Key result
Longer delay to AF ablation linked to increased risk of arrhythmia recurrence.
Why the study?
Postprocedural recurrence remains a challenge after catheter ablation for AF, and few reports from primary care institutions in Japan have examined the effects of early ablation.
Does a shorter time from onset or diagnosis to catheter ablation improve sinus rhythm maintenance in patients with atrial fibrillation?
Observational (n=97)
Yes
Does a shorter time from onset or diagnosis to catheter ablation improve sinus rhythm maintenance in patients with atrial fibrillation?
p-value: p=<0.001
Early referral for catheter ablation after atrial fibrillation onset or diagnosis improves sinus rhythm maintenance rates.
May support earlier AF ablation referral; hypothesis-generating, should not yet change practice.

Matsumoto et al. (2020) conducted an observational in Atrial Fibrillation (n=97). Catheter ablation vs. Longer time from onset or diagnosis to ablation was evaluated on Recurrence of atrial arrhythmia lasting ≥30 seconds after 3 months post-ablation (p=<0.001). A longer duration from the onset or diagnosis of atrial fibrillation to catheter ablation significantly increased the risk of arrhythmia recurrence after the initial procedure (p<0.001).
