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 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. 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 320 people in the entire study nationally..

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.

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.

    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.

    The purpose of this researchstudy is to compare health outcomes of patients diagnosed with Primary MR whohave their MV repaired with open heart surgery, which is the current standardtreatment, to patients who have their Mitral Valve repaired with the MitraClipSystem. The MitraClip System uses a less invasive procedure to repair themitral valve.

    Subjects are asked to participatein this Study because they have moderate-to-severe or severe MR and it has beendetermined to have symptoms due to heart failure despite being treated with currentlyavailable therapies. MR occurs when the leaflets of your mitral valve do notclose properly causing blood to leak backward with each heartbeat. Since someof the blood leaks backward, the heart needs to pump more blood with each beatto push the same amount of blood forward.

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

    • Subject hassevere (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
