Registro Español de Ablación con Catéter. XIV Informe Oficial de la Sección de Electrofisiología y Arritmias de la Sociedad Española de Cardiología (2014) / Spanish Catheter Ablation Registry. 14th Official Report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2014)

Introducción y objetivos: Se detallan los resultados del Registro Español de Ablación con Catéter año 2014. Métodos: La recogida de datos se llevó a cabo mediante dos sistemas: retrospectivo, mediante cumplimentación de un formulario, y prospectivo, a través de una base de datos común. La elección de uno u otro fue voluntaria de cada uno de los centros. Resultados: Se recogieron datos de 85 centros. El número total de procedimientos de ablación fue 12.871, con una media de 149,5 ± 103 procedimientos. Los tres sustratos abordados con más frecuencia fueron la taquicardia intranodular (n = 3.026; 23,5%), la ablación del istmo cavotricuspídeo (n = 2.833; 22,0%) y la fibrilación auricular (n = 2.498; 19,4%). La ablación de arritmias ventriculares ha permanecido estable, con un ligero incremento de todos los sustratos ventriculares, en especial las taquicardias ventriculares idiopáticas y las asociadas a cicatriz tras infarto. La tasa total de éxito fue del 95%; la de complicaciones mayores, del 1,3% y la de mortalidad, del 0,02%. Conclusiones: En el registro del año 2014 se mantiene una línea de continuidad ascendente en el número de ablaciones realizadas y muestra, en líneas generales, una elevada tasa de éxito y bajo número de complicaciones. Continúa el aumento del abordaje de sustratos más complejos (AU)

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 (AU)
