Description
Xinping Lin and co-authors report a case from 2026 of clip repair for a leaky mitral valve in a 90-year-old man. His mixed leak combined a flailing segment with atrial-driven widening, and his valve opening measured only 4.09 square centimeters, leaving little room before clips would narrow the passage dangerously.
Surgical risk was prohibitive, so the heart team used the DragonFly edge-to-edge system under ultrasound guidance. Two clips went in sequence, the second closed with a stepless self-locking method that fine-tunes grip against pressure buildup. Leakage fell from the worst grade to mild, the final gradient stayed at 4 millimeters of mercury, and his breathing and function improved during follow-up.
