Multiplane Transesophageal Echocardiographic Description of a Complete Papillary Muscle Rupture during Acute Myocardial Infarction

Abstract

The complete rupture of a papillary muscle is a relatively rare complication of acute myocardial infarction and is generally considered to be rapidly fatal. We describe the multiplane transesophageal echocardiography features of a completely ruptured anterolateral papillary muscle complicating acute non-Q wave lateral myocardial infarction.
