Letter by Di Marco et al Regarding Article, “Electrical and Structural Substrate of Arrhythmogenic Right Ventricular Cardiomyopathy Determined Using Noninvasive Electrocardiographic Imaging and Late Gadolinium Magnetic Resonance Imaging”

We have read with great interest the article by Andrews et al.1 Noninvasive assessment of electrical abnormalities has a great potential to refine diagnosis and improve risk stratification in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC), as well as in other cardiomyopaties and channelopathies. Moreover, noninvasive characterization of the arrhythmic substrate is extremely helpful for ventricular tachycardia ablation, and there is now evidence that imaging-guided ventricular tachycardia ablation is associated with better outcome.2 Unfortunately, the present work did not include patients with history of ventricular tachycardia; however, the correlation between premature …
