This study tests whether a targeted anesthesia approach called NeuroFirst can lower the risk of silent brain damage and memory or thinking problems after heart surgery. About 912 adults aged 60 and older having elective heart surgery will be randomly assigned to receive either Ne…

This study looks at the best way to use blood thinners after a minimally invasive heart valve repair (TEER) in people with mitral regurgitation. About 1,032 participants who do not need long-term blood thinners will be randomly assigned to different anti-clotting strategies. The …

This study tests if a minimally invasive procedure (SAAE) can control high blood pressure caused by idiopathic hyperaldosteronism as well as or better than the standard medication spironolactone. About 172 people aged 15-60 with this condition will be randomly assigned to either …

This study tests whether taking fecal microbiota transplants (FMT) in capsule form can reduce frailty and improve health in people aged 70 to 85. Researchers believe that restoring gut bacteria may help with aging-related issues like memory, physical function, and inflammation. T…

This study looks at the best way to use blood thinners after a minimally invasive heart valve repair (TEER) in people with mitral regurgitation who also need long-term blood thinners for conditions like atrial fibrillation. About 880 participants will be randomly assigned to diff…

This study tests a new way to replace a narrowed heart valve (aortic stenosis) using a tube inserted through the armpit, guided only by ultrasound instead of X-rays. About 20 people with severe symptoms will be enrolled to see if this approach is safe and works well. If successfu…

This study tests whether a new biodegradable heart device can reduce migraine days better than a standard metal device in people with a common heart hole called PFO. About 400 adults aged 18-65 with frequent migraines and PFO will be randomly assigned to receive either device. Th…

This study looks at whether MRI scans can help doctors predict serious heart events in people who have implanted heart devices like pacemakers or defibrillators. Researchers will follow 1,500 adults over time to see if MRI results can identify who is at higher risk for sudden car…

This study looks at 300 people who had a leg artery procedure and uses a device called ProGlide to close the puncture site. The goal is to find the safest time to let patients get up and walk, balancing quick recovery with avoiding complications like bleeding or bruising. Results…

This study will use advanced MRI scans to measure heart tissue in 2000 adults with different heart conditions. The goal is to create a reference guide for doctors to interpret these scans more easily, and to see if a simpler scan without contrast dye can be used for diagnosis. Pa…

This study looks at a special blood test called adrenal venous sampling (AVS) to better diagnose and treat primary aldosteronism, a condition where the adrenal glands make too much of a hormone that raises blood pressure. Researchers will follow 5,000 patients to see how AVS-guid…

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 see which…

This study aims to improve how doctors diagnose and predict the course of rare heart muscle diseases (cardiomyopathies) using advanced MRI scans. Researchers will enroll 1000 people with suspected rare cardiomyopathies to test new imaging methods. The goal is to provide clearer, …

This study looks at a rare heart condition called non-dilated left ventricular cardiomyopathy (NDLVC), where the heart muscle is abnormal but not enlarged. Researchers will review past medical records and heart MRI scans from 1,000 patients to see which scan findings are linked t…
