    Abstract:
    Mitral regurgitation (MR) due to rupture of the papillary muscle is one of the most serious complications of acute myocardial infarction (AMI) as well as ventricular septal perforation and ventricular free wall rupture. We experienced a case of complete rupture of the anterior papillary muscle. A 68-year-old man experienced an episode of dyspnea. Electrocardiographic findings were consistent with postero-lateral infarction. Massive MR is present on color Doppler imaging. He was transferred to our hospital for urgent operative indication because of papillary muscle rupture due to AMI. Six hours after the onset, the operation was performed with intra-aortic balloon pump in place. The anterior papillary muscle was ruptured completely in the mid portion. He underwent a mitral valve replacement with a SJM prosthetic valve. There is a few cases with successful urgent surgery for a complete rupture of anterior papillary muscle.
