Cardiac Magnetic Resonance to Evaluate Complete Substrate Elimination after Endocardial Ventricular Tachycardia Ablation in Chagas Disease

Mauricio I. Scanavacca et al. Rodrigo M. Kulchetscki Carlos E. Rochitte Cristiano F. Pisani

Introduction

The main endpoint of ventricular tachycardia (VT) ablation includes elimination of the abnormal substrate on remapping and rendering non-inducible VT with programmed ventricular stimulation. ^,

Cardiac magnetic resonance (CMR) has been increasingly used as a tool for locating the arrhythmogenic substrate of patients with scar-related VT. The images can be integrated with the electroanatomical mapping to guide ablation to the identified channels responsible for the VT-reentry circuits, optimizing the ablation results. However, until now, CMR has not been used to confirm the complete substrate elimination and effectiveness of VT ablation.
