[Superimposed infective endocarditis at anterior mitral leaflet in a patient with prolapsed posterior leaflet: report of a case treated with valvuloplasty].

A 64-year-old male patient was referred to our hospital for massive mitral regurgitation after infective endocarditis. Echocardiography revealed vegetation on the atrial surface of the midst of the anterior mitral leaflet. At operation it was found that the anterior leaflet was perforated due to infection, and the posterior leaflet was prolapsed resulting from elongated chordae. Anterior leaflet was patched with autologous pericardium, and posterior leaflet was repaired with rectangler resection. An autologous pericardial strip was sutured to posterior mitral annulus. The patient survived the operation without complication.
