Brief Summary:
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, associated with an increased risk of morbidity and mortality1. The management of AF patients is aimed at reducing symptoms and at preventing severe complications associated with AF. In the last years, two new strategies have emerged with different objectives. In the PROTECT AF study2, percutaneous closure of the Left Atrial Appendage (LAA) with a closure device provided an alternative strategy to oral anticoagulation for stroke prophylaxis. The AFFIRM trial3 has shown that drug-based management of AF with a rhythm-control strategy conferred no advantage over a rate-control strategy in cardiovascular mortality and might be associated with an increased noncardiovascular death rate4. Catheter ablation has gained a greater place in the rhythm control strategy, showing superiority in maintaining sinus rhythm in comparison with AAD5. However, in persistent AF, repeat ablation procedures are necessary in up to 70% of patients to achieve sinus rhythm at a long-term follow-up6-7.
This prospective, randomized trial will compare the percutaneous closure of the LAA combined with a rate-control strategy to catheter ablation in the management of patients with persistent AF. Patients who are eligible for catheter ablation as well as LAA closure device implantation and are willing to participate in the study will be randomly assigned to catheter ablation or percutaneous closure of the LAA by a closure device implantation in the relation 1:1. The primary endpoint of the study is a composite endpoint at 12 months of all cause death, thrombo-embolic events, major bleeding (BARC type 3), re-hospitalisation and severe symptoms due to arrhythmias. Secondary endpoints include a composite endpoint of bleeding, a composite endpoint of thrombo-embolic events, cardio-vascular mortality, total duration of hospitalisation, sustained discontinued anticoagulation, quality of life improvement, use of Antiarrhythmic Drugs (AAD), total costs, freedom from arrhythmia and average ventricular frequency in 7-day holter ECG at 12 months.
The objective of the study is to assess the superiority of percutaneous closure of the LAA combined with rate-control to catheter ablation in patients with oligosymptomatic AF.
