Pilot Study of Catheter Ablation for Ventricular Tachycardia in Patients With an Implantable Cardioverter Defibrillator

Summary

The purpose of this pilot trial is to determine the feasibility of a large, multi-center randomized clinical trial aimed to test whether a treatment strategy of percutaneous catheter ablation of ventricular tachycardia (VT) is superior to state-of-the-art pharmacologic therapy at reducing all-cause mortality in patients with an implantable cardioverter defibrillator (ICD) who receive therapy for VT in the absence of any reversible cause.
