Spanish catheter ablation registry. 21st official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2021).

INTRODUCTION AND OBJECTIVES: The results of the 2021 Spanish catheter ablation registry are presented. METHODS: Data collection was carried out retrospectively by filling in and sending a specific form by the participating centers. RESULTS: Data from 93 centers (65 public, 28 private) were analyzed. A total of 17941 ablation procedures were reported with a mean of 193 ± 133 cases per centre. Recovery of activity from SARS-CoV-2 pandemic lockdown has led to a notable increase in the number of procedures (+2772 procedures, +18%) despite a small decrease in participating centers (4 centers less than in 2020). Atrial fibrillation ablation continues to be the leading procedure, with 5848 procedures (32,6%). Together with ablation of the cavotricuspid isthmus (3766; 21%) and atrioventricular nodal reentrant tachycardia (3132; 17,5%) they constitute the 3 most frequently approached substrates. The total success rate reported (94%) is similar to previous years with a similar rate of complications (2%) and mortality (0.07). A total of 401 procedures were performed in pediatric patients (3,8%). CONCLUSIONS: The Spanish catheter ablation registry systematically and continuously collects the national activity, which has recovered significantly from the SARS-CoV-2 pandemic impact in 2020. Success rate for 2021 remains high, with a low complication rate.

Registro español de ablación con catéter. XXI Informe oficial de la Asociación del Ritmo Cardiaco de la Sociedad Española de Cardiología (2021) Spanish catheter ablation registry. 21st official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2021)

Introducción y objetivos Se describen los resultados del Registro español de ablación con catéter correspondientes al año 2021, marcado por la recuperación de la actividad tras la pandemia de SARS-CoV-2. Métodos La recogida de datos fue restrospectiva mediante la cumplimentación y el envío de un formulario específico por los centros participantes. Resultados Se analizaron los datos de 93 centros (65 públicos, 28 privados). Se comunicaron 17.941 procedimientos de ablación con una media de 193 ± 133 y mediana de 171. La recuperación de la actividad tras el cierre por la pandemia de SARS-CoV-2 ha supuesto un marcado aumento de procedimientos (+2.772 casos, +18%) a pesar de un ligero descenso en el número de centros participantes (4 menos que en 2020). La ablación de la fibrilación auricular sigue siendo el procedimiento más frecuente, a distancia del resto de sustratos (5.848;32,6%). Junto con la ablación del istmo cavotricuspídeo (3.766;21%) y la taquicardia por reentrada intranodular (3.132;17,5%), constituye los 3 sustratos abordados con más frecuencia. Las tasas comunicadas de éxito (94%), complicaciones (2%) y mortalidad (0,07%) son similares a las de años previos. Se realizaron 401 procedimientos en pacientes pediátricos (el 3,8% del total). Conclusiones El Registro español de ablación con catéter recoge de manera sistemática e ininterrumpida la actividad nacional, y este año se ha observado una marcada recuperación de la actividad a pesar del persistente efecto de la pandemia de SARS-CoV-2. La tasa de éxito sigue manteniéndose elevada, con una baja tasa de complicaciones.

Spanish Catheter Ablation Registry. 20th Official Report of the Heart Rhythm Association of the Spanish Society of Cardiology (2020).

INTRODUCTION AND OBJECTIVES: This article reports the results of the 2020 Spanish Catheter Ablation Registry, a year marked by the SARS-CoV-2 pandemic. METHODS: Data were collected retrospectively through completion and return of a specific form by the participating centers. RESULTS: Data from 97 centers (67 public, 30 private) were analyzed. A total of 15 169 ablation procedures were reported with a mean of 155±117 and a median [interquartile range] of 115 [62-227]. Because of the SARS-CoV-2 pandemic, both procedures and participating centers markedly decreased (-3380 procedures,-18%) and there were 5 centers less than in 2019. The most common procedure continued to be atrial fibrillation ablation (4513; 30%), well ahead of the remaining substrates, followed by ablation of the cavotricuspid isthmus (3188; 21%), and intranodal re-entry tachycardia (2808; 18%). Ablation of these 3 substrates continued to form the bulk of the procedures. The total success rate was slightly lower than in previous years (88%) with a similar complication rate (n=309; 2%) and mortality (n=7; 0.04%). A total of 243 procedures were performed in pediatric patients (1.6%). CONCLUSIONS: The Spanish Catheter Ablation Registry systematically and continuously reflects the national trajectory, which, in 2020, was markedly affected by the SARS-CoV-2 pandemic. Although slightly lower than in previous years, the success rate remained high, with a low complication rate.

