Left ventricular (LV) diverticulum is a relatively rare condition, and it is important to differentiate it from pseudoaneurysm. The increasing use of noninvasive imaging modalities can help to demonstrate different types of ventricular outpouching structures. We report a case of congenital LV diverticulum that is much larger than the usual size and is diagnosed with tissue Doppler echocardiography and cardiac magnetic resonance imaging. Although a ventricular diverticulum is mostly asymptomatic, in the case of this particular patient, it has become complicated with infective endocarditis.<Learning objective: Congenital ventricular diverticulum is a rare finding and can be diagnosed with noninvasive imaging modalities such as tissue Doppler echocardiography and cardiac magnetic resonance imaging rather than surgery. Although congenital ventricular diverticulum is asymptomatic in most cases, infective endocarditis is a known complication.>
