Periprocedural data and baseline characteristics were recorded retrospectively. A total of 61 243 procedures were included. There was an overall increase in the number of catheter ablations performed. From 2006, the number of atrial fibrillation (AF) ablations performed increased from 352 procedures in 2006 to 2609 procedures in 2020. Decreased procedural times were seen in catheter ablation of accessory pathway\/Wolff\u2013Parkinson\u2013White syndrome, atrial tachycardia (AT), atrioventricular nodal reentry tachycardia, cavotricuspid isthmus (CTI), AF, and atrioventricular junction. Between the time periods 2006\u201315 and 2016\u201320, median procedural time in AF ablations decreased from 180 to 140\u2005min (P &amp;lt; 0.001). There was a decreased trend in fluoroscopy time and median dose area product for all ablation procedures (P &amp;lt; 0.001). For AT, CTI, and AF, the cumulative probability of requiring a repeat ablation was significantly lower for procedures performed after January 2016 (P &amp;lt; 0.001).<\/jats:p>\n
