Registro de intervenciones en pacientes con cardiopatía congénita de la Sociedad Española de Cirugía Cardiovascular y Endovascular: 2021 y retrospectiva de la última década

Resumen La Sociedad Española de Cirugía Cardiovascular y Endovascular, de manera conjunta al registro general de actividad 2021, muestra sus datos de actividad en pacientes con cardiopatía congénita del período temporal 2012-2021, basado en un registro voluntario y anónimo de los centros participantes. En 2021, aún marcado por las secuelas de la pandemia COVID-19, persiste el descenso de actividad quirúrgica en cardiopatías congénitas (CC) del 2020 respecto a los años previos. Presentamos agrupados los datos de actividad de la última década, para reflejar mejor nuestros resultados con estas patologías relativamente infrecuentes. En este tiempo se realizaron en España 20.139 cirugías de CC, que suponen el 9,5% de la cirugía cardiovascular mayor realizada en nuestro país durante ese tiempo. El 81,5% de las cirugías congénitas se hicieron con circulación extracorpórea y el 18,5% restante sin ella. Destacamos las intervenciones neonatales y en adultos, que asocian elevada complejidad y suponen, respectivamente, el 18% y el 21% de la actividad total. Las CC operadas más prevalentes continúan siendo los defectos septales en los casos que requieren circulación extracorpórea y los ductus en pacientes operados sin circulación extracorpórea. Los datos se presentan ajustados a la escala Aristóteles básico de riesgo quirúrgico preoperatorio. La mortalidad observada en cirugías con circulación extracorpórea fue del 3,07% (Aristóteles: 6,29), y en cirugías sin circulación extracorpórea, del 2,25% (Aristóteles: 4,82). Nuestro registro nacional de actividad quirúrgica en CC muestra buenos resultados, permite establecer comparaciones a nivel nacional e internacional, para diseñar estrategias de mejora, fijar objetivos y aumentar la calidad de nuestras actuaciones. The Spanish Society of Cardiovascular & Endovascular Surgery presents the 2012-2021 report of the activity in congenital cardiovascular surgery, based on a voluntary and anonymous registration involving most of Spanish centres. This article is complementary to the 2021 cardiovascular surgery annual report, and they are published together. In 2021, still marked by the aftermath of the COVID-19 pandemic, the decline in our 2020 congenital activity persists, compared with previous years. We included data from the previous 10years, in order to obtain real information related to our activity with these relatively scarce pathologies. In the last decade, a total of 20,139 congenital heart surgeries were performed, accounting for 9.5% of all major surgery (congenital +acquired) performed in Spain during that period. Of these surgeries, 81.5% of them required extracorporeal circulation and 18.5% not. We highlight the interventions in neonates and adult patients, which mean respectively 18% and 21% of our whole activity and are a real challenge. The most prevalent congenital heart pathologies operated on were: septal defects in cases requiring extracorporeal circulation, and ductus in patients without extracorporeal circulation. The presented data are adjusted to the basic Aristotle score of preoperative surgical risk. The observed mortality of surgeries with extracorporeal circulation was 3.07% (Aristotle: 6.29), and without cardiopulmonary bypass 2.25% (Aristotle: 4.82). Our national registry of surgical activity in congenital heart disease shows good results, allows us to compare ourselves within a national and international framework, design improvement strategies, set objectives and improve the quality of our actions.

Cirugía cardiovascular en España en el año 2021. Registro de intervenciones de la Sociedad Española de Cirugía Cardiovascular y Endovascular

