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.

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.

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.

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 research study plans to enroll up to 435 study participants at approximately 40 sites across the country, including up to 5 people from this institution.
Primary Inclusion Criteria:

  • Presence of thoracic aortic pathology deemed to warrant surgical repair which requires proximal graft placement in Zone 0-2.

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
  • Proximal and distal aortic neck with diameter between 19 mm and 42 mm.
Exclusion Criteria:

  • 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.

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 enrolling patient who have heart failure (inability of the heart to pump blood with normal efficiency).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 your heart failure. To do this, dapagliflozin will be compared with placebo. The placebo is a pill that will look like dapagliflozin but will not have active ingredients. Dapagliflozin lowers glucose (sugar) levels in the blood by blocking the effect of specific molecules (small particles) in the body called sodium-glucose transporters. Under normal circumstances, the sodium-glucose transporters in the kidney prevent glucose in your blood stream from leaving the body through urine. Dapagliflozin inhibits the sodium-glucose transporters and lowers the blood glucose by allowing glucose removal through the urine. Dapagliflozin may also mildly decrease body weight and lower blood pressure in certain patients. Decreasing body weight and lowering blood pressure may improve the blood tests and symptoms related to heart failure.

  • Age > 18 and < 120 at the screening visit
  • Symptoms of dyspnea (NYHA class II-IV) without evidence of a non-cardiac or ischemic explanation for dyspnea
  • Ejection fraction (EF) ≥ 45% as determined on imaging study within 24 months of enrolment with no change in clinical status suggesting potential for deterioration in systolic function
  • Elevated NT-proBNP (≥ 225 pg/ml) or BNP (≥ 75 pg/ml)
  • Stable medical therapy for heart failure for 15 days as defined by: i. No addition or removal of ACE, angiotensin receptor blockers (ARBs), valsartan/sacubitril, beta-blockers, calcium channel blockers (CCBs) or aldosterone antagonists ii. No substantial change in dosage (100% or greater increase or decrease from baseline dose) of ACE, ARBs, beta-blockers, CCBs or aldosterone antagonists
  • On a diuretic ≥15 days prior to screening visit and a stable diuretic therapy for 7 days

This trial is enrolling patients who have aortic stenosis and are undergoing a transcatheter aortic valve replacement or a surgical aortic valve replacement. This research is being performed to evaluate wearable activity monitors (specifically, FitBits will be used) in patients with aortic stenosis undergoing a procedure to fix their aortic stenosis. Many patients with aortic stenosis have low activity levels which improve after undergoing a procedure to fix their aortic stenosis, but the current methods used to assess activity levels are limited. This study will use a unique method (wearable activity monitors) to continuously track activity, both before and after the procedure. We are interested in comparing this method to the traditional methods used, which includes a 6 minute walk test and an assessment of the ability to engage in physical activity as determined by study coordinators and/or the physician through a conversation with patients. We are also

interested in assessing quality of life through surveys to determine how that relates to activity data.

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.

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 Abdominal Aortic Aneurysm and either have been recommended to undergo elective repair or are currently under periodic surveillance for AAA.

This study is enrolling subjects with moderate-to-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.
Enrolling participants with mitral valve regurgitation that are at high risk of experiencing major complications while undergoing open-heart surgery due to their current medical conditions or anatomical reasons (relating to how and where the heart, mitral valve, and blood vessels are placed within the body). Additionally, physicians determined condition may not be optimally treated with currently approved transcatheter repair therapies.

This study is enrolling patients whose existing bioprosthetic mitral valve is failing and needs to be replaced and who are considered at intermediate risk for open heart surgery. This research study will evaluate the safety and effectiveness of the SAPIEN 3 Transcatheter Heart Valve (THV) in patients with a failing mitral bioprosthetic valve. Transcatheter valve replacement is a catheter-based technique for replacing the failing valve, which is less invasive than open-heart surgery.
This study will enroll patients with symptomatic heart disease due to a failing bioprosthetic mitral valve (stenosed, insufficient, or combined)

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 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.

