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.
