Surgical treatment in postinfarction left ventricular pseudoaneurysm

AIM: We evauated the outcome of patients with left ventricular pseudoaneurysms, focusing on those treated surgically. METHODS: Between June 1990 and March 2007, 7 patients underwent surgery because of left ventricular pseudoaneursym following myocardial infarction, at our institution. The median time interval between myocardial infarction and the diagnosis of left ventricular psedoaneursym was 2.6 months (range: 15 days to 8 months). The aneursym was resected and the defect was closed with a Teflon patch or direct sutures. RESULTS: The location of the pseudoaneursym was posterior in 3 patients, inferolateral in 3 patients and anterolateral in 1 patient. The aneursym was resected and the defect was closed with a Teflon patch in 6 patients. In 1 patient with chronic pseudoaneurysm, the defect was closed with direct sutures reinforced with Teflon felt. In addition, 5 patients underwent coronary artery bypass grafting. The patients have been followed-up for a mean period of 45 months (range: 24 to 109 months). CONCLUSION: There was no intraoperative death. However, 2 patients died due to multiple organ failure, one 17 days and the other 1 month after the surgical operation. There was 1 late death due to the cancer. Currently, 1 patient is free of any cardiac symptoms, 2 patients have New York Heart Association (NYHA) Class II heart failure, and 1 patient with moderate mitral regurgitation is in class III.
