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

This study tests whether covered stents are better than bare metal stents for people with narrowed kidney arteries caused by atherosclerosis. About 150 participants will be randomly assigned to one stent type and followed for 12 months to see changes in kidney function and blood …

This study looks at people with narrowed kidney arteries and high blood pressure. It uses a special pressure measurement (FFR) to decide who gets a stent and who gets only medication. The goal is to see which approach better protects kidney function and controls blood pressure ov…

This large study tests whether closing a common heart hole (atrial septal defect) using only ultrasound guidance and special tools is as good as the standard X-ray method. The goal is to avoid radiation and contrast dye risks, such as cancer and kidney injury. About 666 participa…

This study tests a new way to replace a leaky heart valve (aortic regurgitation) without using X-rays or contrast dye, which can harm the kidneys. Instead, doctors will use only ultrasound (echocardiography) to guide the procedure. The goal is to see if this approach is safe and …

This study tests a new way to replace the aortic valve in people with a leaky heart valve (aortic regurgitation) without using X-rays or contrast dye. Instead, doctors will rely on ultrasound (TEE) to guide the procedure. The goal is to see if this approach is safe and effective,…

This study watches 210 older adults (60+) having heart surgery to see if the anesthesia drug remimazolam affects their thinking and memory afterward. Participants answer questionnaires about confusion and mental function. The goal is to learn, not to test a new treatment.

This study looks at how a low dose of colchicine, an anti-inflammatory drug, changes proteins in the blood of people with coronary heart disease and high inflammation. Researchers will compare protein levels before and after one month of treatment in 176 patients. The goal is to …

This study will follow 5,000 adults undergoing heart surgery to develop a way to predict acute kidney injury (AKI) early. Researchers will collect blood and urine samples along with clinical data to build a warning model. The goal is to identify high-risk patients sooner and impr…
