Objective:

To analyze the independent association between diagnosis-to-ablation time (DAT) and recurrent atrial fibrillation (AF) following catheter ablation (CA) in a clinical practice population.

Approach:
  • Study Design: Prospective, multicenter registry (REAL-AF) enrolling participants undergoing radiofrequency or pulsed field ablation for symptomatic AF.
  • Participants: Adult patients with symptomatic AF; long-standing and persistent AF were excluded.
  • Data Collection: DAT defined as the earliest year of AF documentation; follow-up included ECGs and continuous rhythm monitoring.
  • Outcomes: Primary outcome was freedom from all atrial arrhythmia at 1-year follow-up; secondary outcomes included procedural characteristics and long-term clinical outcomes.
  • Statistical Analysis: Kaplan-Meier survival analysis and Cox proportional hazards models assessed the association between DAT and arrhythmia-free survival.
Key Findings:
  • AF recurrence occurs in 20% to 40% of cases within 1 year after CA.
  • DAT is an important predictor of procedural efficacy.
  • The study analyzed 8189 index ablations, with various exclusions for missing data.
Interpretation:

Limitations:
  • Exclusion of long-standing and persistent AF may limit generalizability.
  • Missing data on DAT and follow-up may affect results.
Conclusion:
