Abstract

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.

心房颤动的射频消融术：泰国三级医疗中心14年的经验。

背景：心房颤动（AF）消融的结果因中心而异。大多数数据来自西方世界，而缺乏来自东南亚国家的数据。我们旨在调查泰国房颤消融术的结果。方法：我们对2006-2020年间在三级医疗中心接受房颤消蚀的患者进行了回顾性分析。对AF消融的细节进行分类，包括肺静脉隔离（PVI）和复杂分割心房电图（CFAE）消融。房颤消融术的成功率取决于超过3个月的无房颤消隐期。报告了房颤消融的综合成功率以及每种技术（PVI、CFAE和PVI加CFAE）的成功率。结果：我们共确定了171名首次接受房颤消融术的患者。94名（55%）患者接受了PVI，55名（32%）患者接受CFAE消融，22名（13%）患者接受PVI加CFAE消融。12个月时房颤的总体缓解率为73%，24个月时为66%，36个月时则为55%。PVI在12个月时的成功率为79%，在24个月时为74%，在36个月时则为59%。12个月时CFAE消融成功率为63%，24个月时为51%，36个月时成功率为47%。结论：导管消融治疗房颤在泰国人群中是安全有效的。

期刊介绍： The Asian Cardiovascular and Thoracic Annals is an international peer-reviewed journal pertaining to cardiovascular and thoracic medicine. Besides original clinical manuscripts, we welcome research reports, product reviews, reports of new techniques, and findings of special significance to Asia and the Pacific Rim. Case studies that have significant novel original observations, are instructive, include adequate methodological details and provide conclusions. Workshop proceedings, meetings and book reviews, letters to the editor, and meeting announcements are encouraged along with relevant articles from authors.
