 A 73-year-old female was admitted to our hospital with fever and a swollen right leg on May 27th, 2004. The thrombophlebitis was treated with antibiotics and anticoagulants. She had exertional dyspnea (NYHA class II) and a pan-systolic murmur of Levine IV°in the mitral area. An echocardiography revealed severe mitral regurgitation (MR) due to mitral valve prolapse. Coronary angiography revealed normal coronary arteries, and left ventriculography revealed severe MR and an ejection fraction of 58%. Mitral valvuloplasty was performed. Posterior mitral valve perforation (5mm in diameter) associated with mitral valve aneurysm without chordal rupture was found intraoperatively and a healing phase of infective endocarditis was diagnosed. We report a rare case of posterior mitral valve perforation without chordal rupture.
