Spanish Catheter Ablation Registry. 13th Official Report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2013)

Abstract

Introduction and objectives: This report presents the results of the 2013 Spanish Catheter Ablation Registry.

Methods: Data were collected using 2 systems: retrospectively by completing a dedicated form and prospectively by reporting to a central database. Each participating center chose 1 of the 2 data collection methods.

Results: Eighty centers voluntarily contributed data to the registry. A total of 11 987 ablation procedures were performed, with a mean (standard deviation) of 149 (105) procedures per center. The 3 main arrhythmic substrates treated were atrioventricular nodal reentrant tachycardia (n=2959; 24.6%), cavotricuspid isthmus ablation (n=2700; 22.5%), and atrial fibrillation (n=2201; 18.4%). The number of ventricular ablation procedures was similar to the 2012 activity, but there was a slight increase in procedures for scar-related postmyocardial infarction ventricular tachycardia. The success rate was 94.4%, major complications occurred in 1.8%, and the mortality rate was 0.03%.

Conclusions: In line with previous reports, the data from the 2013 registry show a continuing increase in the number of ablations performed. Overall, there was a high success rate and few complications. Ablation of complex substrates has continued to increase.