    The purpose of this study is to evaluate the use of a device to treat patients with Heart Failure (HF - inability of the heart to pump enough blood to meet the body's needs) who have moderate aortic stenosis (AS - narrowing of the aortic valve resulting in obstructed blood flow). This clinical trial is comparing the safety and effectiveness of TAVR (Transcatheter Aortic Valve Replacement) with the Edwards SAPIEN 3 Transcatheter Heart Valve (the Study Valve) and OHFT (optimal heart failure therapy) versus OHFT alone in HF patients with moderate AS. The study valve has not been approved by the U.S. Food and Drug Administration (FDA) for use in this patient population, and therefore it's use in this study is considered investigational.
    This study is looking for patients with Heart Failure and moderate Aortic Stenosis. Aortic Stenosis is a narrowing of the aortic valve opening,which blocks blood flow from the heart and causes symptoms such as chest pain,fainting and shortness of breath.

    This study is enrolling patients who have been diagnosed with a non-paroxysmal form of atrial fibrillation (persistent or longstanding persistent) and whose doctor determined that they need surgery to correct their AF, along with another heart problem (i.e., heart valve or blocked artery). Atrial fibrillation (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. People may participate in this clinical research trial if their study doctor has determined that they have a certain type of AF and require surgery to correct another heart problem other than AF. The purpose of this study is to evaluate safety and effectiveness of the cryoICE Cryoablation System, in conjunction with LAA exclusion using the AtriClip device, in patients with persistent or longstanding persistent atrial fibrillation who are having heart surgery for another reason. AtriCure’s cryoICE Cryoablation System has been cleared by the FDA to ablate cardiac tissue for the treatment of non-specific cardiac arrhythmias in patients who are undergoing open heart surgery. However, the cryoICE Cryoablation System is not approved by the FDA specifically for the treatment of atrial fibrillation and therefore its use is considered investigational in this study.

    This study is enrolling patients who have Acute Decompensated Heart Failure (ADHF) and are having or recently had a cardiac catheterization procedure as part of their clinical care (not part of the research).The reason we are doing this research study is to look at the preCARDIA device (the “study device”) to see if it can help treat Advanced Heart Failure. This type of research study is called an “early feasibility study”. Early feasibility studies typically evaluate innovative devices or innovative uses of approved devices. These studies enroll a small number of participants and provide initial information on the basic safety and performance of the study device when used to treat a specific patient type. The study device is investigational and not approved by the US Food and Drug Administration (FDA) for your medical condition. In patients with advanced heart failure, specifically severely congested patients with Acute Decompensated Heart Failure (ADHF), poor heart function leads to an excess of fluid in the right side of the heart (“fluid overload”) and symptoms such as shortness of breath. Drugs such as diuretics are designed to improve these symptoms and heart function by reducing fluid overload. However, diuretics take time to work and may be ineffective in patients with advanced heart failure, a phenomenon known as diuretic resistance. For this reason, a device-based approach designed to limit fluid overload is being studied to see if it could possibly improve symptoms and heart function in congested patients with advanced heart failure. The study device will temporarily block (“occlude”) one of the veins that return blood to the heart in order to potentially reduce fluid buildup and potentially improve the heart’s pumping function temporarily.

    This study is enrolling patient who have an irregular heart rhythm called atrial fibrillation (AF) and are scheduled for a first-time AF ablation procedure to treat their AF. Current techniques used during AF ablation procedures to try and reduce potential damage to the esophagus during ablation are limited. The purpose of this study is to determine if esophageal warming using the Attune Medical Esophageal Heat Transfer Device (ensoETM) limits the injury to the esophagus during atrial fibrillation ablation procedures. The ensoETM is an FDA approved device used for temperature management, but is not routinely used during atrial fibrillation ablation procedures.

    This study is enrolling patients who have a patent foramen ovale (PFO), have had a stroke of unknown origin (cryptogenic stroke), and whose doctor has decided they are a candidate for a transcatheter procedure (a procedure performed through a flexible tube inserted through a narrow opening into a small incision in the skin) to close their PFO. A PFO is a common opening in the wall (septum) between the two upper chambers (the right and left atria) of your heart. In most cases, this opening closes around the time of birth. If the opening remains after birth, it can allow the blood to mix in the two upper chambers of the heart. This post-market study will look at closing the PFO to reduce the risk for another stroke using a market-approved medical device called a septal occluder. This device is called the ‘GSO device’ in this description. The GSO device is a minimally invasive device intended for the closure of a PFO using cardiac catheterization. It is a permanent implant consisting of a near circular wire frame covered with thin material. The soft, conformable material, invented and manufactured by Gore, has been used in open-heart surgery for more than 40 years and has been shown to be safe in implanted medical devices. The wire frame is made of a nickel-titanium metal alloy called nitinol with a platinum core (so that it may be seen on X-ray images).

