[Mitral valvuloplasty utilizing a posterior leaflet patch for healed infective endocarditis; report of a case].

A 63-year-old man was diagnosed as having grade IV mitral regurgitation (MR). Intraoperative examination revealed perforation (13x7 mm) of the anterior mitral leaflet (AML) and prolapse of the posterior mitral leaflet (PML). The prolapsing part of the PML was resected as a rectangle and the AML perforation was covered with this resected PML patch. A Carpentier-Edwards rigid ring (30 mm) was used to secure the mitral valve annulus after suturing the PML. The patient had an uneventful course after surgery and postoperative echocardiography showed no regurgitation.
