title: [A case of emergency surgery for acute mitral regurgitation due to complete papillary muscle rupture as a severe form of reperfusion injury: report of a case].
abstract: Complete rupture of a papillary muscle following acute myocardial infarction is a severe complication associate with acute left ventricular failure and pulmonary edema. Since the introduction of acute percutaneous transluminal coronary angioplasty (PTCA) in the management of acute myocardial infarction, the frequency of this complication has further decreased. We described a patient who had acute mitral regurgitation due to complete rupture of papillary muscle rupture after successful coronary intervention. Transesophageal echocardiography demonstrated severe mitral regurgitation and the ruptured papillary muscle. At operation, posteriol papillary muscle was found to be totally ruptured. Mitral valve replacement was performed. Postoperative course was uneventful, with 2 days of IABP and 5 days of ventilator support.
