OPTION
Comparison of Anticoagulation With Left Atrial Appendage Closure After Atrial Fibrillation Ablation
Patient / Population Intervention / Exposition Vergleich Endpunkt
In 1,600 patients with atrial fibrillation who underwent catheter ablation, left atrial appendage closure was non-inferior for death, stroke, or systemic embolism and reduced bleeding compared with oral anticoagulation.

1.600
Design
Multicentre open-label RCT (dual primary: efficacy non-inferiority, safety superiority)
Endpunkt
Efficacy: all-cause death, stroke, or systemic embolism; Safety: non-procedural major or CRNM bleeding

ErgebnisEfficacy 5.3% vs 5.8% at 36 months (non-inferior; P<0.001). Bleeding 8.5% vs 18.1% (superior for LAA closure; P<0.001).

Diskussion & Kritik
Open-label design and a bleeding endpoint driven partly by anticoagulation exposure temper interpretation. Supports LAA closure as an alternative to continued anticoagulation after AF ablation in patients at bleeding risk.
