Triangular resection of the anterior leaflet for repair of the mitral valve.

Isolated anterior mitral leaflet prolapse, unlike posterior prolapse, is a difficult lesion to repair and may become a demanding surgical procedure. We report our experience with a technique of a triangular resection of the anterior leaflet to repair isolated segmental anterior leaflet prolapse in 18 patients. This technique simplifies the repair procedure and is a safe and rapid procedure which allows excellent results.
