This study tests a new way to replace the aortic heart valve in people with a leaky valve (aortic regurgitation). Instead of using X-rays and contrast dye, doctors will use only ultrasound (TEE) to guide the procedure. The goal is to see if this approach is safe and effective, es…

This study looks at how safe and effective the SAPIEN 3 heart valve is for people with a certain type of bicuspid aortic valve (Type-0) that causes narrowing. About 170 people in China will be observed after the procedure to track serious problems like death, stroke, or needing t…

This study tests a new way to replace a leaky heart valve (aortic regurgitation) using only ultrasound guidance, avoiding X-rays and contrast dye. The approach aims to be safer for people with kidney problems or dye allergies. The trial will enroll 30 adults to see if the procedu…

This study compares a new ultrasound-guided method to close a common heart hole (atrial septal defect) with the traditional X-ray-guided approach. The goal is to see if the ultrasound method works just as well while avoiding radiation and contrast dye, which can cause long-term c…

This study will enroll 5,000 adults having elective heart surgery to develop a way to predict acute kidney injury (AKI) early. Researchers will collect medical data and blood/urine samples before, during, and after surgery, then follow patients for up to 2 years. The goal is to c…

This study looks at how a low dose of colchicine changes proteins in the blood of people with coronary heart disease who have high inflammation. Researchers want to find new markers and targets for treatment. About 176 patients who had a heart procedure will take colchicine or no…

This study looks at 300 people with narrowed kidney arteries and high blood pressure to see if a pressure test called fractional flow reserve (FFR) can help doctors decide between stenting or medication alone. Participants with low FFR get a stent, while those with higher FFR are…
