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

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.
