Ventricular tachyarrhythmias are well-known complications of ischemic heart disease. Recurrent sustained ventricular tachycardia (VT) can now be easily recognized and is frequently reversed both in and out of hospital. Coronary artery bypass surgery with or without aneurysmectomy has been disappointing as therapy for these arrhythmias. With the advent of programmed electrical stimulation, it has become possible to distinguish automatic and reentrant ventricular tachyarrhythmias. The latter have recently proved amenable to operative intervention. In this review, the pathophysiology of VT as determined by programmed electrical stimulation is discussed. Surgical therapy with isolation, resection, revascularization, thermal ablation, cardiac pacing, reentrant circuit interruption, and endocardial excision is examined. Operation for cardiac arrhythmias is on a firm electrophysiologic foundation. Surgical treatment of refractory ventricular tachyarrhythmias is now reasonable, recommended, and rewarding.
