Recurrent mitral regurgitation after surgical repair can pose complex treatment decisions when redo surgery is high risk and prior repair alters anatomy.
2

Transcatheter electrosurgery can modify, traverse, or lacerate cardiac tissue; LAMPOON lacerates the anterior mitral leaflet to reduce outflow tract obstruction risk.
3

In a postrepair case, combined LAMPOON and Alfieri stitch laceration enabled transcatheter valve deployment despite a long anterior leaflet and prior stitch.
4

The team used preemptive extracorporeal membrane oxygenation before leaflet modification; the patient was decannulated within days and remained well at follow-up.
5

Atlantic Health Morristown performs 30 to 40 leaflet modification procedures annually across the aortic, mitral, and tricuspid valves.
