical therapy Exclusion: 1. Degenerative MR including mixed degenerative/functional MR; 2. Severe mitral annular calcification; 3.

The purpose of this study is to find out whether a drug called “macitentan” works and is safe in patients with Heart Failure with Preserved Ejection Fraction and Pulmonary Vascular Disease. There are several drugs available to manage heart failure symptoms, but to date, no treatments have been approved specifically for left heart failure with preserved ejection fraction and pulmonary vascular disease. Macitentan may reduce unwanted effects of a chemical substance in the body called endothelin, which has been detected in increased amounts in patients with heart failure. Endothelin causes blood vessels to narrow and results in overgrowth of the muscle in the walls of the lung blood vessels and also of the heart. By blocking the action of endothelin, macitentan lowers the blood pressure in the pulmonary arteries, may slow down overgrowth of the heart muscle and may therefore improve your condition. Macitentan has been tested and approved in the U.S. for other diseases, but is considered experimental for the use in this study. We expect participants will be in this research study for 70 weeks, and will need to come to clinic for study visits 13 times. We expect up to 5 people here will be in this research study out of 300 people in the entire study internationally.
*Inclusion Criteria*:
Signs or symptoms of Heart Failure (HF) requiring treatment with at least one oral diuretic (any type) . Left ventricular ejection fraction (LVEF) ≥ 40% . Structural heart disease consistent with heart failure with preserved ejection fraction (HFpEF).
HF hospitalization within 12 months prior to Screening and/or cardiac catheterization performed within 6 months prior to Screening showing PAWP or LVEDP > 15 mmHg. Elevated NT-proBNP.
Pulmonary vascular disease or right ventricular dysfunction

Exclusion Criteria:
Any prior measurement of LVEF < 40%.
Cardiovascular co-morbidities (e.g., significant unrepaired structural valvular heart disease; acute coronary syndrome, coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) within 3 months of Screening; uncontrolled heart rate from atrial fibrillation or atrial flutter, history of serious life-threatening or hemodynamically significant arrhythmia) Hemoglobin < 100g/L (< 10 g/dl) Significant lung disease (e.g., severe COPD, moderate or severe restrictive lung disease, diffuse interstitial fibrosis or alveolitis, pulmonary thromboembolism)
Severe renal dysfunction with an estimated Glomerular Filtration Rate (eGFR) < 30 mL/min per 1.73 m2
Severe hepatic impairment, e.g., Child Pugh Class C.

REVAMP: The purpose of this study is to see if pacing the right atrium of the heart at a higher rate for periods of time can help the left ventricle (LV) pump blood better, and if it improves exercise capacity and quality of life for patients who have HFpEF, normal to small LV chambers, and evidence of thickened walls. This study will be conducted with patients who have a market-released Medtronic dual chamber pacemaker with a Sleep Function, and have had this pacemaker for at least 6 months. Any Medtronic dual chamber pacemaker with the Sleep Function will qualify. In patients with HFpEF, the chamber of the heart that pumps blood out to the body tends to be stiff with thickened walls, reducing the amount of blood that can be pumped with each heartbeat. Previous research suggests that raising the heart rate may reduce the thickness of the heart chamber walls and increase the amount of blood pumped with each heartbeat. This research study plans to enroll approximately 40 study participants at approximately 5 sites, including approximately 15 people from this institution. Research Trial Contact Information: For more information, participants and clinicians may contact the research team at (312) 926-4000 or heartresearch@northwestern.edu.
Inclusion criteria:
• Subject has had a market released dual chamber Medtronic Pacemaker with a Sleep function for at least 6 months

This study is enrolling subjects with severe symptomatic mitral regurgitation to test a new investigational device for mitral regurgitation. The new investigational device is a mitral valve replacement called the IntrepidTM Transcatheter Mitral Valve Replacement (TMVR) System. The purpose of the TMVR device is to function similarly to a standard bioprosthetic (man-made) valve implant in that it allows blood to flow only in the forward direction, relieving mitral regurgitation. A standard valve implant, however, is sewn directly into the heart during surgery in which the chest is fully open, the patient is put on heart-lung bypass support and the heart is temporarily stopped to sew in the valve. The TMVR device is intended to be placed through a less invasive procedure, without sewing, and without requiring heart-lung bypass support or stopping the heart.
INCLUSION: 1) Subject has severe symptomatic mitral regurgitation as defined by the ASE. 2) Patient is a candidate for bioprosthetic mitral valve replacement EXCLUSION: 1) Prior mitral valve surgery including previously implanted mitral valve, ring, or band. 2) Heart Team agrees predicted risk of operative mortality is <3% at 30 days or has ≥35% risk of mortality or irreversible major morbidity at 30 days. 3) mitral anatomy that would preclude management of the sub-valvular apparatus and/or full chordal sparing

