Left ventricular pseudo-aneurysm complicating a ruptured isolated congenital diverticulum

We report a case of 41-year-old woman who presented with chest tightness and shortness of breath. Transthoracic echocardiogram (TTE) showed left ventricular (LV) pseudo-aneurysm of the inferior wall with preserved LV systolic function. Coronary angiogram was normal. Surgical repair of the pseudo-aneurysm with a pericardial patch was performed, and pathological results confirmed rupture of an isolated congenital LV diverticulum.as the most likely etiology.
