Mitral valve repair for isolated prolapse of the anterior leaflet: an 11-year follow-up.

Objective: Mitral valve insufficiency (MVI) because of involvement of the anterior mitral leaflet may pose additional risks for late outcome after mitral valve repair, because of more complex techniques. We retrospectively reviewed our experience in patients operated on for isolated anterior mitral leaflet prolapse approached by various techniques.

Methods: Between 1986 and 1997, 616 patients underwent mitral valve repair at our Institution.