    This study is enrolling patients who have high blood pressure ("hypertension") and are taking two medications or fewer for it. It is believed that in some patients with high blood pressure, the nerves surrounding the blood vessels leading to the kidneys (renal arteries) are too active and that this may be causing high blood pressure. Renal denervation is a procedure where a catheter is placed inside these blood vessels and creates heat to disable the nerves and potentially lower blood pressure. The purpose of this clinical study is to see whether a medical device called the Paradise Renal Denervation System (also called The Paradise System) can lower high blood pressure in patients who are known to have hypertension.

    This study is enrolling patients with severe Tricuspid Regurgitation (TR), a condition in the heart’s tricuspid valve does not close tightly which causes the blood to flow in the wrong direction. The standard medical treatments generally available to patients with tricuspid regurgitation who do not undergo surgery, may temporarily alleviate some symptoms, but will not permanently alleviate or cure tricuspid regurgitation.  The goal of this trial is to evaluate the safety and effectiveness of the Edwards PASCAL Transcatheter Valve Repair System (hereinafter referred to as the PASCAL System) with optimal medical therapy (OMT) compared to OMT alone in the treatment of participants with symptomatic severe tricuspid regurgitation who may not be ideal candidates for tricuspid valve surgery (performed via open-heart surgery) and may be eligible for transcatheter tricuspid valve repair (minimally invasive procedure that repairs the valve). Optimal Medical Therapy (OMT) refers to standard of care treatment using recommended medications

    RV Ischemia & Fibrosis in CTEPH

    This study is enrolling patients who have been diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH) and who are scheduled for a pulmonary endareterectomy (PEA) or balloon pulmonary angioplasty (BPA) procedure for treatment. CTEPH is high blood pressure in the arteries in the pulmonary system (lungs) caused by clots. Over time the clots typically leave scar tissue (fibrosis) in the arteries and lead to poor blood supply to the heart. In patients with CTEPH symptoms of heart failure commonly result from dysfunction (not working correctly) in the right ventricle (RV), or the chamber of the heart that pumps blood to the lungs. However, little is currently known about why or how that chamber of the heart becomes dysfunctional in patients with this condition. In another chamber of the heart, the left ventricle, it is known that elevated blood pressure in that chamber causes the development of diffuse fibrosis, or scarring between the muscle fibers, and a similar process may take place in the right ventricle of patients with CTEPH.

    For this study a cardiac magnetic resonance imaging (MRI) stress test (also known as stress CMR) will be done to look at the RV in patients with CTEPH before and 6 months after treatment. A stress CMR is a specialized scan of the heart that examines fibrosis (scarring) and blood flow (perfusion) both at rest and under stress. A gadolinium contrast agent (MRI dye) is given to highlight the heart muscle in areas receiving a good blood supply. Areas receiving less blood do not highlight as well as the good areas, which can be an indicator of ischemic heart disease (undersupply of blood and oxygen to the heart).

    This study is enrolling patients to use a wearable insertable cardiac monitor to better understand the various sounds that the heart makes during cardiac tests. You are being asked to participate in this study because Boston Scientific Corporation (BSC) is making a device called the insertable cardiac monitor (ICM) that measures certain heart functions. The device also works when it is placed on top of the chest. BSC made a more comfortable, wearable version of the device to use in this study. The wearable device is called the wearable cardiac monitor (WCM). As part of the study, the WCM will collect data during tests while taped to the skin. The tests include leg raise exercises, lying down, sitting and/or standing, and an optional submaximal exercise test for participants the study doctor determines appropriate. There may also be an echocardiogram during these tests. An echocardiogram takes pictures of the heart using sounds waves created by the heart. The purpose of this study is to collect data during a series of tests to see if the WCM can detect signals related to heart failure. This data will be compared to the data obtained by the echocardiogram.

    This study is enrolling patients who have an aortic aneurysm involving the visceral branch blood vessels (vessels that provide blood to the kidneys) that requires treatment. The aorta is a large blood vessel that carries blood away from the heart to organs in the rest of the body. This research study will look at treating thoracoabdominal or pararenal aneurysm disease with a new device design known as the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (the ‘Study Device’).The Study Device that will be used to treat the aneurysm is called a “stent-graft”. The Study Device combines a surgical graft material with an outer metal mesh-like form (stent). The nonmetal graft component of the Study Device is made of a soft, polymer material (ePTFE). This material is routinely and safely used for surgical procedures throughout the world today. The graft is surrounded on the outside with a metal frame made from an elastic metal (nitinol wire or stainless steel) bent into a wave pattern and shaped to fit the graft. The materials used in the Study Device are not investigational and have a long, safe history of performance in similar applications.

