Key result
Patients aged ≥65 years undergoing catheter ablation for atrial fibrillation had similar clinical success and thromboembolic complication rates compared to those <65 years (P=0.67).
Why the study?
Does age < 65 years compared to ≥ 65 years affect long-term mortality, thromboembolic events, and success rates in patients undergoing catheter ablation for drug-refractory atrial fibrillation?

Does age < 65 years compared to ≥ 65 years affect long-term mortality, thromboembolic events, and success rates in patients undergoing catheter ablation for drug-refractory atrial fibrillation?
Catheter ablation for drug-refractory atrial fibrillation yields similar long-term clinical success and thromboembolic complication rates in patients aged ≥ 65 years compared to younger patients, supporting more liberal age criteria for the procedure.
AF ablation outcomes appear comparable by age in selected patients; leaves open whether age should guide CA selection in broader cohorts.
BACKGROUND: . ≥ 65 years who underwent catheter ablation (CA) for drug-refractory AF. METHODS: Consecutive patients with primary pulmonary vein isolation performed between March 2001 and December 2011, and those who completed a five-year of follow-up were divided into two groups: patients aged < 65 years into group 1, and patients aged ≥ 65 into group 2. Long-term outcome data concerning mortality, thromboembolic events (TE) and success rates were compared between these groups. CONCLUSIONS: Despite growing prevalence of AF in aging population, the elderly patients are underrepresented in CA procedures. Similar clinical success and TE complication rate are observed between the age-groups. Our data suggest more liberal criteria might be applied while selecting patients for AF ablation.

Kis et al. (2017) conducted a cohort in drug-refractory atrial fibrillation. Age ≥ 65 years vs. Age < 65 years was evaluated on mortality, thromboembolic events, and success rates (p=0.67). Patients aged ≥65 years undergoing catheter ablation for atrial fibrillation had similar clinical success and thromboembolic complication rates compared to those <65 years (P=0.67).
