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

INTRODUCTION AND OBJECTIVES

This report presents the findings of the 2018 Spanish Catheter Ablation Registry.

METHODS

Data collection was retrospective. A standardized questionnaire was completed by each of the participating centers.

RESULTS

Data sent by 100 centers were analyzed, with a total number of 16566 ablation procedures performed (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 re-entrant tachycardia (n=3525; 21.3%) and cavotricuspid isthmus (n=3425; 20.7%). A new peak was 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%. A total of 2.1% of the ablations were performed in pediatric patients.

CONCLUSIONS

The Spanish Catheter Ablation Registry enrolls systematically and continuously enrolls 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 percentage of complications.