Dilated cardiomyopathy (DCM) is a condition in which the heart becomes enlarged and the heart muscle weakened, causing the heart to pump blood less efficiently. DCM is commonly caused by heart muscle damage (“a heart attack”) from coronary artery disease. Other causes include exposure to some drugs, such as cancer chemotherapy. When the cause is unknown, it is called idiopathic DCM. Among individuals with idiopathic DCM, having relatives undergo a cardiac check-up (echocardiogram, ECG) will reveal familial DCM in up to one-third of cases. A high level of suspicion of familial DCM is also raised when family members have had heart failure, a heart transplant, sudden death (without a history of coronary artery disease), or arrhythmias, which sometimes require a pacemaker or defibrillator. WHAT DOES THIS STUDY INVOLVE? IF YOU HAVE IDIOPATHIC DCM: Participation involves inviting all your first-degree relatives (children, parents, siblings) with or without heart disease. If you have other more distant relatives with DCM, they are also welcome to participate. To help with this process, we provide a letter that you can share with your relatives, and a family history questionnaire for you to complete. You may also receive a communication tool to help you invite your family members to the study. Your participation also involves providing cardiovascular information and medical records, completing annual surveys, and a blood draw. FOR FAMILY MEMBERS: Participation of family members involves collecting cardiac information and a blood draw. To better understand the genetic cause of DCM, it is helpful to compare results from family members with and without the condition. Because DCM can be present but silent for years, it is difficult to know with certainty if a family member does or does not have DCM unless a cardiac check-up is performed. Medical guidelines recommend this for 1st degree family members of individuals with DCM. Therefore, we also ask family members who enroll to obtain cardiac screening with both an echocardiogram and an electrocardiogram (ECG) if they have not done so recently.
Inclusion Criteria:

Meeting criteria for dilated cardiomyopathy (DCM) :
Left ventricular ejection fraction <50%
Left ventricular enlargement (A left ventricular end-diastolic dimension > 95%tile population standard based on gender and height).
Detectable causes of cardiomyopathy, except genetic, excluded beyond a reasonable doubt at the time of DCM diagnosis (that is, meeting clinical criteria for idiopathic DCM)
Any age (including children)
Non-Hispanic and Hispanic ethnicity
All races (PI pre-approval required for recruitment beyond pre-specified recruitment targets).
Ability to give informed consent
Ability to communicate in English (except Spanish language at sites approved to recruit individuals of Hispanic ethnicity)
Willingness to participate in a family-based study (patient willing to work with a clinical site and/or OSU to facilitate the recruitment and enrollment of family members to the study).

Exclusion Criteria:

Coronary artery disease (CAD) causing ischemic cardiomyopathy (> 50% narrowing, any major epicardial coronary artery)
Primary valvular disease
Adriamycin or other cardiotoxic drug exposure
Other forms of cardiomyopathy: Hypertrophic, Restrictive, or Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy
Congenital heart disease
Other detectable causes of dilated cardiomyopathy, including sarcoid and hemochromatosis.
Other active multi-system disease that may cause DCM (e.g., active connective tissue disease).
Severe and untreated or untreatable hypertension (systolic blood pressures routinely greater than 180 mm Hg and/or diastolic blood pressures greater than 120 mm Hg, and if resistant to multidrug treatment).
However, conventional risk factors for DCM, including obesity, routinely treated hypertension, alcohol use, pregnancy or the peri-partum period, or left ventricular noncompaction, will NOT be considered exclusion criteria.

This study is recruiting patients with tricuspid regurgitation (a condition in which blood flow through the tricuspid valve of the heart flows in the wrong direction) that may benefit from a new tricuspid valve reconstruction system. This is an early feasibility clinical research study that will evaluate the safety and performance of the Edwards Cardioband Tricuspid Valve Reconstruction System, (the “Study Device” ). The Study Device includes an adjustable implant that is delivered and anchored to the tricuspid valve by a transfemoral delivery system, meaning it is inserted in a minimally invasive procedure through a puncture into a vein in the leg. The Cardioband Implant will be positioned around the tricuspid valve and will be adjusted to reduce the size of the valve, thus improving the tricuspid regurgitation. Up to 15 patients will be enrolled in this study at up to 15 sites. All enrolled study patients will be assessed at the following intervals: screening/baseline, procedure, discharge, 1 month, 6 months, 1 year and annually for 5 years post implant procedure.
