Abstract

Introduction and objectives

This article presents the findings of the 2012 Spanish Catheter Ablation Registry.

Methods

Data were collected in 2 ways: retrospectively using a standardized questionnaire, and prospectively using a central database. Each participating center selected its own preferred method of data collection.

Results

Seventy-four Spanish centers voluntarily contributed data to the survey. A total of 11 042 ablation procedures were analyzed, averaging 149 (103) per center. The 3 main conditions treated were atrioventricular nodal reentrant tachycardia (n=2842; 25.7%), cavotricuspid isthmus (n=2485; 23%), and accessory pathways (n=1999; 18%). Atrial fibrillation was the fourth most common substrate treated (n=1852; 17%), representing a slight increase. The number of ventricular arrhythmia ablation procedures was similar to that of 2011, but there was a decrease in procedures for ventricular tachycardia associated with postinfarction scarring. The overall success rate was 94.9%, major complications occurred in 1.9%, and the overall mortality rate was 0.04%.

Conclusions

Data from the 2012 registry show that the number of ablations performed continued to increase. Overall, they also show a high success rate and a low number of complications. Ablation of complex substrates continued to increase, particularly in the case of atrial fibrillation.

Resumen

Introducción y objetivos

Se detallan los resultados del Registro Nacional de Ablación del año 2012.

Métodos

La recogida de datos se llevó a cabo mediante dos sistemas. De manera retrospectiva con la cumplimentación de un formulario y de manera prospectiva a través de una base de datos común. La elección de una u otra fue voluntaria para cada uno de los centros.

Resultados

Se recogieron datos de 74 centros. El número total de procedimientos de ablación fue 11.042, con una media de 149 ± 103 procedimientos. Los tres sustratos abordados con más frecuencia fueron la taquicardia intranodular (n = 2.842; 25,7%), la ablación del istmo cavotricuspídeo (n = 2.485; 23%) y las vías accesorias (n = 1.999; 18%). El cuarto sustrato fue la ablación de fibrilación auricular (n = 1.852; 17%), que mostró un incremento del 21% con respecto a los datos de 2011. La ablación de arritmias ventriculares ha permanecido estable, pero han disminuido los procedimientos sobre las asociadas a cicatriz tras infarto. La tasa total de éxito fue del 94,9%; la de complicaciones mayores, del 1,9% y la de mortalidad, del 0,04%.

Conclusiones

El registro del año 2012 mantiene una línea de continuidad ascendente en el número de ablaciones realizadas y muestran, en líneas generales, una elevada tasa de éxito y bajo número de complicaciones. Continúa el aumento del abordaje de sustratos más complejos, especialmente de la fibrilación auricular.

INTRODUCTION

We present the Spanish Catheter Ablation Registry for 2011. Its publication completes 12 years of uninterrupted activity by the Spanish Society of Cardiology Working group on Electrophysiology and Arrhythmias.1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 This is a voluntary registry covering all of Spain and is published annually. The majority of Spanish electrophysiology laboratories participate, making it one of the few large-scale observational catheter ablation registries.

The main objectives of the

METHODS

As in previous years, 2 different systems were available for data collection: a prospective system and a retrospective system. The prospective approach uses a standardized database provided by the registry and requires patients to be added individually. The retrospective approach involves completing a standard questionnaire sent to all interventional electrophysiology laboratory in January 2013 and is also available on the Working Group on Electrophysiology and Arrhythmias website.12 Data

RESULTS

Following the general trend in recent years, there was an increase in both the number of participating centers and the total number of ablations performed. Of the 74 participating centers (Appendix 2), 60 (81.1%) belonged to the public health care system and 14 were private; for the first time, there were over 10 000 ablation procedures (Fig. 1).

The retrospective data collection system was once again the preferred method. Only 8 centers (10.8%) collected data prospectively.

The majority of the

DISCUSSION

Data from the 2012 catheter ablation registry show a continued increase in the number of participating centers, and thus the registry is increasingly representative of the situation in Spain. In total, 74 centers participated, surpassing the 66 centers that participated in 2011, thus setting a new record. The mean number of ablations per center increased slightly, and the total number of procedures easily surpassed the number performed in 2011.

Healthcare staff levels remained the same this

CONCLUSIONS

As in previous years, the Spanish Catheter Ablation Registry contains one of the largest samples of ablation procedures reported in international publications, surpassing the 9662 ablation procedures performed in 2011. Ever more complex substrates were treated, while maintaining a very high success rate with low rates of major complications and mortality.

Once again, the increase in the number and complexity of the ablations performed was not matched by an increased number of healthcare staff

Acknowledgements

The coordinators of the registry would like to express their thanks to all participants in the 2012 Spanish Catheter Ablation Registry who voluntarily and disinterestedly submitted the data on the procedures they performed. They also wish to extend special thanks to Cristina Plaza for her excellent and untiring administrative work.
