title: [Mitral regurgitation due to sole punched out lesion of the mitral anterior leaflet in infective endocarditis; report of a case].
abstract: Mitral regurgitation (MR) due to only punched out lesion is extremely rare in infective endocarditis. A 31-year-old male was admitted to our hospital due to unusual cause of MR. Echocardiography showed MR due to punched out lesion of the mitral anterior leaflet, which is extremely rare. A round shape punched out lesion (about 16 mm in size) was found intraoperatively in the anterior leaflet of the mitral valve. The surface around the punched out lesion was smooth, and the leaflet displayed good movability. Neither vegetation nor calcification was found. Punched out lesion was successfully closed with autologous pericardial patch and annuloplasty was performed.
