True diverticulum of the left ventricle is very rarely seen in adults: the condition typically occurs in children and can be associated with other anatomic defects that involve the thoracoabdominal midline. Left ventricular diverticulum, which is usually asymptomatic and typically discovered incidentally, can pose a substantial challenge to the surgeon.Herein, we report the case of a 46-year-old man who presented with worsening exertional angina and ST-segment elevation in the inferior electrocardiographic leads. After a stent was deployed in the patient's occluded right coronary artery, left ventriculography revealed outward pouching of the left ventricular inferior wall, suggesting an aneurysm or a contained free-wall rupture. Transesophageal echocardiography showed a sizable defect and a possible intracavitary thrombus. The presumptive diagnosis was a postinfarction subacute pseudoaneurysm of the left ventricle. However, during surgery, we saw no clots, intrapericardial blood accumulation, or perforation. A localized area of thinned muscle in the region of the posterior descending coronary artery was consistent with a ventricular diverticulum. The left ventricular epicardial surface was reinforced with a small bovine pericardial patch. The patient's recovery was uneventful. We discuss the forms of congenital left ventricular diverticulum and offer considerations regarding differential diagnosis.
