Key result
Endomyocardial biopsy guided by electroanatomic voltage mapping was diagnostic for ARVC/D in 75% of patients with overt disease and 87% of patients with suspected disease (P=NS).

Absolute Event Rate: 75% vs 87%
p-value: p=NS
Endomyocardial biopsy guided by electroanatomic voltage mapping provides a high diagnostic yield for confirming ARVC/D in patients presenting with low-voltage right ventricular areas.
Avella et al. (2008) conducted an observational in Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) (n=22). Endomyocardial biopsy guided by electroanatomic voltage mapping was evaluated on Diagnostic confirmation of ARVC/D (p=NS). Endomyocardial biopsy guided by electroanatomic voltage mapping was diagnostic for ARVC/D in 75% of patients with overt disease and 87% of patients with suspected disease (P=NS).
