Surgery
According to few studies, patients with ventricular tachycardia may be preferred for surgery if the underlying cause is coronary heart disease and the patient:
- Does not respond to antiarrhythmic drug therapy
- Has had a cardiac arrest in the past, and had monomorphic VT induced. 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.
• Patients with VT resistant to antiarrhythmic drug therapy
• Patients with a history of cardiac arrest in whom monomorphic VT is induced, especially if surgical revascularization is being considered
• Patients with VT in whom aneurysm resection and/or mitral valve surgery is being considered to control ventricular dysfunction
• Patients with VT and disorders associated with an identifiable pathophysiological substrate, such as postoperative tetralogy of Fallot
The ability to induce sustained monomorphic VT implies the presence of a fixed substrate; revascularization alone has not been shown to alter this substrate or prevent recurrent VT [13-15].
