[Ventricular Pseudoaneurysm after Sutureless Repair of Postinfarction Free Wall Rupture of the Left Ventricle:Report of a Case].

ABSTRACT

We herein report a case of a left ventricular pseudoaneurysm following sutureless repair for left ventricular free wall rupture. A 78-year-old woman underwent emergency sutureless repair for left ventricular free wall rupture following acute myocardial infarction. Three months later, echocardiography revealed an aneurysm in the postero-lateral wall of the left ventricle. The ventricular aneurysm was incised during reoperation, and defect in the left ventricular wall was closed with a bovine pericardial patch. Histopathologically, the aneurysm wall did not contain any myocardium, confirming the diagnosis of pseudoaneurysm. Although sutureless repair is a simple and highly effective method for oozing-type left ventricular free wall rupture, post-procedural pseudoaneurysm can develop both in acute and chronic phases. Consequently, long-term follow-up is mandatory.
