Abstract

A 56-year-old man with nonischemic cardiomyopathy underwent orthotopic cardiac transplantation after endocardial and epicardial radiofrequency catheter ablation for pleomorphic ventricular tachycardia. The myocardial substrate and epicardial fat were comprehensively analyzed with three-dimensional electroanatomic maps, late gadolinium enhanced ex-vivo cardiac magnetic resonance, and histological examination. The association of scar, viable myocardium, and epicardial fat with endocardial and epicardial electrogram voltage and duration was quantitatively defined. This case provides a unique opportunity to explore the reliability of electrical surrogates of scar in nonischemic cardiomyopathy. (PACE 2012;35:e345-e348)
