Abstract
INTRODUCTION AND OBJECTIVES
This report presents the findings of the 2019 Spanish Catheter Ablation Registry.
METHODS
Data collection was retrospective. A standardized questionnaire was filled by each of the participant centers.
RESULTS
Data sent by 102 centers were analyzed, with a total number of ablation procedures performed of 18 549 (the highest historically reported in this registry) for a mean of 181.9 ± 137.0 and a median of 144.5 procedures per center. The ablation targets most frequently treated were atrial fibrillation (n = 5164; 27.8%), cavotricuspid isthmus (n = 3925; 21.1%) and atrioventricular nodal reentrant tachycardia (n = 3768; 20.3%). A new peak is observed in the ablation of atrial fibrillation, increasing the distance from the other substrates. The overall success rate was again 91%. The rate of major complications was 1.9%, and the mortality rate was 0.03%. An electroanatomic mapping system was used in 44.5% of all procedures, with contact force-sensing irrigated catheters become the preferred for complex substrates, as atrial fibrillation (84.8%) or ventricular tachycardia (around 90%). 1.5% 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.
