Surgery for left ventricular aneurysm. Early survival with and without endocardial resection.
In the past 3 years, 86 patients had left ventricular aneurysms resected or plicated. Sixty-eight had recurrent sustained ventricular tachycardia as the indication for surgery and had preoperative and intraoperative electrophysiologic mapping. There were 14 hospital deaths (16%). Eight preoperative potential risk factors for early hospital mortality were analyzed by multivariate analysis. Only acute myocardial infarction within 30 days before surgery correlated with hospital death at the p less than 0.05 level. History of previous heart surgery and advanced New York Heart Association functional class were important risk factors at the p less than 0.1 level. Hospital mortality was 17.6% for patients who had intraoperative mapping and endocardial resection and 11.1% for the others. Patients who had aneurysm repair for ventricular tachycardia had a significantly higher incidence of low cardiac output early after surgery (p less than 0.025).
