text: Myocardial ischemia is a substrate for sustained polymorphic VT, or VF. Revascularization is a treatment of choice for myocardial ischemia. Survival after CABG in patients with life-threatening ventricular arrhythmia was reasonable. For patients with ischemic heart disease and reduced LVEF undergoing CABG, the risk of sudden cardiac death lessened compared with medical therapy. Among  survival of SCD, the risk of death reduced by revascularization procedure including PCI or CABG. Ischemic heart disease is responsible for 24% to 55% of SCD  cases in young patients <35 years of age. Anomalous aortic origin of the coronary arteries   detected in 10% to 17% of patients in postmortem  studies, is an important cause of SCD in the young. Revascularization is recommended for treating ischemia leading life-threatening ventricular arrhythmia due to anomalous aortic origin of the coronary arteries. Cardiac surgery is rarely performed for treating ventricular tachycardia in case of highly symptomatic patients with failed antiarrhythmic medications or unsuccessful ventricular ablation. Inaccessible sites for ventricular ablation including area deep in the myocardium, beneath epicardial fat, or near the coronary arteries  may lead to unsuccessful ablation. Surgical ablation  of ventricular arrhythmia can be done during other surgical intervention  such as placement of LVAD or at the time of left ventricular aneurysectomy which is a substrate for VT. VT or VF maybe provoked by Sympathetic activation and maybe inhibited by parasympathetic activity. Prevention of ventricular arrhythmia can be done by interruption of sympathetic outflow to the heart, pharmacological beta-blockade, or through stimulation of the parasympathetic pathway (vagal nerve stimulators, spinal cord stimulators). Autonomic modulation  is effective in conditions such as long QT syndrome and catecholaminergic polymorphic ventricular tachycardia. Efficacy for  ventricular tachycardia is under investigation. Atenolol was effective for controlling symptomatic  ventricular tachycardia in patients without structural heart disease.
