This study is testing whether doctors can safely replace a narrowed heart valve using only ultrasound imaging to guide them, instead of X-rays. Researchers will perform this procedure on 20 patients with severe aortic stenosis, where the heart's main valve has become dangerously …

This study is testing whether a special anesthesia plan focused on protecting the brain can reduce hidden strokes and thinking problems after heart surgery. Researchers will compare this new plan to standard care in over 900 older adults having planned heart surgery. The goal is …

This study is testing whether taking oral capsules containing healthy donor stool (fecal microbiota transplantation) can help control aging-related decline in older adults. Researchers will enroll 210 people aged 70-85 to receive either the treatment or a placebo, then track chan…

This study compares a new biodegradable heart implant to a traditional metal one for treating migraines in people with a small heart hole called PFO. Researchers want to see if the dissolving implant reduces migraine days per month better than the permanent metal version, with fe…

This study aims to find the safest blood thinner approach for patients who have undergone a minimally invasive heart valve repair procedure. Researchers will compare different medication strategies in over 1,000 patients to determine which approach best balances the risk of bleed…

This study is testing whether a minimally invasive procedure is as good as or better than standard pills for treating a hormone disorder that causes high blood pressure. Researchers will compare a procedure that blocks tiny blood vessels in the adrenal glands with the usual medic…

This study aims to find the best blood thinner strategy for patients who have undergone a minimally invasive heart valve repair and also need long-term blood thinners. Researchers will compare different approaches to balance the risks of dangerous bleeding against the risks of st…

This study is trying to find the best time for patients to start walking after a leg artery procedure. Researchers will test different waiting times after using a ProGlide device to close the artery puncture. The goal is to help patients get moving sooner while avoiding complicat…

This study looks back at existing heart MRI scans from 1,000 patients with coronary artery disease or previous heart attacks. Researchers want to see if specific measurements from these detailed scans can help predict who might experience serious heart problems in the future, lik…

This study aims to see if a special heart MRI scan can help doctors better predict which patients will benefit from implanted heart devices like pacemakers and defibrillators. Researchers will look at MRI scans from 1,500 adults who are already scheduled to get a device, then tra…

This study is testing whether advanced heart imaging techniques can improve how doctors diagnose and predict risks for rare heart muscle diseases. Researchers will use special heart scans to create detailed pictures of participants' hearts, looking for patterns that might help id…

This study aims to understand how specific features seen on heart MRI scans can help predict the future health risks for people with non-dilated left ventricular cardiomyopathy (NDLVC), a type of heart muscle disease. Researchers will look back at the medical records and MRI scan…

This study aims to create a detailed picture of how heart tissue appears on a specific type of MRI scan (called T1 mapping) in people with various heart conditions. Researchers will scan 2,000 adult patients who already have a diagnosed heart disease to establish normal measureme…

This large national study is investigating a specialized vein sampling procedure used to diagnose a hormone-related cause of high blood pressure. It will follow 5,000 patients to see if using this test to guide treatment leads to better long-term heart health and blood pressure c…
