Isolated
congenital ventricular
diverticulum or
aneurysm is rare and usually arises from the
left ventricle. The presentation of this condition is diverse. We
report three cases of isolated
congenital left ventricular
diverticula. The age range was 17-30 years.
Chest X-ray provided the earliest clinical suspicion in these three cases of a cardiac anomaly which was diagnosed by
echocardiography and confirmed by
angiocardiography. The
location of the
congenital left ventricular
diverticulum was the left ventricular apex in two cases and basal in the other. We conclude that
congenital left ventricular
diverticulum is a
disease of protean presentations. A high index of suspicion is necessary while interpreting
chest X-rays and echocardiographs to
diagnose congenital left ventricular
diverticulum. A contractile accessory chamber of the
left ventricle with a narrow
neck with or without midline defects and an
electrocardiogram without Q waves is consistent with the
diagnosis of
congenital left ventricular
diverticulum.
