Key result
Late potential abolition during ventricular tachycardia ablation strongly predicted VT-free survival in ARVC patients (HR 0.075; 95% CI 0.008-0.661; P=0.020).

May guide ablation endpoints in ARVC; leaves open confirmation via randomized trials regardless of RV disease.

Does VT ablation targeting late potential abolition prevent VT recurrence in ARVC patients with and without structural RV disease?
Absolute Event Rate: 15% vs 40%
p-value: p=0.17
In patients with ARVC, VT ablation targeting late potential abolition is effective in preventing VT recurrence, regardless of the presence of structural RV disease.
Kirubakaran et al. (2017) conducted a cohort in Arrhythmogenic right ventricular cardiomyopathy (n=29). Ventricular tachycardia ablation vs. Structural vs electrical RV cardiomyopathy was evaluated on Ventricular tachycardia recurrence (p=0.17). Late potential abolition during ventricular tachycardia ablation strongly predicted VT-free survival in ARVC patients (HR 0.075; 95% CI 0.008-0.661; P=0.020).
