Abstract
Twenty-one patients with coronary artery disease and severe, symptomatic ventricular arrhythmias underwent cardiac surgery after failure of medical managememt. All had coronary artery disease and either localized areas of severe hypokinesis (three patients), or ventricular aneurysms (18 patients) documented angiographically prior to surgery. Operation within one month after acute infarction resulted in an 80% in-hospital mortality, whereas operation more than one month postinfarction showed a 20% mortality. Operative treatment that included myocardial resection had a significantly lower mortality (P less than 0.05) than that which did not. With an average of 36.5 months of follow-up, 13 of the 21 patients were long-term survivors, despite the persistence of ventricular arrhythmias. Surgical treatment which includes myocardial resection and occurs more than one month after infarction should be considered in patients with symptomatic ventricular arrhythmias and severe, well-localized left ventricular wall motion abnormalities.
