Key Points
- Compare the diagnostic capability of electroanatomic voltage mapping and contrast-enhanced cardiac magnetic resonance in identifying ventricular scar lesions in patients with arrhythmogenic right ventricular cardiomyopathy.
- Evaluated right ventricular scar lesions using electroanatomic voltage mapping (EVM) and contrast-enhanced cardiac magnetic resonance (CE-CMR) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC).
- Assessed left ventricular delayed contrast enhancement (LV DCE) via CE-CMR to investigate biventricular disease involvement.
- Both EVM and CE-CMR detect right ventricular scar lesions in the majority of ARVC patients, though CE-CMR demonstrates lower sensitivity than EVM.
- High prevalence of LV delayed contrast enhancement on CE-CMR confirms frequent biventricular involvement and demonstrates the diagnostic relevance of assessing left ventricular scar.

While CE-CMR is less sensitive than EVM for detecting RV scars in ARVC, it is highly relevant for detecting frequent left ventricular involvement.
