Left ventricular inferoapical diverticulum associated with normal coronary arteries

Isolated congenital left ventricular (LV) diverticulum, which is characterized by the local failure of the ventricular muscle, is a rare cardiac abnormality with a reported prevalence of 0.4%. Clinically, it has been reported to follow an asymptomatic course in the majority of cases; however, it may cause heart failure, thrombus formation, arrhythmia, rupture or chest pain in some patients. Due to its asymptomatic course, it is difficult to diagnose an isolated LV diverticulum. Our patient was admitted to hospital with the complaint of typical chest pain and no any electrocardiogram ischemic changes. Transthoracic echocardiogram showed a diverticulum in the inferoapical wall. Coronary computed tomography angiography was performed, which revealed LV diverticulum at inferoapical region and normal coronary anatomy.
