Catheter Ablation for Scar-Dependent Ventricular Tachycardia

Chapter

Abstract

Ventricular tachycardia (VT) related to structural heart disease and scar is often recurrent and inadequately controlled with antiarrhythmic medication. Catheter ablation has been increasingly utilized to reduce ICD shocks and improve quality of life. With improved imaging and ablation techniques, multiple and unstable VTs can be successfully targeted with ablation resulting in significant reduction in VT recurrence. There is now substantial experience with ablation for scar VT such that it should be considered early in the course of recurrent VT. This chapter reviews the pathophysiology of scar VT, the various techniques currently utilized for mapping and ablation together with outcomes and complications relating to VT ablation.
