Diagnostic Value of Endomyocardial Biopsy Guided by Electroanatomic Voltage Mapping in Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia

Abstract

The results of our study (1) confirm the high diagnostic sensitivity of RV voltage mapping in patients with overt ARVC/D, (2) document a high prevalence of RV low-voltage areas even in patients with suspected ARVC/D, and (3) demonstrate that in patients with clinical evidence or suspicion for ARVC/D, presenting RV low-voltage areas, EMB guided by voltage mapping may provide ARVC/D diagnosis confirmation.