Resumen El presente registro aporta los datos correspondientes a la actividad de cirugía cardiovascular realizada en España durante el año 2021. Se trata de un registro anónimo y voluntario de datos agregados en el que han participado hospitales del territorio nacional, transfiriendo sus datos a la Sociedad Española de Cirugía Cardiovascular y Endovascular (SECCE). Se comunican, por trigésimo tercer año consecutivo los datos de la actividad nacional. El registro de 2021 puede tener valor para analizar la posible recuperación de la actividad después de la pandemia de SARS-CoV2 sobre la actividad en cirugía cardiaca en nuestro país. En el año 2021 comunicaron su actividad 58 hospitales frente a los 60 que compartieron datos en 2020. En total, se realizaron 29.319 intervenciones, con 19.229 procedimientos de cirugía cardiaca mayor. De estos, 16.863 procedimientos fueron realizados con circulación extracorpórea, 17.616 fueron de enfermedad adquirida y 1.613 de enfermedad congénita. Además, se registraron 2.637 intervenciones de cirugía vascular periférica.Como en años previos, tanto la cirugía cardiaca congénita como el trasplante cardiaco disponen de su propio registro. Dentro de los diferentes apartados de cirugía cardiaca mayor se realizaron: 7.673 procedimientos de cirugía valvular aislada, 1.523 de cirugía valvular combinada, 4.287 procedimientos de revascularización, 2159 de cirugía de aorta y 654 procedimientos de válvulas transcatéter. En comparación con 2020, observamos un aumento generalizado de la actividad, que fue de 7,9% con respecto de dicho año previo, pero con una reducción de más del 12% con respecto de la media de los 9 años anteriores (2012-2020). This report provides the data corresponding to the cardiovascular surgery activity performed in Spain during 2021. The Spanish Registry is an anonymous and voluntary registry of aggregated data in which hospitals in the national territory have taken part, transferring their data to the Spanish Society of Cardiovascular and Endovascular Surgery (SECCE). For the thirty-third consecutive year, the national activity data is reported. The 2021 registry may be of some value for analyzing the possible recovery of the cardiac surgery activity after the SARS-CoV2 pandemic in our country.In 2021, 58 hospitals reported their activity compared to the 60 that shared their data in 2020. In total, 29,319 interventions were performed, with 19,229 major cardiac surgical procedures. Of these, 16,863 procedures were performed with cardiopulmonary bypass, 17,616 were indicated because of acquired disease and 1,613 for congenital disease. In addition, 2,637 peripheral vascular surgical interventions were registered.As in previous years, both congenital heart surgery and heart transplantation activity and outcomes will be reported in separate registries. Within the different types of major cardiac surgical procedures, the following were performed: 7,673 isolated valve procedures, 1,523 combined valve and coronary surgeries, 4,287 coronary revascularization procedures, 2,159 aortic surgeries, and 654 transcatheter valve implantations. Compared to 2020, we observed a general increase in activity, which was 7.9% compared to the previous year, but with a reduction of more than 12% compared to the mean of the previous 9 years (2012-2020).

Spanish cardiac catheterization and coronary intervention registry. 31st official report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2021).

INTRODUCTION AND OBJECTIVES: The Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) presents its annual activity report for 2021. METHODS: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company, together with the members of the ACI-SEC. RESULTS: A total of 121 centers participated (83 public and 38 private). Compared to 2020, both diagnostic coronary angiograms and percutaneous coronary interventions (PCI) increased by 11,4% and 10,3%, respectively. The radial approach was the most used access (92,8%). Primary PCI also increased by 6.2% whereas rescue PCI (1,8%) and facilitated PCI (2,4%) were less frequently conducted. Transcatheter aortic valve implantation was one of the interventions with the most relevant increase. A total of 5720 transcatheter aortic valve implantation procedures were conducted with an increase of 34,9% compared to 2020 (120 per million in 2021 and 89,4 per million in 2020). Other structural interventions like transcatheter mitral or tricuspid repair, left atrial appendage occlusion and patent foramen oval closure also experienced a significant increase. CONCLUSIONS: The 2021 registry demonstrates a clear recovery of the activity both in coronary and structural interventions showing a relevant increase compared to 2020, the year of the COVID-19 pandemic.

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.

Spanish implantable cardioverter-defibrillator registry. 18th official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2021).

INTRODUCTION AND OBJECTIVES: This article presents the data corresponding to implantable cardioverter-defibrillator (ICD) implantations in Spain in 2021. METHODS: The data were drawn from implanting centers, which voluntarily completed a data collection sheet during the procedure. RESULTS: In 2021, 7496 implant data sheets were received, compared with 7743 reported by Eucomed (European Confederation of Medical Suppliers Associations), indicating that data were collected from 96.8% of the devices implanted in Spain. Data completion ranged from 99.9% for "name of implanting hospital" to 8.9% for "implanting hospital". In 2021, 199 hospitals participated in the registry, exceeding the figures of previous years, with around 170 participating hospitals. The total rate of registered implants was 158/million inhabitants (163 according to Eucomed), making 2021 the year with the highest activity. However, the registry continues to show significant differences among the various autonomous communities and the lowest implantation rate of all the European countries participating in Eucomed. CONCLUSIONS: The Spanish implantable cardioverter-defibrillator registry for 2021 recorded an increase in the number of ICD implantations, reflecting the recovery of hospital activity after the initial impact of the COVID-19 pandemic in 2020. Although the total number of implants has increased in Spain, figures are still much lower than the European Union average, with differences persisting among Spanish autonomous communities.

