Ostial vs. wide area circumferential ablation guided by the Ablation Index in p...
Sousa, Pedro A.; Barra, Sérgio; Saleiro, Carolina; Khoueiry, Ziad; Adão, Luís; Primo, João; Lagrange, Philippe; Lebreiro, Ana; Fonseca, PauloPulmonary vein isolation (PVI) guided by the Ablation Index (AI) has shown high acute and mid-term efficacy in the treatment of paroxysmal atrial fibrillation (AF). Previous data before the AI-era had suggested that wide-area circumferential ablation (WACA) was preferable to ostial ablation. However, with the use of AI, we hypothesize that ostial circumferential ablation is non-inferior to WACA and can improve ...
Two years after pulmonary vein isolation guided by ablation index—a multicenter...
Sousa, Pedro A.; Puga, Luís; Adão, Luís; Primo, João; Khoueiry, Ziad; Lebreiro, Ana; Fonseca, Paulo; Lagrange, Philippe; Elvas, Luís; Gonçalves, LinoBackground: The use of the Ablation Index (AI) software for paroxysmal atrial fibril-lation (AF) has been associated with higher acute effectiveness and higher 1-year ar -rhythmia freedom. There is, however, a lack of data concerning longer follow-up. We aim to evaluate the 2-year outcomes after a standardized AI- guided pulmonary vein isolation (PVI).Methods: Prospective, multicenter study of consecutive patie...
