Serious ventricular arrhythmias, a common complication of coronary artery disease, frequently respond to medical management. When pharmacologic and pacemaker therapy fail to control them, however, surgical therapy must be considered. In this review we assess the efficacy of surgical treatment of these arrhythmias. Coronary revascularization fails to reduce the frequency and complexity of ventricular ectopic activity and may exacerbate them. Recurrent ventricular fibrillation due to acute, reversible ischemic events may respond favorably to coronary revascularization. Recurrent ventricular fibrillation associated with recent myocardial infarction when unresponsive to medical therapy can be managed with coronary revascularization and infarctectomy with comparatively good results. Recurrent sustained ventricular tachycardia is not optimally treated with coronary artery bypass grafting and myocardial resection. Operations guided by activation mapping that isolate or destroy the site of origin of the ventricular tachycardia show promise.