Resumen Introducción y objetivos La Asociación de Cardiología Intervencionista de la Sociedad Española de Cardiología (ACI-SEC) presenta su informe anual de actividad del año 2021. Métodos Todos los centros españoles con laboratorio de hemodinámica recibieron una invitación para participar en el registro. La recogida de datos se realizó a través de un cuestionario telemático. Una empresa externa se encargó del análisis de los datos, que fueron revisados por los miembros actuales de la Junta de la ACI-SEC. Resultados Participaron 121 centros (83 públicos y 38 privados). El número de estudios diagnósticos se incrementó en un 11,4% en comparación con 2020. También se recuperaron las cifras de intervención coronaria percutánea (ICP), con un incremento del 10,3% respecto al año previo. El abordaje radial fue el más utilizado para la ICP (92,9%). La ICP primaria experimentó un crecimiento del 6,2% y, por el contrario, las angioplastias de rescate (1,8%) o facilitada/planificada (2,4%) se redujeron respecto a 2020. Uno de los incrementos más significativos de todo el registro fue en el número de implantes percutáneos de válvula aórtica, que se sitúan en 5.720 procedimientos, lo que representa un aumento del 34,9% respecto a 2020. El número de implantes por millón de habitantes también se incrementó hasta los 120 por millón (89,4 en 2020). Otros procedimientos estructurales, como los de reparaciones mitral y tricuspídea, cierre de orejuela o de foramen oval permeable, también tuvieron un aumento importante respecto a 2020. Conclusiones El Registro español de la ACI-SEC 2021 demuestra una clara recuperación de la actividad en general respecto a 2020, el año de la pandemia de la COVID-19.

Conclusions The 2021 registry demonstrates a clear recovery of the activity both in coronary and structural interventions showing a relevant increase compared to 2020, the year of the COVID-19 pandemic.

Registro español de desfibrilador automático implantable. XVIII informe oficial de la Asociación del Ritmo Cardiaco de la Sociedad Española de Cardiología (2021)

Resumen Introducción y objetivos Se presentan los datos correspondientes a los implantes de desfibrilador automático implantable (DAI) en España en el año 2021. Métodos Los datos provienen de los centros implantadores, que cumplimentaron voluntariamente una hoja de recogida de datos durante el implante. Resultados En 2021 se recibieron 7.496 formularios de implante, frente a los 7.743 comunicadas por Eucomed (European Confederation of Medical Suppliers Associations), lo que implica que se han recogido datos del 96,8% de los dispositivos implantados en España. El cumplimiento osciló entre el 99,9% en el campo «nombre del hospital implantador» y el 8,9% en la variable «hospital de referencia». En 2021, 199 hospitales han participado en el registro, lo cual supera las cifras de los años previos en que el número de participantes osciló alrededor de 170 hospitales. La tasa total de implantes registrados fue 158/millón de habitantes (163 según Eucomed), lo que la sitúa como el año con mayor actividad. Sin embargo, el registro sigue mostrando diferencias importantes entre las comunidades autónomas y la tasa de implante más baja de todos los países europeos participantes en Eucomed. Conclusiones El Registro español de desfibrilador automático implantable del año 2021 recoge un incremento en el número de implantes de DAI y refleja la recuperación de la actividad hospitalaria tras el impacto inicial de la pandemia por COVID-19 durante 2020. A pesar del incremento en el número total de implantes en España, este sigue siendo muy inferior a la media de la Unión Europea y persisten las diferencias entre las comunidades autónomas españolas. Introduction and objectives This article presents the data corresponding to implantable cardioverter-defibrillator (ICD) implantations in Spain in 2021. Methods The data were drawn from implanting centers, which voluntarily completed a data collection sheet during the procedure.

Data completion ranged from 99.9% for “name of implanting hospital” to 8.9% for “implanting hospital”. In 2021, 199 hospitals participated in the registry, exceeding the figures of previous years, with around 170 participating hospitals. The total rate of registered implants was 158/million inhabitants (163 according to Eucomed), making 2021 the year with the highest activity. However, the registry continues to show significant differences among the various autonomous communities and the lowest implantation rate of all the European countries participating in Eucomed. Conclusions The Spanish implantable cardioverter-defibrillator registry for 2021 recorded an increase in the number of ICD implantations, reflecting the recovery of hospital activity after the initial impact of the COVID-19 pandemic in 2020. Although the total number of implants has increased in Spain, figures are still much lower than the European Union average, with differences persisting among Spanish autonomous communities.

