N2 - Voltage Mapping-Guided Biopsy in ARVC/D. Introduction: To improve the endomyocardial biopsy (EMB) diagnostic sensitivity for arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D), we hypothesized a biopsy sampling focused on selected right ventricle (RV) low-voltage areas identified by electroanatomic voltage mapping. Methods and Results: The study population (22 patients, 10 men; mean age 34 ± 10 years) included 11 patients with overt ARVC/D (group A) and 11 patients with suspected ARVC/D (group B), according to both arrhythmic profile and standardized noninvasive diagnostic criteria. In all 22 patients, an RV bipolar voltage mapping was performed with CARTO™ system sampling multiple endocardial sites (262 ± 61), during sinus rhythm, with a 0.5-1.5 mV color range setting of voltage display. All 11 (100%) group A patients and 8 of the 11 (73%) group B patients (P = nonsignificant [NS]) presented RV low-voltage areas (
