This study compares two procedures for severe aortic valve stenosis: transcatheter aortic valve implantation (TAVI), a less invasive approach, and standard open-heart surgery. It will follow 4,000 high-risk patients for up to 24 months to see which method leads to fewer deaths, h…

This study compares two approaches for replacing an infected aortic valve: using a cryopreserved aortic homograft (a preserved human donor valve) versus conventional mechanical or tissue prosthetic valves. The goal is to see which method leads to fewer complications, such as deat…

This study looks at two surgical approaches for repairing a tear in the aorta (the main artery from the heart) in 900 patients. One approach is less invasive (root-sparing), used for higher-risk patients, while the other is more extensive (root replacement and total arch repair),…

This study compares a less invasive procedure (TEER) to standard open-heart surgery for people with severe mitral regurgitation, a condition where a heart valve doesn't close properly. About 600 adults will be randomly assigned to one of the two treatments. The main goal is to se…

This study is looking at people hospitalized for a heart attack (STEMI or NSTEMI) who undergo a procedure to open blocked heart arteries, called percutaneous coronary intervention (PCI) or angioplasty. It compares two groups: those having a standard (non-complex) PCI and those ha…

This study collects data from 1,200 patients undergoing surgery for aortic dissection, a life-threatening tear in the heart's main artery. Researchers will track death rates, strokes, and other complications to identify the safest surgical strategies. The goal is to improve outco…

This study follows 900 patients with a life-threatening tear in the aorta (type A aortic dissection) to compare outcomes between different surgical techniques. Researchers will track deaths, strokes, heart failure, and other complications within 30 days after surgery. The goal is…
