Efficacy, safety and outcome of catheter ablation for atrial fibrillation in octogenarians

Abstract

Background and objectives: Catheter ablation is effective in treating patients with atrial fibrillation (AF). The aim of the study was to evaluate the safety, efficacy and outcome of catheter ablation for AF in octogenarians.

Methods and results: 377 consecutive patients were divided into three groups based on age: ≥80 years (group 1; n=49), 70-79 years (group 2; n=151), 60-69 years (group 3; n=177). The efficacy and safety for those three groups were determined. The success rate after one procedure was similar in three groups (70% in group 1, 72% in group2 and 74% in group 3, P=NS) during a mean follow-up of 18 months. Major complication rates were comparable between the three groups. However, the octogenarians were less likely to undergo a repeated procedure than other groups (8% in group 1, 15% in group 2 and 18% in group 3, P<0.05), and were more likely to remain on antiarrhythmic drugs.

Conclusion: Catheter ablation for AF attempted in octogenarians appears to be effective and with low risk. Ablation results are comparable with those noted in younger patients.