    The purpose of this research study is to compare health outcomes of patients diagnosed with Primary MR who have their MV repaired with open heart surgery, which is the current standard treatment, to patients who have their Mitral Valve repaired with the MitraClip System. The MitraClip System uses a less invasive procedure to repair the mitral valve.

    Subjects are asked to participate in this Study because they have moderate-to-severe or severe MR and it has been determined to have symptoms due to heart failure despite being treated with currently available therapies. MR occurs when the 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 needs to pump more blood with each beat to push the same amount of blood forward.

    The Study will enroll approximately 500 subjects at up to 60 sites in Europe, United States, and Canada. The Study consists of two arms: Device Arm and Control Arm.

    • Subject has severe (Grade III or greater per the ASE criteria, which includes severitygrades of 3+ and 4+) primary MR (mixed etiology is acceptable provided theprincipal mechanism of action is a degenerative mitral valve) as assessed bythe ECL.
    • Subject is at least 75 years of age

    This study is enrolling patients who have severe Tricuspid Regurgitation (TR), a condition in which the heart’s tricuspid valve does not close tightly which causes the blood to flow in the wrong direction. This condition increases the workload on the heart and if left untreated, it can increase the risk of failure. The standard medical treatments generally available to patients with tricuspid regurgitation who do not undergo surgery may temporarily alleviate some of their symptoms but will not permanently alleviate their condition or cure their tricuspid regurgitation. This research project is testing a new investigational device, the Edwards EVOQUE Replacement System (called the EVOQUE System) for treatment of TR. The goal of this study is to evaluate the safety and performance of the EVOQUE System in subjects with at least moderate TR and signs of TR, symptoms from TR or prior heart failure hospitalizations from TR.

    This study is enrolling patients who have obstructive hypertrophic cardiomyopathy (oHCM). Obstructive HCM is a condition in which the heart muscle in the left ventricle (LV) becomes abnormally thickened, which can block blood flow out of the heart to the body. This obstruction causes the LV heart muscle to work harder to pump blood to the body and can cause symptoms of chest pain, dizziness, shortness of breath and fainting. This is the first time the investigational drug called CK-3773274 is being studied in participants who have oHCM, but it has already been studied in healthy volunteers. The purpose of this study is to learn how well CK-3773274 is tolerated at different, increasing dose levels in patients with oHCM and if it causes any side effects. The study will also measure the amount of CK-3773274 in your blood at various times, and the effect the study drug may have on your oHCM. CK-3773274 is an investigational (experimental) study drug. This means that CK-3773274 has not been approved by the U.S. Food and Drug Administration (FDA) for use outside of a research study.

    This study is enrolling patients who have transthyretin-mediated amyloid cardiomyopathy (ATTR-CM) which is a disease caused by change in a protein called transthyretin (TTR). This change can either be sporadic which is known as wild-type (wtATTR-CM) or due to a mutation of the TTR gene which is hereditary (hATTR-CM). In both cases, these changes can cause the TTR to clump and build up in certain parts of the body such as the nervous system, stomach, intestines, and heart. This build up is called an amyloid deposit. Amyloid deposits can sometimes cause heart disease or neuropathy (nerve damage). When amyloid is deposited into the heart, it can result in a condition referred to as cardiomyopathy. ION-682884 is an investigational drug. “Investigational” means that ION-682884 is not yet approved for use in any settings outside of clinical research studies like this one and is considered experimental. ION-682884 reduces the level of TTR in the blood of animals and healthy volunteers tested to date. Reducing the amount of TTR in the blood may reduce the amount of amyloid deposits in the body and may keep cardiomyopathy from getting worse over time. However, it is not known if ION-682884 will help cardiomyopathy. The purpose of this study is to evaluate the safety of ION-682884 and determine if it can help people with this type of cardiomyopathy.

