They were stratified into six age groups, ranging from\u00a0&amp;lt;65 to\u00a0\u226585 years, in 5-year increments. A cut-off of 80 years was set for dividing participants into two groups. The primary endpoints included procedure-related complications and 1-year arrhythmia recurrence after a 3-month blanking period. Patients\u00a0\u226580 years constituted 7.2% of procedures in 2017, which significantly increased to 9.6% by 2020 (P\u00a0&amp;lt;\u00a00.001). This older group predominantly comprised women with smaller stature and body mass index, a higher prevalence of paroxysmal AF, and a higher rate of initial ablation procedures. The overall complication rate was 2.8%, showing a positive correlation with age (P\u00a0&amp;lt;\u00a00.001), peaking at 4.3% for patients\u00a0\u226585 years. Older age remained a significant independent risk factor for complications (odds ratio: 1.36 [1.24, 1.49], P\u00a0&amp;lt;\u00a00.001). Cardiac tamponade, ischaemic stroke, and sick sinus syndrome were more common in the elderly. The recurrence rate in the total population was 16.0% and did not differ significantly between age groups (log-rank P\u00a0=\u00a00.473), remaining consistent even after adjusting for multiple variables.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Although age increases complication
