Repeated Systolic Anterior Motion of the Mitral Valve After Double Outlet Right Ventricle Repair

TL;DR

This paper describes a rare case of repeated systolic anterior motion of the mitral valve after a specific heart surgery, highlighting possible causes like drug use or tachycardia.

Contribution

The paper presents a rare complication after double outlet right ventricle repair and identifies potential functional causes for systolic anterior motion.

Findings

Repeated systolic anterior motion occurred after double outlet right ventricle repair.

Functional factors like inotropic drugs or tachycardia may cause mitral valve issues post-surgery.

Left ventricular outflow tract obstruction is not always necessary for this complication.

Abstract

We herein report a rare case of double outlet right ventricle repair complicated by repeated systolic anterior motion of the mitral valve after weaning from cardiopulmonary bypass and postoperatively. Even in patients without obvious preoperative left ventricular outflow tract obstruction, systolic anterior motion and mitral regurgitation may still occur from functional factors, such as intraoperative or postoperative inotropic drug use, tachycardia, or intraventricular volume loss in patients with severe ventricular septal hypertrophy and left ventricular hypertrophy.
