Left ventricular pseudo-false aneurysm perforating the right ventricle: two case reports

Abstract

Abstract Background Left ventricular (LV) pseudo-false aneurysm is a rare and fatal complication secondary to myocardial infarction. Sometimes, it may perforate the right ventricle (RV) and lead to acute heart failure. We experienced 2 cases of surgical repair of an LV pseudo-false aneurysm perforating the RV. Case presentation Case 1: A 76-year-old man was referred to our hospital due to dyspnea. Echocardiography revealed an LV pseudo-false aneurysm (25 mm × 20 mm) that had perforated the RV. Via LV incision, the two small orifices communicating to the RV were detected and closed by direct suture. A double patch of bovine pericardium and a dacron sheet was sutured around the aneurysm with everting mattress. Case 2: A 51-year-old man, who had undergone percutaneous coronary intervention 1 month before, was referred to our hospital due to an LV aneurysm perforating the RV. Via LV incision, a double-layered patch was sutured around the aneurysm with everting mattress. The communicating hole to RV was closed by bovine pericardium patch with a running suture via an RV incision. Postoperative course was uneventful in both cases. Conclusions An LV pseudo-false aneurysm perforating the RV should be considered for urgent repair before serious complications arise and the patient’s general condition deteriorates.
