Abstract

Intraoperative 2- and 3-Dimensional Transesophageal Echocardiographic Guidance for Cardiovascular Surgery in a Patient with a Single Papillary Muscle "Parachute Valve"

Highlights

Parachute Mitral Valve (PMV) is a rare congenital cardiac defect characterized by focalized attachment of the chordae tendinae of both leaflets to a single papillary muscle [1]
A 55-year-old white male with new onset of atrial fibrillation, left hemiparesis, and a subsequent myocardial infarction presented for elective Atrioventricular Septal Defects (AVSD) repair and coronary artery bypass graft
Most patients present during infancy with mitral stenosis of varying severity, or, less frequently, mitral regurgitation [10]

Summary

Introduction

Parachute Mitral Valve (PMV) is a rare congenital cardiac defect characterized by focalized attachment of the chordae tendinae of both leaflets to a single papillary muscle [1]. It may occur as an isolated lesion or part of a Shone’s anomaly in infants and young children [2]. Not much is known about PMV in adults [3]. A combination of 2- (2D) and 3-dimensional (3D) transesophageal echocardiography (TEE) is essential to guide these complex surgical procedures in children and, more rarely, in adults [5]
