16-13: Comparision of Outcomes of Atrial Fibrillation Ablation Procedures between an Octagenerian cohort of patients and an Young-Old cohort of patients

Background: Atrial Fibrillation (AF) ablations are performed in pts of all age groups. No data exists on the outcomes or Quality of Life (QOL) specific to the octogenarian population undergoing this procedure. We hypothesize the outcomes and risks would not be too dissimilar when compared to a younger cohort between 65-79 years. Methods: From a retrospective database we selected octogenarian pts compared to an age and sex matched control group, ages 65-79. Pre-ablation tests were performed as well as quality of life (QoL) and symptom inventories. Results of the ablation procedure, follow up QoL and symptom inventories, peri-procedure morbidity and freedom from AF or control of AF with anti-arrhythmic agents were compared between the 2 groups. Results: During follow-up (mean 2.3 ± 2.2 years), AF elimination (70% vs 81%, p 0.942) and AF control including those on antiarrhythmic agents (86% vs 86%, p 0.249) were compared. Conclusion: Outcomes of ablation in the octogenarians are highly favorable with no increase in procedural complications. Improvement in QOL scores is impressive in patients with advancing age.
