“…9 Although there was one study reported a success rate of AF ablation in a low-volume center with 19.5% recurrence of paroxysmal AF in one year and 23.8% recurrence of persistent AF in one year, this study could not be compared directly to our cohort due to different AF ablation technique and method of obtaining data. 10 There are several interesting points in our study that are different from the studies from Western countries.…”

Background The result of atrial fibrillation (AF) ablation varies across centers. Most data are derived from the Western world, while data from Southeast Asian countries are lacking. We aimed to investigate the outcomes of AF ablation in Thailand. Method We performed a retrospective analysis of patients who underwent AF ablation in a tertiary care center, between the years 2006–2020. Details of AF ablation, including pulmonary vein isolation (PVI), and complex fractionated atrial electrogram (CFAE) ablation, were classified. The success rate of AF ablation is determined by freedom from AF beyond 3 months blanking period. Combined success rate of AF ablation was reported along with the success rate of each technique (PVI, CFAE, and combine PVI plus CFAE). Result We identified a total of 171 patients who underwent the first AF ablation. Ninety-four (55%) patients went through PVI, 55 (32%) patients for CFAE ablation, and 22 (13%) patients for PVI plus CFAE ablation. Overall freedom from AF was 73% at 12 months, 66% at 24 months, and 55% at 36 months. The success rate of PVI was 79% at 12 months, 74% at 24 months, and 59% at 36 months. The success rate of CFAE ablation was 63% at 12 months, 51% at 24 months, and 47% at 36 months. Conclusion Catheter ablation of AF is proven safe and effective in Thai population.
