Isolated congenital left ventricular diverticulum in adults.
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.
