Abstract
Ventricular tachycardia (VT) is a major cause of sudden cardiac death. The majority of malignant VTs which carry an elevated risk for sudden cardiac death (SCD), occur in patients with structural heart disease (SHD); currently implantable cardioverter defibrillators (ICDs) are the mainstay of therapy [1]. In these individuals, catheter ablation is being increasingly performed as adjunctive therapy to prevent or reduce ICD therapies when antiarrhythmic drugs are ineffective or contraindicated. In addition, in developing countries, some VT patients with structural heart disease cannot afford the expense of ICD; antiarrhythmic drugs and catheter ablation may become the ultimate therapy to prevent VTs and the onset of SCD.
