title: Treatment of early postinfarction ventricular aneurysm by intra-aortic balloon pumping and surgery.
abstract: In nine patients with medically refractory left ventricular failure and/or ventricular arrhythmias, secondary to acute formation of a ventricular aneurysm, intra-aortic balloon pumping (IABP) was instituted 24 to 36 hours before diagnostic angiographic studies. Ventricular irritability was reduced and heart failure was controlled in all patients. Eight patients underwent operation, four within 3 weeks of an acute myocardial infarction and four within 3 months. All had resection of the recent infarction and two had myocardial revascularization as well. Two of the eight patients died in the early postoperative period from intractable ventricular fibrillation. All six patients who survived the operation (mean follow-up 12 months) had excellent clinical results. Ventricular irritability was suppressed and only one patient had residual heart failure. However, there was one late death 7 months after operation. The results suggest that surgical therapy may be effective in the management of medically unresponsive arrhythmias and/or congestive heart failure in the acute or intermediate postinfarction phase. IABP assistance was helpful in supporting the circulation and reducing ventricular irritability during the preoperative and postoperative periods.
