Congenital left ventricular diverticulum diagnosed by 64-detector CT imaging.

ABSTRACT

A congenital left ventricular (LV) diverticulum or aneurysm is a rare cardiac malformation. It is a developmental anomaly that occurs during embryogenesis. Most congenital LV aneurysms and diverticula are asymptomatic or may cause systemic embolization, heart failure, valvular regurgitation, ventricular wall rupture, ventricular tachycardia or sudden cardiac death. Diagnosis is established by imaging studies such as echocardiography, magnetic resonance imaging or left ventriculography, visualizing the structural changes. We report the case of a 28-year-old male referred for the evaluation of atypical chest pain who was found to have an LV diverticulum affecting the inferoposterior wall of his LV.
