Key result
Catheter ablation for premature ventricular contractions in ARVC patients achieved complete long-term success in only 12.5% of patients over a median follow-up of 345 days.
Why the study?
PVCs can occur at any stage of ARVC and are linked to sustained VT risk, but the role of PVC ablation in ARVC patients needed investigation.
Does catheter ablation reduce PVC burden in patients with arrhythmogenic right ventricular cardiomyopathy and symptomatic frequent PVCs?

Limited long-term PVC control after ablation in ARVC warrants caution; leaves open its role versus AADs in prospective studies.

Does catheter ablation reduce PVC burden in patients with arrhythmogenic right ventricular cardiomyopathy and symptomatic frequent PVCs?
Catheter ablation for PVCs in ARVC patients is not associated with consistent long-term reduction in PVC burden and often requires continued antiarrhythmic drug therapy.
Assis et al. (2021) conducted an observational in Arrhythmogenic right ventricular cardiomyopathy (ARVC) (n=8). Catheter ablation for premature ventricular contractions was evaluated on Complete long-term success (>80% reduction in PVC burden off of membrane-active AADs). Catheter ablation for premature ventricular contractions in ARVC patients achieved complete long-term success in only 12.5% of patients over a median follow-up of 345 days.
