The prevalence of atrial fibrillation (AF) increases with age. Although the efficacy cryoballoon ablation (CB-A) in patients AF has been demonstrated, data on this CB-A elderly are limited. aim study was to evaluate 1-year and safety aged ≥80 years compared those less than 80 years.A total 49 consecutive paroxysmal (PAF) who underwent were 241 <80 years. AF-free survival rate at 1 year procedural between groups.Median (25th, 75th quartile) age 83 (82, 85) older group 68 (61, 73) younger group. At follow-up, success did not significantly differ groups. In Cox regression analysis, related recurrence. Low-voltage areas more frequently observed control (39% vs 17%; P = .01). Fluoroscopy time procedure significantly. There no significant difference occurrence transient phrenic nerve palsy. No severe complications occurred either group, including procedure-related deaths, atrioesophageal fistula, cardiac tamponade, cerebrovascular embolic events.The results our showed that for PAF is a feasible safe even patients, similar complication rates when population.
