Registro Español de Ablación con Catéter. XIX Informe Oficial de la Asociación del Ritmo Cardiaco de la Sociedad Española de Cardiología (2019)

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.
