The first Latin American catheter ablation registry.

Abstract

El objetivo del estudio fue evaluar los resultados de la ablación transcateter de arritmias cardíacas en América Latina y establecer el primer registro latinoamericano de ablación transcateter. Fueron analizados retrospectivamente todos los procedimientos de ablación realizados entre el primero de enero y el 31 de diciembre del año 2012. Se obtuvieron datos de las fuentes de los centros participantes y de los resultados de 17 diferentes sustratos de ablación. Se recibieron y analizaron 15 099 procedimientos de 120 centros en 13 países participantes: Argentina, Bolivia, Brasil, Chile, Colombia, Cuba, El Salvador, Guatemala, México, Perú, República Dominicana, Uruguay y Venezuela. En conclusión, se considera que la Ablación con catéter en América Latina es efectiva y segura.

To assess the results of transcatheter ablation of cardiac arrhythmias in Latin America and establish the first Latin American transcatheter ablation registry. All ablation procedures performed between 1 January and 31 December 2012 were analysed retrospectively. Data were obtained on the characteristics and resources of participating centres (public or private institution, number of beds, cardiac surgery availability, type of room for the procedures, days per week assigned to electrophysiology procedures, type of fluoroscopy equipment, availability and type of electroanatomical mapping system, intracardiac echo, cryoablation, and number of electrophysiologists) and the results of 17 different ablation substrates: atrio-ventricular node reentrant tachycardia, typical atrial flutter, atypical atrial flutter, left free wall accessory pathway, right free wall accessory pathway, septal accessory pathway, right-sided focal atrial tachycardia, left-sided focal atrial tachycardia, paroxysmal atrial fibrillation, non-paroxysmal atrial fibrillation, atrio-ventricular node, premature ventricular complex, idiopathic ventricular tachycardia, post-myocardial infarction ventricular tachycardia, ventricular tachycardia in chronic chagasic cardiomyopathy, ventricular tachycardia in congenital heart disease, and ventricular tachycardias in other structural heart diseases. Data of 15 099 procedures were received from 120 centres in 13 participating countries (Argentina, Bolivia, Brazil, Chile, Colombia, Cuba, El Salvador, Guatemala, Mexico, Peru, Dominican Republic, Uruguay, and Venezuela). Accessory pathway was the group of arrhythmias most frequently ablated (31%), followed by atrio-ventricular node reentrant tachycardia (29%), typical atrial flutter (14%), and atrial fibrillation (11%). Overall success was 92% with the rate of global complications at 4% and mortality 0.05%. Catheter ablation in Latin America can be considered effective and safe.
