Severe mitral regurgitation following partial rupture of papillary muscle: The role of intraoperative transesophageal echocardiography

Abstract

Papillary muscle rupture (PMR) is an uncommon mechanical complication of myocardial infarction which warrants timely diagnosis and urgent surgical intervention to maximize survival chances. Echocardiography is an essential diagnostic tool, whereas transesophageal echocardiography can provide accurate diagnosis and guide decision-making. We hereby present the case of a patient with partial PMR that presented for cardiac surgery in our institution, with the respective intraoperative echocardiographic findings.
