Dragonfly device study for leaking mitral valve in high-risk patients
Part of Heart & circulation clinical trials.
This trial tests the safety and effectiveness of a heart procedure that repairs a leaking mitral valve through thin tubes, using the Dragonfly system. It’s for people who have significant mitral valve leak symptoms but are considered high risk for open-heart surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- Your echocardiogram (ultrasound of the heart) shows moderate-to-severe to severe mitral valve leak (grade 3+ to 4+).
- You feel symptoms with everyday activity (NYHA class II, III, or IV).
- Your heart pumping strength is reduced but not too low (left ventricular ejection fraction is at least 20%).
- Your heart anatomy is suitable for a tube-based “edge-to-edge” mitral repair with the Dragonfly device.
- You are considered high risk for surgery (for example, high STS risk score or major frailty/organ issues).

Other trials that look related to this one.
This trial studies whether a device called GeminiOne can safely and effectively repair a leaky mitral valve using a catheter-based “clip” technique. It may help patients who have moderate-to-severe or severe valve leakage but are considered too high-risk for open surgery.
This trial tests a catheter-based procedure (putting a small device through blood vessels) to repair a leaking mitral valve caused by heart muscle problems. It aims to reduce symptoms and improve heart function and safety in people who are still having heart failure symptoms despite standard treatment.
This trial tests a device called the Dragonfly system to fix a leaky mitral valve caused by heart muscle problems. It may help people with symptoms like shortness of breath or fatigue from this condition.
This trial studies a new catheter-based valve replacement system for people with moderate to severe, or severe, mitral valve regurgitation (a leaky mitral valve). It aims to check whether the procedure is safe and can improve heart function compared with expected care.
This trial tests a new device (DragonFly M2) to fix a leaky mitral valve. It's for people with moderate to severe or severe chronic mitral regurgitation who may be able to have the procedure done through a vein in the leg.
This study tests a catheter-based procedure to treat a leaky mitral valve (either FMR or DMR, depending on the group you’re in). It may help reduce symptoms and improve heart function in people who are sick from valve leakage but are able to undergo this specific approach.
