Summary:A 32-year-old male was admitted with dyspnea Severe dyspnea and hypoxemia developed the next day and blood examination indicated acute myocardial infarction. Echocardiogram revealed massive mitral regurgitation with prolapse of the anterior mitral leaflet due to rupture in the papillary muscle. Percutaneous coronary intervention for total occlusion in the right coronary artery was successfully performed, but progressive heart failure continued to develop. Surgery for the papillary muscle rupture was performed on the 3rd day. Complete head rupture of the anterior papillary muscle was found and the mitral valve was replaced with a prosthetic valve (St. Jude Medical valve: #31). Pathological findings showed necrosis in the papillary muscle with inflammatory changes. The postoperative course was uneventful and the patient was discharged on the 43rd day after surgery.
