25 Jul 2025 • A study of 619 atrial fibrillation (AF) patients (mean age 63; 72% male; 34% non-paroxysmal) found that delaying catheter ablation (CA) ≥1 year post-diagnosis markedly raises recurrence risk.

Over a 3-year follow-up, 165 recurrences occurred, with a 2.3-fold higher risk in those with longer diagnosis-to-ablation times (DAT).

Risks were 2-fold higher in paroxysmal and up to 4-fold higher in non-paroxysmal AF for the longest DAT tertile (median 4 years), underscoring the benefit of early ablation to curb long-term recurrence.
