The DESTINATION Study investigates whether anticoagulation therapy is necessary after successful catheter ablation (CA) for atrial fibrillation (AF). Current guidelines recommend continued anticoagulation based on stroke risk scores, even post-ablation, potentially exposing patients to unnecessary bleeding risks. This international, multicenter, randomized controlled trial aims to compare thromboembolic and bleeding event risks between patients who continue and discontinue anticoagulation after ablation. The study involves 3,160 AF patients, all free of AF recurrence within 6 months to 1 year after ablation. Smart wearable monitors will track recurrence, and patients are followed for 24 months to assess event rates. Findings may reshape anticoagulation guidelines, improving clinical practice for AF patients worldwide.
Age ≥18 years
Diagnosed paroxysmal, persistent, or longstanding persistent AF
Successful procedure (defined as restoration of sinus rhythm after PV isolation for paroxysmal AF, restoration of sinus rhythm after PV isolation and completion of additional ablation for persistent AF, according to 2017 HRS/EHRA/ECAS/APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation) and no recurrence within 3 months of ablation, using a cooled tip RF-, laser- or cryo-balloon-catheter
No periprocedural complications
Valvular AF (moderate- severe mitral insufficiency; relevant mitral stenosis with a mean pressure gradient >5mmHg)
Reversible AF (e.g. uncontrolled hyperthyroidism)
Prior AF ablation (including surgical ablation)
History of left atrial appendage occlusion/ligation/excision
