Key result
Delayed initial AF ablation is linked to a ~5% higher 3-year risk of repeat ablation.
Why the study?
Real-world data regarding the clinical course of AF patients following initial catheter ablation remain limited and are primarily derived from specific registries or selected high-volume centers.
Observational (n=1,777)
Effect estimate: HR 1.05 (95% CI 1.01-1.08)
p-value: p=0.005
This paper discusses the current status and real-world clinical course of patients undergoing catheter ablation for atrial fibrillation in Japan.
May support earlier AF ablation to reduce repeat procedures; leaves open need for randomized confirmation.
Catheter ablation for atrial fibrillation (AF) has been an established and frequently utilized approach in a variety of clinical settings. Nevertheless, real-world data about the clinical course of AF patients after initial catheter ablation remain limited, and these are mainly derived from particular registries or selected high-volume centers.

Arita et al. (2021) conducted an observational in Atrial fibrillation (n=1,777). Catheter ablation was evaluated on Admission to hospital because of repeated catheter ablation within 3 years after the initial ablation (HR 1.05, 95% CI 1.01-1.08, p=0.005). A longer time from atrial fibrillation diagnosis to initial catheter ablation (7-11 months vs 1-6 months) was independently associated with an increased risk of repeated ablation (HR 1.05) within 3 years.