Spanish heart transplant registry. 33rd official report of the Heart failure Association of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: This report updates the annual data of the Spanish Heart Transplant Registry with the procedures performed in 2021. METHODS: We describe the clinical profile, therapeutic characteristics and outcomes in terms of survival of the procedures performed in 2021. Their temporal trends are updated for the 2012 to 2020 period. RESULTS: In 2021, 302 heart transplants were performed (8.6% increase versus 2020). The tendency in 2021 confirmed that of prior years, with fewer urgent transplants and a preference for the use of ventricular assist devices. The remaining characteristics and survival showed a clear trend toward stability in the last decade. Compared with 2019, the SARS-CoV-2 pandemic (2020 and 2021) did not affect short- or long-term survival. CONCLUSIONS: In 2021, transplant activity returned to prepandemic levels. The SARS-CoV-2 pandemic did not significantly affect transplant outcomes. The main transplant features and outcomes have clearly stabilized in the last decade.

Registro Español de Trasplante Cardiaco. XXXIII Informe Oficial de la Asociación de Insuficiencia Cardiaca de la Sociedad Española de Cardiología

Resumen Introducción y objetivos Se actualizan los datos anuales de Registro Español de Trasplante Cardiaco con los hallazgos de los procedimientos realizados en 2021. Métodos Se describen las principales características clínicas, del tratamiento recibido y de los resultados en términos de supervivencia del año 2021 y las tendencias en el periodo 2012-2020. Resultados En 2021 se han realizado 302 trasplantes cardiacos (un 8,6% más que el año anterior). En 2021 se ha confirmado la tendencia observada en años anteriores a una disminución de los trasplantes urgentes y a la realización de estos mayoritamente con dispositivos de asistencia ventricular. Las demás características y los resultados en términos de supervivencia muestran una clara tendencia a la estabilización en la última década. Respecto a 2019, en los años de la pandemia por SARS-CoV-2 (2020 y 2021) no se detecta un impacto relevante en los resultados en la fase aguda tras el trasplante y en la serie histórica. Conclusiones En 2021 se ha recuperado la actividad de trasplante hasta cifras previas a la pandemia por SARS-CoV-2, que no ha tenido un impacto global significativo en los resultados. Las características del procedimiento y los resultados muestran una clara tendencia a la estabilización en la última década.

Cirugía cardiovascular en España en el año 2020. Registro de intervenciones de la Sociedad Española de Cirugía Cardiovascular y Endovascular

Resumen El presente registro aporta los datos correspondientes a la actividad de cirugía cardiovascular realizada en España durante el año 2020. Se trata de un registro anónimo y voluntario de datos agregados en el que han participado 60 hospitales del territorio nacional, transfiriendo sus datos a la Sociedad Española de Cirugía Cardiovascular y Endovascular (SECCE). Se comunican, por trigésimo segundo año consecutivo los datos de la actividad nacional. El de este año es, sin duda, un registro singular e importante para valorar el impacto que tuvo la pandemia de SARS-CoV-2 sobre la actividad en cirugía cardiaca en nuestro país, más allá de los datos que han sido ya comunicados en este sentido en diversos estudios comunicados por la SECCE. En el año 2020 comunicaron su actividad 60 hospitales frente a los 57 que compartieron datos en 2019. En total, se realizaron 27.017 intervenciones totales, con 17.880 procedimientos de cirugía cardiaca mayor. De estas, 15.534 procedimientos fueron realizados con circulación extracorpórea (CEC). Los 17.880 procedimientos de cirugía cardiaca mayor se pueden desglosar en 16.271 de enfermedad adquirida y 1.609 de enfermedad congénita. Además, se registraron 2.462 intervenciones de cirugía vascular periférica en los diferentes servicios de cirugía cardiovascular. Como en registros previos, tanto la cirugía cardiaca congénita como el trasplante cardiaco disponen de su propio registro. Dentro de los diferentes apartados de cirugía cardiaca mayor se realizaron: 6.766 procedimientos de cirugía univalvular aislada, 1.609 de cirugía valvular combinada, 4.219 procedimientos de revascularización, 1.912 de cirugía de aorta y 502 procedimientos de válvulas transcatéter (TAVI). En comparación con 2019, observamos un descenso generalizado de la actividad, siendo más marcado para la cirugía valvular (−21% para univalvular, −52% para TAVI transapical) y menos para cirugía coronaria (−11%). Además, informamos de diversos datos de distribución geográfica de la actividad quirúrgica a nivel nacional. The Spanish Society of Cardiovascular and Endovascular Surgery (SECCE) reports the results of the 2020 registry of the surgical activity in our country. This year represents the 33rd consecutive year in which this report is published. The participation in this registry is anonymous and voluntary, and it is based on the analysis of the information gathered from 60 centers with activity in cardiovascular surgery in our country, and the confidentiality of the individual data of each center is warranted. It is certainly an important issue in which COVID-19 impact on cardiac surgical activity is analysed. The registry reports the global activity in our country, the observed mortality and the estimated mortality risk, stratified in different types of procedures. In 2020, 27.017 interventions were performed, with 17.880 of major heart surgery. Among these, 16.271 procedures were adult cardiac surgery and 1.609 of congenital heart surgery. Congenital heart surgery and cardiac transplant registries are specifically analysed in their corresponding reports. Among the 17.311 procedures of acquired major cardiac surgery, isolated valve surgery was predominant (6.766 procedures), followed by coronary by-pass surgery (4.239), aorta surgery (1.902). TAVI procedures were performed in 502 cases. Coronary surgery showed a 11% decrease in activity. The information derived from this national registry allows to know the state-of-the-art of the surgical specialty in our country, through the knowledge of the surgical activity, the risk profile and the observed results, which is a keystone for an adequate evaluation of the quality of the health care that we deliver to the patients affected with cardiovascular pathologies. Risk adjusted mortality seems adequately adjusted, though important local differences are observed.

