Spanish Catheter Ablation Registry. 18th Official Report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2018)

Abstract Introduction and objectives This report presents the findings of the 2018 Spanish Catheter Ablation Registry. Methods Data collection was retrospective. A standardized questionnaire was filled by each one of the participant centers. Results Data sent by 100 centers were analyzed, with a total number of ablation procedures performed of 16 566 (the highest historically reported in this registry) for a mean of 165.5 ± 127.9 and a median of 119 procedures per center. The ablation targets most frequently treated were atrial fibrillation (n = 4234; 25.6%), atrioventricular nodal reentrant tachycardia (n = 3525; 21.3%) and cavotricuspid isthmus (n = 3425; 20.7%). A new peak is observed in the ablation of atrial fibrillation, increasing the distance from the other substrates. The overall success rate was 91%. The rate of major complications was 2.2%, and the mortality rate was 0.04%. 2.1% of the ablations were performed in pediatric patients. Conclusions The Spanish Catheter Ablation Registry enrolls systematically and uninterruptedly the ablation procedures performed in Spain, showing a progressive increasing in the number of ablations over the years with a high success rate and low percentages of complications.
