Surgical management of left ventricular aneurysm and diffuse coronary artery disease: immediate and long term results in patients receiving three or more grafts.
Because little information is available concerning the outcome of surgery for left ventricular aneurysm when multiple concurrent coronary grafts are required, we have reviewed 35 consecutive patients undergoing aneurysm surgery and multiple (greater than or equal to 3) grafts between December 1973 and April 1984. There were 6 operative deaths (17%). All occurred amongst those (16) undergoing LV plication procedures with no deaths amongst those (19) undergoing aneurysm resection (p less than 0.01). Operative mortality was not influenced by preoperative functional status, left ventricular end diastolic pressure, completeness of revascularisation, endarterectomy (13 patients) or whether cold crystalloid cardioplegia or intermittent aortic cross clamp with ventricular fibrillation was used. Overall 5-year actuarial survival was 70% with survival beyond surgery being 84% to 5 years and independent of the type of aneurysm procedure. Of the survivors, 16 were improved by 1-3 functional classes, 3 were unchanged and one was worse. Surgery in this group of patients offers the prospect of good symptomatic improvement and survival figures which at least equal the results of less complex ventricular aneurysm surgery and exceed those reported for medical management.