Registro de intervenciones en pacientes con cardiopatía congénita de la Sociedad Española de Cirugía Cardiovascular y Endovascular: 2020 y retrospectiva de los 9 años previos

Resumen La Sociedad Española de Cirugía Cardiovascular y Endovascular muestra sus datos de actividad en pacientes con cardiopatía congénita (CC) del período temporal 2012-2020, basado en un registro voluntario y anónimo de los centros participantes. Este manuscrito complementa al registro general de actividad 2020 y ambos se publican conjuntamente. En 2020, marcado por la pandemia COVID-19 en todos los ámbitos sanitarios, observamos un descenso de actividad quirúrgica en CC del 14% respecto al año previo. Agrupamos los datos de actividad de los últimos 9 años, porque reflejan mejor nuestros resultados con estas enfermedades relativamente infrecuentes. En este período se realizaron en España 18.526 cirugías de CC, que suponen un 9,6% de la cirugía mayor (congénita + adquirida) realizada en nuestro país durante ese tiempo. El 81% de las cirugías congénitas se hicieron con circulación extracorpórea y el 19% restante sin ella. Destacamos las intervenciones en neonatos y en adultos que asocian elevada complejidad, suponiendo respectivamente un 19 y 21% de la actividad total. Las CC operadas más prevalentes continúan siendo los defectos septales dentro de los casos que requieren circulación extracorpórea, y los ductus en pacientes operados sin circulación extracorpórea. Los datos se presentan ajustados a la escala Aristóteles básico de riesgo quirúrgico preoperatorio. La mortalidad observada en cirugías con circulación extracorpórea fue del 3,1% (Aristóteles-6,48), y en cirugías sin circulación extracorpórea del 2,41% (Aristóteles-4,81). Este registro muestra detalladamente nuestros datos de actividad quirúrgica en CC, y permite comparaciones tanto a nivel nacional como internacional, para establecer estrategias de mejora de nuestros resultados. The Spanish Society of Cardiovascular & Endovascular Surgery presents the 2012-2020 report of the activity in congenital cardiovascular surgery, based on a voluntary and anonymous registration involving the most of Spanish centres. This article is complementary to the 2020 cardiovascular surgery annual report, and they are published together. In 2020, seriously damaged by the COVID-19 pandemic related to all sanitary fields, we observe a 14% drop in our congenital activity compared with 2019. Data from the previous 9 years are included, in order to obtain real information related to our activity in these relatively scarce pathologies. In the last nine years, a total of 18526 congenital heart surgeries were performed, accounting for 9.6% of major surgery (congenital + acquired) performed in Spain during that period. Of these surgeries, 81% of them required extracorporeal circulation and 19% not. We highlight the interventions in neonates and adult patients, which represent respectively 19% and 21% of the whole activity and are a real challenge. The most prevalent congenital heart pathologies operated on were septal defects in cases requiring extracorporeal circulation, and ductus in patients not requiring extracorporeal circulation. The presented data are adjusted to the basic Aristotle score of preoperative surgical risk. The observed mortality of surgeries with extracorporeal circulation was 3.1% (Aristotle-6.48), and without cardiopulmonary bypass 2.41% (Aristotle-4.81). This data analysis shows accurate and reliable information about our surgery for congenital heart disease and allow us to compare ourselves within an international framework, and to organize strategies directed to improve our results.

