Aortic valve insufficiency

This early study is testing a new device called the DurAVR™ THV System, which is a replacement heart valve placed through a small tube in the leg (TAVI procedure). The study includes 40 people with severe aortic stenosis or a failed surgical valve. The main goal is to see if the …

This study is testing a new heart valve device (JenaValve Trilogy) placed through a tube in an artery, without open surgery. It is for 50 adults who have a mechanical heart pump (LVAD) and also a leaky aortic valve that makes the pump work less effectively. The goal is to see if …

This study tests whether injecting botulinum toxin (Botox) into fat pads around the heart's veins during cardiac surgery can prevent atrial fibrillation (AFib), a common and serious complication. About 220 adults undergoing heart surgery will receive either Botox or a placebo inj…

This study is testing a new surgical heart valve (Model 400) in over 1,300 people with aortic valve disease. The valve is designed to replace the damaged aortic valve and improve blood flow. Researchers are checking how safe the valve is and how well it works over one year, looki…

This study compares two types of TAVI valves (Edwards and CoreValve Evolut) in 102 people with small, failing surgical aortic valves. The goal is to see which valve leads to fewer problems like high pressure or leakage after the procedure. Results could guide doctors in choosing …

This study compares two ways to replace a narrowed heart valve in elderly patients (65+) who have a small valve opening. One method is less invasive (TAVR, through a tube in an artery), the other is open-heart surgery. The goal is to see which approach gives better blood flow and…

This study tests whether using 3D simulation before a minimally invasive aortic valve replacement helps doctors place the valve more accurately. It involves 354 adults aged 65 and older with severe aortic regurgitation (a leaky heart valve). Participants are randomly assigned to …

This study tests a special plug device to close leaks that can form around surgically implanted heart valves. These leaks can cause serious problems like heart failure or anemia. The procedure is done through a catheter, avoiding the need for another open-heart surgery. The study…

This study collects tissue samples from 1,000 people having heart valve surgery to find genetic causes of calcific aortic valve disease. Researchers will compare normal and diseased tissue to understand why the disease develops. Participants must be at least 20 years old and have…

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 looks at whether a special MRI scan can detect early scarring in the heart muscle of people with leaky heart valves. The goal is to find a way to predict when the heart might start to fail, so doctors can decide on surgery sooner. About 316 adults with moderate to seve…
