Comparison of long-term outcome between patients aged 〈 65 years vs. ≥ 65 years after atrial fibrillation ablation

Summary: | Background Atrial fibrillation (AF) is the most frequent arrhythmia, and its prevalence is increasing with aging. We aimed to com-pare the long-term outcome data of patients 〈 65 years vs.≥ 65 years who underwent catheter ablation (CA) for drug-refractory AF. MethodsConsecutive patients with primary pulmonary vein isolation performed between March 2001 and December 2011, and those who completeda 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-termoutcome data concerning mortality, thromboembolic events (TE) and success rates were compared between these groups. Results A totalnumber of 390 patients were included, group 1 contained 310 patients, and 80 patients in group 2. In group 2, patients had more often impairedrenal function (P 〈 0.001) and thyroid disease (P = 0.047). A total of fifteen patients died during the 6.63 ± 2.1 years of follow-up, with a sig-nificantly higher incidence in the older group (8/80 vs. 7/310 patients, P = 0.004). The majority of fatal outcome was due to cancerous dis-eases in both groups. No difference was observed concerning the long-term TE rate (12/310 vs. 4/80 patients, P = 0.75). Rhythm controlfailed 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), ConclusionsDespite growing prevalence of AF in aging population, the elderly patients are underrepresented in CA procedures. Similar clinical successand TE complication rate are observed between the age-groups. Our data suggest more liberal criteria might be applied while selecting pa-tients for AF ablation. |