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.

Spanish Implantable Cardioverter-defibrillator Registry. 17th Official Report of the Heart Rhythm Association of the Spanish Society of Cardiology (2020).

INTRODUCTION AND OBJECTIVES: We present the data corresponding to implantable cardioverter-defibrillator (ICD) implants in Spain in 2020. METHODS: The data in this registry were drawn from implantation centers, which voluntarily completed a data collection sheet. RESULTS: In 2020, 7056 implant sheets were received compared with 7106 reported by Eucomed (European Confederation of Medical Suppliers Associations), indicating that data were collected from 99% of the devices implanted in Spain. Completion of the implant sheet ranged from 99.8% for the field "name of the implanting hospital" to 2.6% for the variable "referral hospital". A total of 173 hospitals performed ICD implants and participated in the registry, which is a similar figure to that in 2019 (n=172). The total rate of registered implants was 149/million inhabitants (150 according to Eucomed), revealing a slight reduction in implants in Spain in 2020 as a result of the impact of the COVID-19 pandemic. This reduction was uneven among the autonomous communities. CONCLUSIONS: The Spanish Implantable Cardioverter Defibrillator Registry for 2020 shows an improvement in the rate of implants reported and a reduction in the number of ICD implants, which likely reflects the decrease in hospital activity not related to the treatment of COVID-19 infection. Similar to previous years, the total number of implants in Spain is still much lower than the average for the European Union, with an increase in the differences between Spanish autonomous communities.

Spanish Heart Transplant Registry. 32nd Official Report of the Heart Failure Association of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: The present report updates the main characteristics and outcomes of heart transplants in Spain to 2020. METHODS: We describe the main features of recipients, donors, surgical procedure, and immunosuppression in 2020. We also analyze the temporal trends of these characteristics and outcomes (survival) for the period 2011 to 2019. RESULTS: In 2020, 278 heart transplants were performed (7.3% decrease vs 2019). The findings in 2020 confirmed previous observations of an increase in pretransplant sternotomy, a slight decrease in urgent transplants carried out with ventricular assist devices, a slight decrease in donor age, an increase in the use of allografts with previous arrest, and a decrease in ischemia time. Survival continued to improve in recent triennia, reaching 82.0% at 1 year in the period 2017 to 2019. CONCLUSIONS: The slight decrease in the number of heart transplants performed in 2020 in Spain, most likely due to the SARS-CoV-2 pandemic, did not change the main characteristics of the procedure. No change was observed in the tendency to improved survival.

Encephalopathy and encephalitis during acute SARS-CoV-2 infection. Spanish Society of Neurology COVID-19 Registry. / Encefalopatías y encefalitis durante la infección aguda por SARS-CoV2. Registro de la Sociedad Española de Neurología SEN COVID-19.

OBJECTIVES: Since the beginning of the COVID-19 pandemic, the Spanish Society of Neurology has run a registry of patients with neurological involvement for the purpose of informing clinical neurologists. Encephalopathy and encephalitis were among the most frequently reported complications. In this study, we analyse the characteristics of these complications. PATIENTS AND METHODS: We conducted a retrospective, descriptive, observational, multicentre study of patients with symptoms compatible with encephalitis or encephalopathy, entered in the Spanish Society of Neurology's COVID-19 Registry from 17 March to 6 June 2020. RESULTS: A total of 232 patients with neurological symptoms were registered, including 51 cases of encephalopathy or encephalitis (21.9%). None of these patients were healthcare professionals. The most frequent syndromes were mild or moderate confusion (33%) and severe encephalopathy or coma (9.8%). The mean time between onset of infection and onset of neurological symptoms was 8.02 days. Lumbar puncture was performed in 60.8% of patients, with positive PCR results for SARS-CoV-2 in only one case. Brain MRI studies were performed in 47% of patients, with alterations detected in 7.8% of these. EEG studies were performed in 41.3% of cases, detecting alterations in 61.9%. CONCLUSIONS: Encephalopathy and encephalitis are among the complications most frequently reported in the registry. More than one-third of patients presented mild or moderate confusional syndrome. The mean time from onset of infection to onset of neurological symptoms was 8 days (up to 24hours earlier in women than in men). EEG was the most sensitive test in these patients, with very few cases presenting alterations in neuroimaging studies. All patients treated with boluses of corticosteroids or immunoglobulins progressed favourably.

