A 60-year-old man with persistent AF for 2 years undergoes successful catheter ablation (pulmonary vein isolation). He has been in sinus rhythm for 3 months post-ablation and asks whether he can stop apixaban (CHA₂DS₂-VA score 3). What is the recommendation?

Correct answer: C — Continue anticoagulation indefinitely — OAC decisions should be based on stroke risk (CHA₂DS₂-VA), not on the apparent success of ablation or maintenance of sinus rhythm

The 2024 ESC AF Guidelines make a critical point: anticoagulation decisions should be based on the patient's stroke risk (CHA₂DS₂-VA score), NOT on the perceived success of rhythm control (including ablation). AF may recur asymptomatically after ablation, and stroke risk persists even in apparent sinus rhythm (possibly due to the underlying atrial substrate/myopathy). All patients with CHA₂DS₂-VA ≥2 should continue OAC indefinitely after ablation (Class I recommendation). This applies regardless of the type of rhythm control strategy (ablation or drugs). Stopping OAC after successful ablation remains an area of active research but is not currently recommended.
