Introduction
Congenital left ventricular diverticulum (CLVD) consists of an outpouching of endocardium, myocardium, and pericardium, which often presents as a projection from the ventricular free wall, with a narrow neck connecting the cavity to the ventricle proper [1]. Due to its composition of normal cardiac tissue, as compared to a congenital left ventricular aneurysm (CLVA), the diverticulum contracts synchronously with the remainder of the ventricle. Thromboembolic events, ventricular arrhythmias, heart failure, and free wall rupture have been documented to occur. Due to its low overall prevalence between 0.02% to 0.76% [2, 3, 4], and variability in presentation, a standardized treatment paradigm has yet to be delineated. We report the successful repair of a congenital left ventricular diverticulum using a two patch technique.