    This study is enrolling patients who had an On-X mechanical valve implanted in the aortic position at least 3 months (90 days) ago, are currently receiving warfarin anticoagulation, and are able to receive warfarin with a target INR (measurement of how long it takes for blood to form a clot) of 2.0 to 3.0.  Studies have shown that patients who get tissue valves instead of mechanical valves (On-X Prosthetic Heart Valve / On-X valve) usually have to be operated on again. However, patients who get mechanical valves need to take warfarin for anticoagulation (helps to avoid blood clotting on or near the valve) and maintaining appropriate levels of warfarin can be hard to manage. Some patients may be too responsive to warfarin or not responsive enough. Some patients are allergic to warfarin. A larger number of patients have a hard time keeping warfarin control because of how warfarin interacts with other drugs or certain foods. Another reason people don’t want to take warfarin is because of the need for frequent blood testing. Thus, some patients choose tissue valves over mechanical valves even though studies show the outcomes are worse because the patients do not want to have to take warfarin because it can be hard to manage.
    • Male or female at least 18 years of age at the time of giving informed consent.
    • Participants currently receiving warfarin anticoagulation and who are able to receive warfarin with a target INR 2.0 to 3.0.

    This study is enrolling patients who are about to have a heart transplant. After transplantation, or any other major surgery, there will be inflammation in the body. This inflammation can contribute to rejection of the transplanted heart. In addition, the immune system (your body’s defenses to protect against disease) will be activated by the presence of the new heart. Investigators believe that a drug called tocilizumab (ACTEMRA®) might reduce or prevent inflammation and reduce the immune system’s response to the new heart, and that this would improve the long-term health of your new heart. The purpose of this research study is to see if a study drug called Actemra® (tocilizumab) will, when given with standard anti-rejection medicines, lead to better heart transplantation outcomes at 1 year after the transplant. Tocilizumab is a prescription medicine approved by the US Food and Drug Administration (FDA) to treat rheumatoid arthritis (RA) and other inflammatory diseases. Tocilizumab has not been used before to treat people who receive a heart transplant. We don’t know if it will be good for people who have a heart transplant. Tocilizumab is not approved by the FDA to treat heart transplant patients, and therefore using it in this study is considered investigational.

    This study is enrolling patients who have a diagnosis of congestive heart failure in their medical record, and is interested in determining whether one can use an automated, computer-based method to diagnose a specific cause of heart failure (“transthyretin cardiac amyloidosis”) based on other diagnoses in the medical record. Transthyretin cardiac amyloidosis is a rare disease that results from a protein in the body that becomes misfolded and starts depositing into the heart, a process known as amyloidosis. Because of these proteins getting into the heart muscle, the heart can get stiff and weak, thereby leading to congestive heart failure. Typically this form of heart disease (cardiac amyloidosis) is diagnosed late in its course and it associated with poor survival. However, there are now treatments for this disease, so earlier diagnosis is better. A machine learning (artificial intelligence)-based method to find potential patients with cardiac amyloidosis has been developed. This computer program automates finding patients who may have cardiac amyloidosis based on their other diagnoses in the electronic health record. This study seeks to validate the computer algorithm prospectively to see if it can be useful in patients to determine whether or not cardiac amyloidosis is the cause of heart failure.

    This study is enrolling patients at Northwestern Memorial Hospital who have tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) or coronavirus disease 2019 (COVID-19) and require oxygen support. Doctors at Northwestern University want to better understand if blocking a molecule in the blood, plasminogen activator inhibitor-1 (PAI-1), which is linked with inflammation, pulmonary disease and clotting, can improve outcomes for people with COVID-19. The medicine being used in this study, TM5614, is an investigational drug, which means it is not approved by the U.S. Food and Drug Administration (FDA).

    This study is enrolling patients who have an irregular heartbeat(arrhythmia) and have been scheduled for an ablation (procedure that destroys small area of heart tissue that causes an arrhythmia) to treat the arrhythmia. This irregular heart rhythm is also known as atrial fibrillation, or AF. There are several forms of AF. Persistent AF is when the irregular heart rate become continuous and lasts for at least 7-days but no more than 12 months. Once it has lasted continuously for more than one-year it is referred to as long-standing persistent AF. AF may be treated with medicines, electrical shock(cardioversion), or the ablation for which the patient has been scheduled. The purpose of this study is to demonstrate the safety and effectiveness of the Adagio Medical iCLAS System when used in the treatment of persistent atrial fibrillation. The device is a new type of ablation technology that uses very low freezing temperatures.

