  • Background Atrial fibrillation (AF) is the most frequent arrhythmia, and its prevalence is increasing with aging. We aimed to compare the long-term outcome data of patients vs. ? 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 Results A total number of 390 patients were included, group 1 contained 310 patients, and 80 patients in group 2. In group 2, patients had more often impaired renal function (P P = 0.047). A total of fifteen patients died during the 6.63 ± 2.1 years of follow-up, with a significantly higher incidence in the older group (8/80 vs. 7/310 patients, P = 0.004). The majority of fatal outcome was due to cancerous diseases in both groups. No difference was observed concerning the long-term TE rate (12/310 vs. 4/80 patients, P = 0.75). Rhythm control failed in 25.9% of the patients, with no difference between the groups: 26.4% in group 1 vs. 23.7% in group 2 (P = 0.67). 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.
