Surgical treatment of aneurysm and segmental dyskinesia of the left ventricular wall after mycardial infarction
1973
Abstract From 1967 to 1971, 20 patients with left ventricular aneurysm or segmental dyskinesia were treated surgically. There was 1 hospital death; 2 other patients died 3 and 5 months, respectively, after operation. Cardiac failure (9 cases) and ventricular arrhythmias (9 cases) were the main indications for operation. Selective coronary arteriography was performed in 16 patients, and in all cases demonstrated significant obstruction. In 9 of these patients, aortocoronary bypass grafts were performed in addition to myocardial resection. The duration of follow-up studies ranged from 6 months to 4 years. Resection of the aneurysm gave good results irrespective of the indication for surgery. Results were less dramatic in repair of segmental dyskinesia. In the 9 latter cases, better results were obtained when the indication for surgery was arrhythmia.
