Noninvasive Diagnosis of Electroanatomic Abnormalities in Arrhythmogenic Right Ventricular Cardiomyopathy
Why the study?
Do noninvasive diagnostic criteria (ECG, SAECG, CMR) correlate with electroanatomic abnormalities in patients with ARVC?
Population
17 patients aged 50 ± 16 years with biopsy specimen-proven arrhythmogenic right ventricular cardiomyopathy.
Design
Cross-sectional

Implication
CMR and ECG markers may aid noninvasive ARVC assessment; supports correlation with substrate but leaves open prospective validation.
Structured PICO
Do noninvasive diagnostic criteria (ECG, SAECG, CMR) correlate with electroanatomic abnormalities in patients with ARVC?
P
Population
17 patients (9 men) aged 50 ± 16 years with biopsy specimen-proven arrhythmogenic right ventricular cardiomyopathy (ARVC).
I
Intervention
Noninvasive diagnostic criteria including surface ECG, signal-averaged ECG (SAECG), and cardiac magnetic resonance (CMR)
O
Outcome
Association between noninvasive diagnostic criteria and the presence and location of low-voltage areas (LVAs) detected at right ventricular electroanatomic voltage mapping (EAM)surrogate
CMR delayed enhancement and surface ECG abnormalities strongly correlate with electroanatomic low-voltage areas in ARVC, supporting their diagnostic utility.
