Epicardial Approach in Recurred Atrial Fibrillation
South Korea100 participantsStarted 2016-06-29
Plain-language summary
We aimed to assess the benefit of epicardial mapping and ablation in patients with recurred atrial tachyarrhythmias after single procedure for atrial fibrillation. We hypothesize that both endocardial and epicardial approach is superior to only endocardial approach with regards to clinical recurrence. Participants are randomized into a hybrid approach or an endocardial approach.
