The purpose of this study is to evaluate the safety and effectiveness of the ACURATE TAVR system in patient with severe aortic valve stenosis who are identified as an appropriate candidate for the TAVR procedure.

We are doing this study to look at the effects of CagriSema on cardiovascular events (for example heart attack and stroke) in people living with obesity and cardiovascular disease.

This study is meant to better understand the prevalence of overweight and obesity in patients who have a history of cardiovascular disease.

The purpose of this study is to determine if a new medication is effective at treating cardiac amyloidosis.

This study is testing a medication called ziltivekmab to see if it can help people with heart failure.

This study is testing eplontersen as a treatment for Cardiac Amyloidosis.

The purpose of this study is to survey patients on their experiences being treated for Severe Aortic Stenosis

The purpose of this study is to define patient populations who may recover left atrial mechanical function rapidly (<24 hours) following cardioversion. Defining these characteristics will help us weigh the risks and benefits of anticoagulation following cardioversion.

The study will look at the effectiveness of the Aortix system, a support device for chronic heart failure patients, at treating patients with heart failure.

This study is comparing two ways of treating Atrial Fibrillation (AF). Patients will either take continuous anticoagulation medications, or they will wear AF-sensing smartwatches and take anticoagulation medications for 30 days after an AF event.
