Key result
Stopping OAC after successful AF ablation may be considered to lower bleeding risk.
Why the study?
There is no clear consensus on the safety of oral anticoagulation discontinuation after atrial fibrillation ablation despite its increasing use and guideline recommendations to continue OAC based on stroke risk scores.
Does discontinuation of oral anticoagulation reduce bleeding without increasing stroke risk in patients who have undergone catheter ablation for atrial fibrillation?
Does discontinuation of oral anticoagulation reduce bleeding without increasing stroke risk in patients who have undergone catheter ablation for atrial fibrillation?
This review proposes a paradigm shift toward risk-stratified discontinuation of oral anticoagulation in patients without atrial fibrillation recurrence after catheter ablation.
May support individualized OAC decisions post-ablation; leaves open confirmatory RCTs before practice change.
AF is the most common arrhythmia in adult patients and frequently requires oral anticoagulation (OAC) for stroke prevention. Catheter ablation for AF has become an increasingly popular rhythm control strategy, although there is no clear consensus on the safety of OAC discontinuation after ablation. While current guidelines recommend continuing OAC after AF ablation based on CHA2DS2-VASc score, recent evidence suggests it may be safe and beneficial to discontinue OAC in appropriate populations. Catheter ablation has been shown to reduce both overall AF burden and stroke risk in large prospective studies. The ALONE-AF and OCEAN trials demonstrated that discontinuing OAC after AF ablation did not increase stroke incidence, but did reduce clinically significant bleeding events. A possible framework for discontinuing OAC could involve a risk-stratified approach to guide ambulatory monitoring for AF recurrence. In summary, OAC discontinuation may be considered in patients with no or minimal evidence of AF recurrence after catheter ablation.

Dowell et al. (2026) conducted a review in Atrial Fibrillation. Oral anticoagulation discontinuation vs. Oral anticoagulation continuation was evaluated. Discontinuing oral anticoagulation may be considered in patients with no or minimal evidence of atrial fibrillation recurrence after catheter ablation to reduce bleeding risk.