    This study is enrolling patients at Northwestern Memorial Hospital with a history of heart failure with preserved ejection fraction and diabetes mellitus. Doctors at Northwestern University want to better understand if combining three different types of medicines at low doses into one pill can simplify and improve treatment for people who are prone to retaining fluid because of a condition called heart failure with preserved ejection fraction. Specifically, this is the most common type of heart failure and occurs with a normal ejection fraction or squeezing capacity of the heart muscle. Because patients with diabetes mellitus and heart failure with preserved ejection fraction are more likely to retain fluid, we are studying people with both of these conditions. The medicines being used in this study - bumetanide, eplerenone, and dapagliflozin- are all approved by the Food and Drug Administration (FDA) and commonly prescribed by medical providers for heart failure with preserved ejection fraction (bumetanide and eplerenone) and diabetes mellitus (dapagliflozin). In this study, they will be combined into one pill, a “Low-Dose Triple Polydiuretic Therapy” or “LDTPT” to see if LDTPT leads to reduction in NT-proBNP, a hormone which is high among persons who have heart failure with preserved ejection fraction. The (FDA) has not approved the LDTPT pill for general use and its use in this study is experimental.

    This study is enrolling patients diagnosed with a form of heart failure that is characterized by a weakened heart muscle that appears to be pumping in a normal manner. This condition is called “heart failure with preserved ejection fraction” or HFpEF. Patient's heart failure is not responding well to the medicine that their doctor has prescribed, and they continue to have symptoms. Their doctor has determined that the health problems and symptoms they are experiencing may be due to a significant increase in the pressure of one of the chambers in the heart. This pressure build-up causes a variety of symptoms, including tiredness, difficulty breathing, and reduced ability to exercise/walk. This study will evaluate a new device (the “Axon System”) designed to reduce the build-up of pressure described above. The relief of this pressure may reduce some or all of the symptoms they are experiencing. The Axon System is not yet approved by the US Food and Drug Administration (FDA) and is considered investigational.

    The greater splanchnic nerve (“GSN”) is a nerve that connects to the intestines, liver and spleen. It also communicates with the brain and controls a large volume of the venous blood flow in the body. Researchers believe that in patients with HFpEF the GSN is over-stimulated which causes the body to move more blood into the central veins and lungs. This results in the symptoms experienced, such as shortness of breath with exercise and swelling in the arms or legs. Researchers at Axon decided to study if altering the function of the GSN can improve the symptoms of patients with HFpEF. The purpose of this study is to evaluate the safety and potential benefits of ablation (destruction) of one side of the GSN in patients with HFpEF. Ablation of the GSN is performed for other types of conditions, usually for pain relief in patients with abdominal cancer or chronic pain.

    This study is enrolling patients in whom the Amulet device could be beneficial in reducing the risk of ischemic stroke due to non-valvular atrial fibrillation (AF). The purpose of this research study is to compare the safety and effectiveness of the Amulet device compared to non-vitamin K antagonist oral anticoagulants (NOACs) for ischemic stroke risk reduction. NOACs are a class or type of drugs taken daily, which thin the blood to reduce blood clots and the risk of an ischemic stroke. An ischemic stroke occurs when a small clot prevents blood and oxygen from reaching part of the brain. While NOACs are effective in preventing blood clots and ischemic stroke, thinning of the blood can increase the risk for bleeding events. The Amulet device is intended to be permanently implanted within the LAA. The LAA is a small pouch attached to the upper left chamber of the heart, the left atrium. In patients with non-valvular atrial fibrillation, clots can form in the LAA and travel to the brain, sometimes causing an ischemic stroke. The Amulet device is designed to seal off the LAA from blood flow, preventing clots from leaving the LAA and traveling to the brain. This is accomplished without the need for NOACs or warfarin in most cases.

    This study is enrolling patients who are a registered as a heart transplant candidate and whose doctor has determined that they may be suitable to take part in the continued access study of the TransMedics® Organ Care System (OCS™) System, a new way to preserve, monitor and assess donor hearts during the time between removal from the donor and the transplant operation. This study is a continuation of the OCS Heart DCD trial. The purpose of this study is to continue to evaluate whether the OCS Heart System may be used to preserve hearts obtained from donors after circulatory death (DCD) and to evaluate whether these DCD hearts may be successfully transplanted while the OCS Heart DCD trial data are provided to and under review at FDA . Currently, in the U.S., heart donation occurs after a person has been declared brain dead and is called a donor after brain death (DBD). In these patients, the heart continues to beat and pump blood throughout the body. After life support is withdrawn, organs are retrieved immediately for transplantation.