Atrial fibrillation in patients with COVID-19. Usefulness of the CHA2DS2-VASc score: an analysis of the international HOPE COVID-19 registry.

INTRODUCTION AND OBJECTIVES: Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2. Atrial fibrillation (AF) is common in acute situations, where it is associated with more complications and higher mortality. METHODS: Analysis of the international HOPE registry (NCT04334291). The objective was to assess the prognostic information of AF in COVID-19 patients. A multivariate analysis and propensity score matching were performed to assess the relationship between AF and mortality. We also evaluated the impact on mortality and embolic events of the CHA2DS2-VASc score in these patients. RESULTS: Among 6217 patients enrolled in the HOPE registry, 250 had AF (4.5%). AF patients had a higher prevalence of cardiovascular risk factors and comorbidities. After propensity score matching, these differences were attenuated. Despite this, patients with AF had a higher incidence of in-hospital complications such as heart failure (19.3% vs 11.6%, P=.021) and respiratory insufficiency (75.9% vs 62.3%, P=.002), as well as a higher 60-day mortality rate (43.4% vs 30.9%, P=.005). On multivariate analysis, AF was independently associated with higher 60-day mortality (hazard ratio, 1.234; 95%CI, 1.003-1.519). CHA2DS2-VASc score acceptably predicts 60-day mortality in COVID-19 patients (area ROC, 0.748; 95%CI, 0.733-0.764), but not its embolic risk (area ROC, 0.411; 95%CI, 0.147-0.675). CONCLUSIONS: AF in COVID-19 patients is associated with a higher number of complications and 60-day mortality. The CHA2DS2-VASc score may be a good risk marker in COVID patients but does not predict their embolic risk.

The Civil Registry in the first four months of the Covid-19 pandemic in Brazil: a comparative study between deaths by month of occurrence and by month of registration / O Registro Civil nos quatro primeiros meses da pandemia de Covid-19 no Brasil: estudo comparativo entre óbitos por mês de ocorrência e de registro / El Registro Civil en los primeros cuatro meses de la pandemia de covid-19 en Brasil: un estudio comparativo entre muertes por mes de ocurrencia y por mes de registro

O Registro Civil fornece informações aos estudos demográficos sobre mortalidade, fecundidade e nupcialidade. Questões têm surgido sobre o registro dos óbitos quando as causas de morte decorrem da Covid-19. A notificação pode acontecer com atraso. Com base nas informações disponibilizadas pelo Registro Civil de óbitos pela Covid-19, discriminados por dois grupos - data de registro e data de ocorrência -, o presente estudo compara estes grupos por categoria de município (capital, região metropolitana e interior), no período de março a junho de 2020, que corresponde aos quatro primeiros meses da pandemia no Brasil. Avaliam-se a magnitude e o sentido das diferenças de registros de óbitos entre os dois grupos. Foram utilizados gráficos e análise de regressão linear para comparações. Os achados indicam comportamento diferente de óbitos por mês de registro em comparação àqueles por mês de ocorrência entre março e junho. É importante identificar tal diferença de comportamentos dado que, para o monitoramento em curtíssimo prazo da pandemia, óbitos por data de registro antecipam óbitos cujo registro ainda será corretamente disponibilizado por data de ocorrência. Conclui-se que essa variação deve-

The Civil Registry provides information on demographic studies on mortality, fertility and nuptiality. Questions have been raised about death registration when the causes of death are related to Covid-19. Notification may be delayed. Based on information provided by the Civil Registry of deaths, stratified by two groups - date of registration and date of occurrence - by Covid-19, this study compares these groups by city categories (capital, metropolitan region, interior), over March, April, May and June 2020, occurring in the first four months of the pandemic in Brazil. The magnitude and meaning of the differences in death records between the two groups were assessed. Graphs and linear regression analyses were used for comparisons. The findings indicate a different behavior of deaths per month of registration compared to deaths per month of occurrence between March and June. It is important to identify such a difference in behavior since, for the very short-term monitoring of the pandemic, deaths from registry data anticipate deaths whose records will still be adequately available by occurrence data. Such variation occurs mainly due to the systematic correction and updating of the information. As for the city categories, the biggest difference between deaths by month of occurrence and registration was observed for the municipalities in the interior, in line with the spread of the epidemic towards the interior in the month of May.

