Overview
Low-voltage burden may refine arrhythmic risk stratification in ARVC/D; leaves open prospective validation beyond current models.
Structured PICO
Does the extent of bipolar right ventricular endocardial low-voltage area predict arrhythmic outcomes in patients with ARVC/D?
P
Population
69 consecutive patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D), median age 35 years [28-45], 47 males.
I
Intervention
Endocardial voltage mapping (EVM) assessing the extent of bipolar (<1.5 mV) and unipolar (<6.0 mV) low-voltage electrograms
O
Outcome
Arrhythmic events (sudden death, appropriate implantable cardioverter defibrillator interventions, or sustained ventricular tachycardia) during a median follow-up of 41 monthshard clinical
The extent of bipolar right ventricular endocardial low-voltage area on electroanatomic mapping is a strong, independent predictor of arrhythmic events in patients with ARVC/D.
