Does electroanatomical voltage mapping improve the diagnostic yield of endomyocardial biopsy in patients with suspected arrhythmogenic right ventricular cardiomyopathy?
Electroanatomical voltage mapping may guide endomyocardial biopsy to target affected right ventricular regions, potentially improving the diagnostic yield for ARVC.

May support targeted RV biopsy in suspected ARVC; leaves open whether yield improves in prospective series.
A positive endomyocardial biopsy (EMB) is a major diagnostic criterion for arrhythmogenic right ventricular cardiomyopathy (ARVC). Nevertheless, its sensitivity is low due to the focal nature of the disease. Moreover, myocardial samples are usually taken from the uncommonly involved interventricular septum to minimize the risk of perforation. In this report, we describe a novel bioptical approach for ARVC diagnosis guided by the identification of right ventricle (RV) affected regions by means of electroanatomical voltage mapping.

Avella et al. (2007) conducted a case report in Arrhythmogenic right ventricular cardiomyopathy (ARVC). Endomyocardial biopsy guided by electroanatomic voltage mapping was evaluated. Endomyocardial biopsy guided by electroanatomic voltage mapping is described as a novel approach to identify affected right ventricle regions for diagnosing ARVC.
