Overview
Surgery is not a mainstay or a preferred method of treatment for ventricular tachycardia. There are some specific scenarios however in which revascularization may be considered, and may help in preventing VT.
Surgery and Revascularization Procedures in Patients With Ischemic Heart Disease
- Myocardial ischemia is a substrate for sustained polymorphic VT, VF
- Revascularization is a treatment of choice for myocardial ischemia.
- Survival after CABG for life-threatening ventricular arrhythmia was better.
- For patients with ischemic heart disease and reduced LVEF undergoing CABG the risk of sudden cardiac death lessened compared with medical therapy.
- In survival of SCD the risk of death reduced by revascularization procedure including PCI or CABG.
Surgery
According to a few studies and opinions, patients with ventricular tachycardia may be considered for surgery (revascularization) if the underlying cause is coronary heart disease and the patient:[1][2][3][4][5]
- Does not respond to antiarrhythmic drug therapy.
- Has had a cardiac arrest in the past, and had monomorphic VT. This is especially desirable in patients who are already being considered for surgical revascularization.
- Has ventricular tachycardia and a disorder that is pathophysiologically related to the VT (such as postoperative tetralogy of Fallot).
- Despite these ideas, revascularization alone has not been shown to prevent VT from recurring.
