Spanish Catheter Ablation Registry. 14th Official Report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2014)

Abstract Introduction and objectives This report presents the findings of the 2014 Spanish Catheter Ablation Registry. Methods For data collection, each center was allowed to choose freely between 2 systems: retrospective, requiring the completion of a standardized questionnaire, and prospective, involving reporting to a central database. Results Data were collected from 85 centers. A total of 12 871 ablation procedures were performed, for a mean of 149.5 ± 103 procedures per center. The ablation targets most frequently treated were atrioventricular nodal reentrant tachycardia (n = 3026; 23.5%), cavotricuspid isthmus (n = 2833; 22.0%), and atrial fibrillation (n = 2498; 19.4%). The number of ablation procedures for ventricular arrhythmias was similar to that of 2013, but there was a slight increase in the treatment of all the ventricular substrates, especially those associated with idiopathic ventricular tachycardia and scarring following myocardial infarction. The overall success rate was 95%, the rate of major complications was 1.3%, and the mortality rate was 0.02%. Conclusions The 2014 registry shows that the number of ablation procedures performed continued its upward trend and that, overall, the success rate was high and the number of complications low. Ablation of complex conditions continued to increase.