El Registro Civil proporciona información sobre estudios demográficos en mortalidad, fecundidad y nupcialidad. Se han planteado preguntas sobre el registro de muertes cuando las causas de muerte son por covid-19, ya que la notificación puede producirse tarde. Con base en la información proporcionada por el Registro Civil de Defunciones, desglosada en dos grupos -fecha de inscripción y fecha de ocurrencia- por covid-19, este estudio los compara por tipo de municipio (capital, región metropolitana, interior), sobre los meses de marzo, abril, mayo y junio de 2020, corresponden a primeros cuatro meses de la pandemia en Brasil. Se evalúa la magnitud y el significado de las diferencias en los registros de defunción entre los dos grupos. Para las comparaciones se utilizaron gráficos y análisis de regresión lineal. Los hallazgos indican un comportamiento diferente de las muertes por mes de registro en comparación con las muertes por mes de ocurrencia entre marzo y junio. Es importante identificar tal diferencia en el comportamiento ya que, para el monitoreo a muy corto plazo de la pandemia, las muertes a partir de los datos del registro anticipan muertes cuyos registros aún estarán disponibles correctamente mediante los datos de ocurrencia. Se concluye que esta variación se produce principalmente por la corrección y actualización sistemática de la información. En cuanto al tipo de municipio, la mayor diferencia entre defunciones por mes de ocurrencia y de registro se registró para los municipios del interior, en línea con la propagación de la epidemia hacia el interior, en mayo.

Spanish Cardiac Catheterization and Coronary Intervention Registry. 29th Official Report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2019).

INTRODUCTION AND OBJECTIVES: The Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) presents its annual report on the activity for 2019. METHODS: All Spanish centers with a catheterization laboratory were invited to participate. Data were introduced online and analyzed by an external company together with the Steering Committee of the ACI-SEC. RESULTS: A total of 119 centers participated (83 public, 36 private). In all, there were 165124 diagnostic studies (4.7% more than in 2018). The use of pressure wire and intravascular ultrasound increased by 20% and that of optical coherence tomography by 8.4%. The number of percutaneous coronary interventions (PCI) rose by 4.5% (75 819 procedures). Of these, 22529 were performed in the acute myocardial infarction setting, with 91.8% being primary PCI (6.3% increase). The mean number of primary PCIs per million inhabitants increased to 439. Among PCIs, access was radial in 88.3%. There were 4281 transcatheter aortic valve implantations (21.0% increase), with an average of 90.9 per million inhabitants. Mitral valve repair also rose by 17.4% (n=385), left atrial appendage closure by 43.0% (n=921) and patent foramen ovale closure by 38.1% (n=710). CONCLUSIONS: In 2019, the use of intracoronary diagnostic techniques increased, as did that of diagnostic and therapeutic coronary procedures, mainly in primary PCI. Of particular note was the marked increase in the number of transcatheter aortic valve implantations, as well as in the number of mitral valve repairs and left atrial appendage and patent foramen ovale closure procedures.

[SARS-CoV-2 infection in patients on renal replacement therapy. Report of the COVID-19 Registry of the Spanish Society of Nephrology (SEN)]. / Situación de la infección por SARS-CoV-2 en pacientes en tratamiento renal sustitutivo. Informe del Registro COVID-19 de la Sociedad Española de Nefrología (SEN).

INTRODUCTION: The recent appearance of the SARS-CoV-2 coronavirus pandemic has had a significant impact on the general population. Patients on renal replacement therapy (RRT) have not been unaware of this situation and due to their characteristics they are especially vulnerable. We present the results of the analysis of the COVID-19 Registry of the Spanish Society of Nephrology. MATERIAL AND METHODS: The Registry began operating on March 18th, 2020. It collects epidemiological variables, contagion and diagnosis data, signs and symptoms, treatments and outcomes. It is an online registry. Patients were diagnosed with SARS-CoV-2 infection based on the results of the PCR of the virus, carried out both in patients who had manifested compatible symptoms or had suspicious signs, as well as in those who had undergone screening after some contact acquainted with another patient. RESULTS: As of April 11, the Registry had data on 868 patients, from all the Autonomous Communities. The most represented form of RRT is in-center hemodialysis (ICH) followed by transplant patients. Symptoms are similar to the general population. A very high percentage (85%) required hospital admission, 8% in intensive care units. The most used treatments were hydroxychloroquine, lopinavir-ritonavir, and steroids. Mortality is high and reaches 23%; deceased patients were more frequently on ICH, developed pneumonia more frequently, and received less frequently lopinavir-ritonavir and steroids. Age and pneumonia were independently associated with the risk of death. CONCLUSIONS: SARS-CoV-2 infection already affects a significant number of Spanish patients on RRT, mainly those on ICH, hospitalization rates are very high and mortality is high; age and the development of pneumonia are factors associated with mortality.
