A Case of Double-Patch Closure for Left Ventricular Pseudo-False Aneurysm Following Subacute Myocardial Infarction / 日本心臓血管外科学会雑誌

ABSTRACT

A 65-year-old man was admitted with subacute myocardial infarction. During medical treatment, the patient lost consciousness as a result of an atrioventricular block and underwent an operation for an emergency percutaneous coronary intervention in the right coronary artery. In a follow-up examination, transthoracic echocardiography and computed tomography showed a left ventricular pseudo-false aneurysm, and therefore another operation was carried out. The operative findings showed that the heart markedly adhered to the pericardium and the aneurysm at the apex. The patient then underwent a double-patch closure of the ruptured point using an equine pericardial patch and a Dacron patch. No perioperative complication was observed. Left ventricular pseudo-false aneurysm is a rare complication following myocardial infarction. Here, we report a successful case of a double-patch closure of a pseudo-false aneurysm.
