Mitral valve disorder

This study tests a new device called Tendyne, which is a replacement heart valve placed through a tube in the blood vessels, avoiding open-heart surgery. It is for people with a leaky mitral valve (mitral regurgitation) who are too high-risk for traditional surgery. The trial com…

This early study tested a new device called the Millipede ring, which is delivered through a catheter to tighten the mitral valve in people with functional mitral regurgitation (a leaky valve). Only 4 participants were enrolled to see if the procedure is safe and technically poss…

This trial tests a new device called the Edwards SAPIEN M3 System for people with severe mitral regurgitation, a condition where a heart valve leaks blood backward. The device is placed using a thin tube threaded through blood vessels, avoiding open-heart surgery. The study inclu…

This study compares two devices—the Edwards PASCAL and the Abbott MitraClip—that repair leaky mitral heart valves without open-heart surgery. About 1,200 people with severe mitral regurgitation who are too high-risk for surgery are being randomly assigned to one device. The goal …

This study compares two surgical techniques to fix a leaky mitral valve caused by degenerative disease. One method replaces the tiny chords that support the valve, while the other moves existing chords to a better position. The trial will follow 64 adults for one year after surge…

This study tests a new device that repairs leaky mitral heart valves without stopping the heart or using a heart-lung machine, compared to standard open surgery. About 585 people with moderate to severe mitral regurgitation will take part. The goal is to see if the device is safe…

This study tests a new device called the Cardiovalve, which is threaded through a blood vessel in the leg to fix a leaky mitral valve without open-heart surgery. It includes 30 people with severe mitral regurgitation who are too high-risk for traditional surgery. The goal is to s…

This pilot study tests whether drinking tart cherry concentrate for three days before heart valve surgery can reduce the risk of post-operative atrial fibrillation (an irregular heartbeat). The study involves 50 adults aged 50-79 who are in normal heart rhythm before surgery. Res…

This study tests a less invasive way to replace a failing mitral valve in the heart. About 53 people who already have a surgical valve that is not working well will receive a new valve placed inside the old one using a thin tube. The goal is to see if this procedure is safe and h…

This study aimed to see if freezing certain nerves during minimally invasive heart surgery could lower pain afterward. It planned to enroll adults having mitral valve or atrial septal defect repair. However, the trial was withdrawn before any participants were enrolled, so no dat…
