This study is tracking 150 people who receive a new type of heart valve (SAPIEN 3 Ultra RESILIA) to see how well it works over time. The valve has special features to prevent calcium buildup and improve durability. Researchers will use echocardiograms to measure valve function an…

This study looks at whether a specific antibody in the blood can help diagnose and predict the course of a rare, life-threatening heart condition called short-coupled ventricular fibrillation (SCVF). Researchers will test 300 adults with SCVF for these antibodies and study how th…

This study compares two methods—ultrasound (echocardiography) versus direct pressure measurements (catheterization)—to guide additional balloon inflation after valve-in-valve TAVR. About 310 people with failing surgical aortic valves will be randomly assigned to one method. The g…

This trial compares conscious sedation versus general anesthesia for a lung biopsy procedure called pEBUS, used to diagnose lung nodules. About 306 adults with peripheral lung lesions will be randomly assigned to one of the two sedation methods. The goal is to see which approach …
