D-PO04-201 - Safety Of Atrial Fibrillation Catheter Ablation In Octogenarians- Multicentre Experience (ID 1233)

Abstract

Background: Catheter ablation for atrial fibrillation (AF) is becoming increasingly common, however, there is limited data on procedural risk in octogenarians.
Objective: To review complication rates of patients aged >80 years old, undergoing catheter ablation for AF.
Methods: All patients who underwent catheter ablation for AF between 2013 and 2017 were retrospectively analysed from three tertiary cardiology centres. Complications were identified in the entire cohort, as well as in octogenarians.
Results: 3536 consecutive patients with a mean age= 63.0±11.0 (female =31.0%) had an AF ablation procedure over a 5-year period; 95% of the procedures were radiofrequency catheter ablation procedures and 5% utilised the cryoablation technique. Complications were identified in 2.91% (95% CI:2.36-3.47) of the entire cohort. Octogenarians comprised of 120 patients (3.73%), with a mean age of 82.6±1.2 (female = 57%). Complication rates in octogenarians were 4.17% (0.54-7.80) compared to 2.87% (2.31-3.43) in patients aged under 80 years old, with no significant difference between the two groups (p= 0.41). Complications in octogenarians consisted of groin haematoma (1.67%), pneumonia (1.67%) and pericardial effusion (0.83%). All complications occurred acutely. Female octogenarians were significantly more at risk of complications compared to male octogenarians; 7.35% of females suffered complications compared to 0% of males (p=0.048).
Conclusion: There is no significant difference between complication rates in octogenarians compared to patients who are younger, undergoing catheter ablation for AF. When complications do occur, female octogenarians are significantly more at risk than their male counterparts.
