Key result
History as an endurance athlete significantly predicted the need for a repeat ablation procedure due to VA recurrence in ARVC patients (HR 3.014; 95% CI 1.493-6.084; P=0.002).
Why the study?
The reason for recurrence of ventricular arrhythmia after catheter ablation in patients with arrhythmogenic right ventricular cardiomyopathy was not clear.
Does history as an endurance athlete predict ventricular arrhythmia recurrence after catheter ablation in patients with ARVC?
Population
91 ARVC patients undergoing catheter ablation for drug-refractory VA
Comparison
Single vs multiple ablation procedures
Design
Cohort study
Follow-up
Mean 32 ± 26 months

Endurance athlete history may identify ARVC patients needing closer post-ablation monitoring; leaves open whether activity restriction reduces recurrence.
Cohort (n=91)
Does history as an endurance athlete predict ventricular arrhythmia recurrence after catheter ablation in patients with ARVC?
Effect estimate: HR 3.014 (95% CI 1.493-6.084)
p-value: p=0.002
In patients with ARVC undergoing catheter ablation for ventricular arrhythmias, a history as an endurance athlete strongly predicts arrhythmia recurrence and the need for repeat ablation due to scar progression.
Lin et al. (2019) conducted a cohort in Arrhythmogenic right ventricular cardiomyopathy (ARVC) (n=91). Catheter ablation was evaluated on Need of a repeat procedure (HR 3.014, 95% CI 1.493-6.084, p=0.002). History as an endurance athlete significantly predicted the need for a repeat ablation procedure due to VA recurrence in ARVC patients (HR 3.014; 95% CI 1.493-6.084; P=0.002).
