This study will check if a special heart valve replacement (SAPIEN 3) works well and is safe for people with a rare type of aortic valve disease called Type-0 bicuspid valve. About 170 people in China will take part. The goal is to see if the valve helps reduce death, stroke, or …

This study tests a new method for replacing 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 (echocardiography) to guide the procedure. This approach aims to avoid radiation expo…

This study tests a new way to replace a leaky heart valve (aortic regurgitation) using only ultrasound guidance, avoiding radiation and contrast dye. The approach aims to be safer for patients with kidney problems or dye allergies. Thirty adults with severe valve leakage will be …

This study looks at 300 people with narrowed kidney arteries and high blood pressure. It tests whether using a special pressure measurement (FFR) to decide on placing a stent works better than medication alone. The goal is to see if this approach improves kidney function and bloo…

This study tests whether covered stents work better than bare metal stents for people with narrowed kidney arteries caused by plaque buildup. About 150 participants will be randomly assigned to receive one of the two stents and will be followed for 12 months. The goal is to see w…

This study tests a new method to close a common heart hole (atrial septal defect) using only ultrasound guidance, avoiding X-rays and contrast dyes. About 666 people will be randomly assigned to either the new ultrasound method or the standard X-ray method. The goal is to see if …

This study enrolls 5,000 adults having heart surgery to develop a way to predict kidney injury early. Researchers collect medical data and blood/urine samples before, during, and after surgery. Participants receive standard care and are followed for up to 2 years. The goal is to …

This observational study looks at how the anesthetic remimazolam affects brain function in older adults after heart surgery. Researchers will track confusion and memory problems in 210 patients aged 60 and older. The goal is to see if this drug reduces the risk of postoperative d…

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 who have high inflammation. Researchers will compare blood samples from 176 patients before and after one month of treatment to find ne…
