D-PO04-140 - Trends In Efficacy And Safety Of Catheter Ablation For Atrial Fibrillation In Octogenarians (ID 1209)


Background: The prevalence of AF keeps increasing especially in the elderly population. Because catheter ablation (CA) is an effective treatment for AF and new technologies such as contact force or ablation index have been innovated for improving efficacy and safety of CA, the need for CA is growing in octogenarian patients. However, efficacy and safety of CA for AF in octogenarians remain poorly studied.
Objective: The purpose of this study was to investigate trends in efficacy and safety of CA for AF among octogenarians in the last 5 years.
Methods: From 2014 to 2018, out of 2970 patients undergoing CA for AF, 80 procedures in 73 octogenarians who underwent their initial procedures were included in this study. We analyzed trends in proportion of octogenarian cases, incidence of peri-procedural complications, and 1-year outcomes after initial procedures.
Results: The proportion of octogenarian cases to the overall cases significantly increased from 0.6% to 4.3% year by year (p < 0.001). Overall complications occurred in 21.3% of 80 procedures including only 1 major complication: cardiac tamponade. Almost all of minor complications were rebleeding at the vascular access sites (n = 12). After the initial procedure, 1-year survival free from AF was 74% in 73 cases, but dramatically improved yearly up to 89.3% (p = 0.001). Clinical success (symptomatic or documented AF <1 hour/month with or without antiarrhythmic drugs) was also achieved increasingly year by year up to 92.9% (p = 0.014).
Conclusion: CA for AF in octogenarians is constantly increasing with improving efficacy and keeping safety. These findings support CA as a reasonable treatment option in octogenarians with symptomatic AF.
