Why the study?
The number of catheter ablations is growing and techniques are improving, but contemporary data from large real-world populations remain scarce.
How have procedural characteristics and outcomes of catheter ablation for arrhythmias evolved over a 15-year period in a nationwide registry?
Population
61 243 catheter ablation procedures in patients >18 years of age in Sweden
Comparison
Catheter ablation procedures over time (2006–15 vs 2016–20)
Design
Nationwide registry-based retrospective study

Registry trends link rising ablation volumes to shorter procedures and fewer repeats for AF/AT/CTI; extends observational benchmarks but leaves causal effects open for prospective study.
How have procedural characteristics and outcomes of catheter ablation for arrhythmias evolved over a 15-year period in a nationwide registry?
Over a 15-year period, catheter ablation procedures have increased in volume while demonstrating improved efficiency with shorter procedural times, lower radiation exposure, and a reduced need for repeat procedures.
