This study looks at the best blood-thinning medicine after a minimally invasive heart valve repair for mitral regurgitation, a common heart condition. About 1,032 participants will be randomly assigned to take either aspirin alone or aspirin plus clopidogrel. The goal is to see w…

This study looks at 880 people who had a minimally invasive heart valve repair and also need long-term blood thinners. It compares taking just one blood thinner (rivaroxaban) versus taking two (rivaroxaban plus clopidogrel) to see which causes fewer bleeding problems over one yea…

This study tests a less invasive method to replace a narrowed heart valve in 20 people with severe aortic stenosis. Instead of using X-rays, doctors will guide the procedure using only ultrasound, which may reduce radiation exposure. The goal is to see if this approach is safe an…

This study tests a procedure called superselective adrenal artery embolization (SAAE) against the standard pill spironolactone for people with idiopathic hyperaldosteronism, a condition that causes high blood pressure. About 172 participants will be randomly assigned to either th…

This study is testing whether taking fecal microbiota transplants (FMT) in capsule form can reduce frailty and improve overall health in people aged 70-85. The researchers believe that restoring a healthy balance of gut bacteria may slow aging and lower the risk of age-related di…

This study tests whether a specific set of anesthesia targets, called NeuroFirst, can reduce silent brain injury and thinking problems in older adults having heart surgery. About 900 patients aged 60 and older will be randomly assigned to either the NeuroFirst approach or standar…

This study tests if a new biodegradable heart implant can reduce migraine days better than a standard metal implant in people with a small hole in the heart (PFO). The new implant is designed to dissolve over time, potentially avoiding long-term complications like metal allergies…

This study looks at whether MRI scans can help predict serious heart events in people who have implanted heart devices like pacemakers or defibrillators. Researchers will scan 1,500 adults before they get their device and track their health for years. The goal is to see if MRI fi…

This study looks at how soon patients can safely walk after a leg artery procedure using a special closure device called ProGlide. Researchers will compare different waiting times in 300 people to find the best balance between quick recovery and avoiding complications like bleedi…

This study is testing advanced heart MRI scans to better diagnose and predict risks for people with rare heart muscle diseases. Researchers will scan 1000 participants to see if these new imaging methods can identify conditions like Fabry disease and cardiac amyloidosis more accu…

This study looks at whether a special heart MRI can help predict future heart attacks, strokes, or other serious heart problems in people with ischemic heart disease. Researchers will review medical records from 1,000 adults who have already had this MRI. The goal is to better un…

This study looks at a recently identified heart condition called non-dilated left ventricular cardiomyopathy (NDLVC), where the heart muscle is abnormal but not enlarged. Researchers will review medical records and heart MRI scans from 1,000 patients to find which scan features b…

This study will use cardiac MRI scans to measure heart tissue in 2000 people with various heart conditions, such as heart attacks, cardiomyopathies, and myocarditis. The goal is to create a reference map of normal and abnormal tissue values, which may help doctors diagnose diseas…

This study looks at a special blood test called adrenal venous sampling (AVS) used in people with primary aldosteronism, a condition where the adrenal glands make too much of a hormone that raises blood pressure. The goal is to see how well AVS helps doctors choose the right trea…
