Additional left atrial appendage isolation during balloon ablation for persistent or long-standing persistent atrial fibrillation can reduce atrial fibrillation reoccurrence within 3-12 months compared to balloon-based pulmonary vein isolation only.
Persistent or long-standing persistent AF (i.e. continuous AF that was/is sustained >7 days or >12 months, respectively)
Age ≥18 and ≤80 years
Indication for AF ablation as per current guidelines
Missing informed consent
LAA diameter >25mm 10mm distant from circumflex artery assessed by TEE
Paroxysmal atrial fibrillation
Long-standing persistent atrial fibrillation with a continuous AF duration of >4 years
