dc.description.abstract | BACKGROUND Empiric circumferential pulmonary vein isolation (CPVI) has become the therapy of choice for drugrefractory atrial fibrillation (AF). Although results are suboptimal, it is unknown whether mechanistically-based strategies targeting AF drivers are superior. OBJECTIVES This study sought to determine the efficacy and safety of localized high-frequency source ablation (HFSA) compared with CPVI in patients with drug-refractory AF. METHODS This prospective, multicenter, single-blinded study of 232 patients (age 53 10 years, 186 males) randomized those with paroxysmal AF (n ¼ 115) to CPVI or HFSA-only (noninferiority design) and those with persistent AF (n ¼ 117) to CPVI or a combined ablation approach (CPVI þ HFSA, superiority design). The primary endpoint was freedom from AF at 6 months post-first ablation procedure. Secondary endpoints included freedom from atrial tachyarrhythmias (AT) at 6 and 12 months, periprocedural complications, overall adverse events, and quality of life. RESULTS In paroxysmal AF, HFSA failed to achieve noninferiority at 6 months after a single procedure but, after redo procedures, was noninferior to CPVI at 12 months for freedom from AF and AF/AT. Serious adverse events were significantly reduced in the HFSA group versus CPVI patients (p ¼ 0.02). In persistent AF, there were no significant differences between treatment groups for primary and secondary endpoints, but CPVI þ HFSA trended toward more serious adverse events. CONCLUSIONS In paroxysmal AF, HFSA failed to achieve noninferiority at 6 months but was noninferior to CPVI at 1 year in achieving freedom of AF/AT and a lower incidence of severe adverse events. In persistent AF, CPVI þ HFSA offered no incremental value. (Radiofrequency Ablation of Drivers of Atrial Fibrillation [RADAR-AF]; NCT00674401) (J Am Coll Cardiol 2014;64:2455–67). | es_ES |