Spanish Pacemaker Registry. 18th Official Report of the Cardiac Pacing Section of the Spanish Society of Cardiology (2020).

INTRODUCTION AND OBJECTIVES: This report describes the cardiac pacing activity performed in Spain in 2020, including the number and type of implanted devices, demographic and clinical factors, and data on remote monitoring. METHODS: Information consisted of the European Pacemaker Patient Card, data submitted to the cardiodispositivos.es online platform, the databases of participating centers, and supplier-reported data. RESULTS: A total of 14 662 procedures were registered from 102 hospitals, representing 39.2% of the estimated activity. The implantation rates of conventional and low-energy resynchronization pacemakers were 759 and 31 units per million population, respectively. In all, 520 leadless pacemakers were implanted, 70 with atrioventricular synchrony. The mean age at implantation was high (78.8 years), and the most frequent electrocardiographic change was atrioventricular block. There was a predominance of dual-chamber pacing mode but VVI/R single-chamber pacing was used in 19% of patients in sinus rhythm, depending on age and sex. Remote monitoring capability was present in 18.5% of implanted conventional pacemakers and 45.6% of low-energy resynchronization pacemakers, although registration in this system increased by 53% in 2020. CONCLUSIONS: In 2020, in the context of the SARS-CoV-2 pandemic, the number of implanted conventional pacemakers decreased by 8% and cardiac resynchronization therapy by 4.6%. The number of leadless pacemakers increased by 16.5%. Sequential pacing was predominant, influenced by age and sex. Home monitoring played a fundamental role as a mode of follow-up in this SARS-CoV-2 pandemic year.

Registro Español de Marcapasos. XVIII Informe Oficial de la Sección de Estimulación Cardiaca de la Sociedad Española de Cardiología (2020)

Resumen Introducción y objetivos Se describe la actividad de estimulación cardiaca realizada en España en 2020: cuantía y tipo de dispositivos, factores demográficos y clínicos y datos sobre monitorización a distancia. Métodos Se utilizan como fuentes de información la Tarjeta Europea de paciente portador de Marcapasos, la plataforma online cardiodispositivos.es, las bases de datos propias de centros y los datos facilitados por las empresas proveedoras. Resultados Se registran 14.662 procedimientos de 102 hospitales, lo que supone el 39,2% de la actividad estimada. La tasa de marcapasos convencionales y resincronizadores de baja energía es de 759 y 31 unidades/millón respectivamente. Se implantan 520 marcapasos sin cables, 70 con sincronía auriculoventricular. La media de edad al implante es elevada (78,8 años) y el bloqueo auriculoventricular, la alteración electrocardiográfica más frecuente. Predomina el modo de estimulación bicameral, aunque en el 19% de los pacientes en ritmo sinusal se realiza una estimulación monocameral VVI/R, condicionada por edad y sexo. Se incluyen en programa de monitorización a distancia el 18,5% de los marcapasos implantados y el 45,6% de los resincronizadores de baja energía, aunque aumentan en un 53% las altas en este sistema durante 2020. Conclusiones En 2020, en contexto de la pandemia por SARS-CoV-2, disminuye el número de marcapasos convencionales implantados un 8% y el de terapias se resincronización cardiaca, un 4,6%. Aumenta el número de marcapasos sin cables un 16,5%. Predomina la estimulación secuencial, influida por edad y sexo. La monitorización domiciliaria cobra un papel fundamental como modo de seguimiento en el año de la pandemia por SARS-CoV-2.
