Congenital left ventricular wall defects presenting with ventricular arrhythmias: A case series

Congenital left ventricular aneurysms (LVA) and left ventricular diverticula (LVD) are ventricular wall defects without a known genetic cause. LVA are characterized by akinetic or dyskinetic walls composed of fibrous tissue, whereas LVD contain 3 intact myocardial layers with preserved contractility.1 Estimated prevalence is 0.3% for LVA and 0.4% for LVD,2 which may be an underestimation, since many individuals with LVA/LVD are asymptomatic and routine imaging modalities such as transthoracic echocardiography (TTE) are insensitive in detection.
