Brief Summary:
Antecedents: electrical isolation of pulmonary veins is the standard treatment for patients with atrial fibrillation. However, its efficacy is lower in persistent and chronic forms of this arrhythmia compared to paroxysmal atrial fibrillation. Many complementary techniques have been proposed, that added to pulmonary veins isolation, may reduce the recurrence rate of atrial fibrillation. However, none of them has obtained consistent results. Linear ablation aims to parcellate and modify the left atrial substrate responsible for atrial fibrillation maintenance. Previous studies have offered contradictory results using linear ablation.
Methods: SUPAFER is a multicenter, 1:1 randomized clinical trial that compares the efficacy of pulmonary veins isolation alone vs pulmonary vein isolation plus an specific protocol of left atrial linear ablation. Contrary to previous studies, the specific SUPAFER linear ablation is systematic, homogeneous and target atrial areas that have not been systematically ablated in previous trials. The trial aims at demonstrating the superiority of the combined ablative approach during 1-year follow-up. Daily transtelephonic ECG samples a 30 days continuous ECG monitoring are used to maximize de detection of recurrences, even asymptomatic.
