Key result
Ablating AF within one year of diagnosis cuts recurrence by ~24% versus longer delays.
Why the study?
Does a shorter diagnosis-to-ablation time (< 1 year or < 3 years) reduce the recurrence of atrial fibrillation in patients awaiting ablation procedures?
Meta-Analysis (n=16,093)
Does a shorter diagnosis-to-ablation time (< 1 year or < 3 years) reduce the recurrence of atrial fibrillation in patients awaiting ablation procedures?
Shorter diagnosis-to-ablation time (<1 year or <3 years) is associated with a significantly lower risk of atrial fibrillation recurrence following catheter ablation.
Supports expedited ablation referral within 1 year of AF diagnosis; extends evidence on optimal timing to improve outcomes.
A diagnosis-to-ablation time of < 1 year and < 3 years is associated with a significantly lower risk of atrial fibrillation reccurence compared to a time of > 1 year and > 3 years in atrial fibrillation patients awaiting ablation procedures.

Najeeb et al. (2025) conducted a meta-analysis in Atrial Fibrillation (n=16,093). Diagnosis-to-Ablation Time (DAT) ≤ 1 year vs. Diagnosis-to-Ablation Time (DAT) > 1 year was evaluated on Atrial fibrillation recurrence (RR 0.76, 95% CI 0.66-0.86, p=<0.0001). A diagnosis-to-ablation time of 1 year or less significantly reduced the incidence of atrial fibrillation recurrence compared with a time greater than 1 year (RR 0.76).
