Overview
Additional left atrial appendage isolation during balloon ablation for persistent or long-standing persistent atrial brillation can reduce atrial brillation reoccurrence within 3-12 months compared to balloon-based pulmonary vein isolation only.
Eligibility
Inclusion Criteria:
- 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
- Indication for LAA closure as per current guidelines
Exclusion Criteria:
- Missing informed consent
- LAA diameter >25mm 10mm distant from circumflex artery assessed by TEE
- Paroxysmal atrial brillation
- Long-standing persistent atrial brillation with a continuous AF duration of >4 years
- Previous pulmonary vein isolation or MAZE surgery
- Previous led atrial appendage closure or surgical excision
- Left atrial diameter >60 mm at baseline
- Left atrial thrombus at baseline
