title: [Case of papillary muscle rupture diagnosed by preoperative transesophageal echocardiography].
abstract: A 46-year-old man with severe mitral regurgitation (MR) was scheduled for emergency surgery for chordae tendae repairment. Preoperative transesophageal echocardiography (TEE) revealed massive MR due to a rupture in the antero-lateral papillary muscle. We changed the operation procedure to mitral valve replacement. It is difficult to diagnose papillary muscle rupture. Therefore, we should perform TEE on the patient with acute MR of unknown origin.
