Abstract

A 70-year-old male was admitted for acute postero-inferior myocardial infarction. In cardiac catheterization one month later, there was narrowing of the distal left circumflex artery and the aneurysm of the postero-inferior wall of the left ventricle. The echocardiogram strongly suggested the pseudoaneurysm of the left ventricle. At operation, a large postero-inferior aneurysm was densely adherent to the pericardium. After cardiopulmonary bypass was established, the aorta was cross-clamped and cold cardioplegia was infused, the aneurysm was opened without excision of it. There was a 4 cm by 5 cm defect in the postero-inferior wall of the left ventricle, which communicated with the cavity of the aneurysm. The defect was closed with a patch. Pseudoaneurysm of the left ventricle was diagnosed by histological examination. The postoperative course was uneventful and he discharged on 29th day after surgery.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
