Abstract

We report the case of a 52-year-old man who presented with a 2-week history of exertional dyspnea and was admitted to our hospital with heart failure. Coronary angiography showed severe three-vessel disease ; left ventriculography revealed an aneurysm in the inferior left ventricular (LV) wall perforating into the right ventricle. We suspected the LV aneurysm was from a previous myocardial infarction (MI) that had perforated into the right ventricle, although the time of MI was unclear. The patient was treated with medications initially. We subsequently treated the patient by LV aneurysm closure using a patch and direct closure of the perforation by incising the aneurysm. Coronary artery bypass grafting was performed in the left anterior descending artery, the diagonal artery, and the right coronary artery simultaneously. After having an uneventful postoperative course, he was discharged from the hospital in a stable condition. A pathology examination confirmed a diagnosis of LV pseudo-false aneurysm.
