Summary

This study tests a device called DragonFly that clips a leaky mitral valve in the heart. It is for people with moderate-to-severe or severe mitral regurgitation who still have symptoms despite standard treatment. About 148 adults will be randomly assigned to get the clip or continue usual care. The goal is to see if the clip improves survival, reduces hospital stays, and eases symptoms.
