Mitral valve prolapse

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 whether a bedside device called Quantra can help doctors decide when to give blood transfusions during complex heart surgery. The device measures how well a patient's blood clots in real time. Researchers hope this will reduce the number of blood products (like r…

This study follows 280 people with mitral valve prolapse over 3 years to see if heart MRI scans and blood tests can predict who will develop dangerous heart rhythms or heart muscle changes. Participants undergo MRI, blood draws, and heart monitoring. The goal is to find early war…

This study looks at whether using a cardiac MRI (CMR) instead of the usual ultrasound helps doctors make better decisions about heart valve surgery for people with severe mitral regurgitation (a leaky heart valve). About 260 adults with no symptoms but severe leakage will be foll…

This study was designed to see if early mobilization and a simple bottle-based breathing device (Bottle-P.E.P.) could improve breathing and physical function in people recovering from heart valve surgery. The trial was withdrawn before enrolling any participants, so no results ar…

This study tests a new sensor worn on the skin that measures lactate levels without needles. It involves 20 adults recovering from heart bypass or valve surgery. The goal is to see if the sensor works as well as standard blood tests, which could make monitoring more comfortable a…

This study compares two methods for deciding which blocked heart arteries need bypass during valve surgery. The standard method uses angiography (X-ray dye), while the new method uses a computer calculation called QFR. About 792 patients will be randomly assigned to one method, a…
