Registro Español de Marcapasos. IX Informe Oficial de la Sección de Estimulación Cardiaca de la Sociedad Española de Cardiología (2011)

Introduction and objectives

To describe the results of the analysis of pacemaker implantations reported to the Spanish Pacemaker Registry in 2011, with particular reference to the population distribution and the selection of pacing modes.

Methods

Information provided by the European Pacemaker Patient Identification Card was processed using a purpose-built computer application.

Results

Data from 115 hospitals were analyzed, totaling 13 373 cards, representing an estimated 38% of implantations. The number of pacemaker generators and resynchronization devices implanted was 738 and 56.2 units per million population, respectively. The mean age of the patients who received a device was 76.7 years. Overall, 57.2% of first implantations and 56.5% of replacements were performed in men. Most implantations (38.7%) and generator replacements (41.9%) were performed in patients aged between 80 and 89 years. Of the pacemaker leads used, 99.7% were bipolar and 63% used an active fixation system. Overall, 20% of the patients with atrioventricular block or sick sinus syndrome were paced in VVI/R mode despite being in sinus rhythm.

Conclusions

With respect to previous years, the use of conventional pacemakers remained stable and the implantation of resynchronization devices has increased. The number of implantation procedures continues to be higher in men and in younger patients. Age and the degree of blockage remain as factors influencing the appropriate choice of pacing mode.Full English text available from: www.revespcardiol.org     

Análisis transversal de la resincronización cardiaca en España. Indicaciones,técnicas de implante,optimización y seguimiento

Introduction and objectives

A cross-sectional study of cardiac resynchronization therapy use in Spain was performed to analyze problems with indications, implantation, and patient follow-up.

Methods

Spanish cardiac resynchronization therapy implanter centers were identified, then the department members were surveyed and the data were recorded by each implantation team.

Results

Eighty-eight implanter centers were identified; of these, 85 (96.6%) answered the survey. A total of 2147 device implantations were reported, comprising 85.6% of the overall number of 2518 implantations estimated by the European Confederation of Medical Suppliers Associations for the same period. The reported implantation rate was 46 per million inhabitants versus an estimated implantation rate of 51 per million (European average, 131). Cardiac resynchronization therapy devices accounted for 84% of implantations, and upgrades to previously implanted devices, 16%. The majority of cardiac resynchronization therapy devices were implanted in men (70.7%). The mean age was 68 (12) years, and the mean left ventricular ejection fraction was 26.4% (5%). Most patients (67%) were in New York Heart Association functional class III. The group of patients for whom cardiac resynchronization therapy was indicated according to the latest update of the guidelines was significant: 17.3% among New York Heart Association class II patients and more than 21.6% among patients with atrial fibrillation. In all, electrophysiologists accounted for 73.8% of implanters, followed by surgeons, accounting for 21.4%.

Conclusions

The latest update of the guidelines is being progressively implemented in Spain, according to data obtained in patients in New York Heart Association class II or with atrial fibrillation. Nevertheless, the number of cardiac resynchronization therapy device implants is still well below the European average.Full English text available from:www.revespcardiol.org     

Registro Español de Desfibrilador Automático Implantable. XVI Informe Oficial de la Asociación del Ritmo Cardiaco de la Sociedad Española de Cardiología (2019)

Introduction and objectivesWe present the data corresponding to implantable cardioverter-defibrillator (ICD) implants in Spain in 2019.MethodsThe data were drawn from implant centers voluntarily completing a data collection sheet.ResultsIn 2019, 7003 implant sheets were received compared with the 7389 reported by Eucomed (European Confederation of Medical Suppliers Associations), indicating that data were collected from 94.8% of the devices implanted in Spain. Completion of the implant sheet ranged from 99.7% in the field “name of the implanting hospital” to 17.8% in the variable “reference hospital”. In 2019, 172 hospitals performed ICD implants and participated in the registry, a figure similar to that of 2018 (173). The total rate of registered implants was 149/million inhabitants; the rate reported by Eucomed was 157. Although this value represents the highest in the historical series, it is still much lower than the average rate of ICD implants in Europe (303).ConclusionsThe Spanish Implantable Cardioverter-Defibrillator Registry for 2019 reflects a growth in the number of ICD implants and is the year with the highest number of ICD implants in Spain. However, similar to previous years, the total number of implants in Spain is still much lower than the European Union average, with substantial differences between Spanish autonomous communities.Full English text available from:www.revespcardiol.org/en     

Registro Español de Desfibrilador Automático Implantable. IX Informe Oficial de la Sección de Electrofisiología y Arritmias de la Sociedad Española de Cardiología (2012)

Introduction and objectives

To summarize the findings of the Spanish Implantable Cardioverter-defibrillator Registry for 2012 compiled by the Electrophysiology and Arrhythmias Section of the Spanish Society of Cardiology.

Methods

Prospective data recorded voluntarily on single-page questionnaires were sent to the Spanish Society of Cardiology by each implantation team.

Results

Overall, 4216 device implantations were reported, representing 80.8% of the estimated total number of implantations. The reported implantation rate was 91.2 per million population and the estimated total implantation rate was 113 per million. The proportion of first implantations was 69.4%. We collected data from 161 hospitals (6 fewer than in 2011). The majority of implantable cardioverter-defibrillator recipients were men (83.4%). Mean age was 61.8 (13.4) years. Most patients had severe or moderate-to-severe ventricular dysfunction and were in New York Heart Association functional class II. Ischemic heart disease was the most frequent underlying cardiac condition, followed by dilated cardiomyopathy. The number of indications for primary prevention decreased over the previous year and now account for 58.1% of first implantations. Overall, 81% of the implantable cardioverter-defibrillator were implanted by cardiac electrophysiologists.

Conclusions

The 2012 Spanish Implantable Cardioverter-defibrillator Registry includes data on 80.8% of all implantable cardioverter-defibrillators implantations performed in Spain. This is the second consecutive year in which the number of implantations has slightly decreased compared to the previous year. This year, the percentage of implantations for primary prevention indications also decreased.Full English text available from:www.revespcardiol.org/en

Introduction and objectives

The Working Group on Cardiac Catheterization and Interventional Cardiology presents a yearly report on the data collected for the national registry. This information shows how procedures are distributed throughout Spain and makes comparisons with other countries feasible.

Methods

Institutions provided their data voluntarily (online) and were analyzed by the Working Group's Steering Committee.

Results

Data were provided by 108 hospitals (72 public and 36 private) that mainly treat adults, Covering 138 480 diagnostic procedures, 123 746 of which were coronary angiograms, slightly more than the year before, with a rate of 3008 coronary angiograms per million population. Percutaneous coronary interventions decreased slightly to 63 202 procedures with a rate of 1373 interventions per million population. Of the 94 701 stents implanted, 61% were drug-eluting stents. In the acute phase of myocardial infarction, 15 491 coronary interventions were performed, 9.4% more than in 2010, representing 24.6% of the total number of coronary interventions. The most frequent intervention for adult congenital heart disease was atrial septal defect closure (298 procedures). Percutaneous mitral valvuloplasty continued to decrease (286 procedures) and percutaneous aortic valve implantations increased, but at a slower pace than in the previous year, with 770 units implanted in 2011.

Conclusions

The greatest increase in activity has occurred in the field of myocardial infarction and percutaneous aortic valve implantation. The number of other procedures, both diagnostic and therapeutic, remained stable.Full English text available from: www.revespcardiol.org

Introduction and objectives

The Working Group on Cardiac Catheterization and Interventional Cardiology presents the yearly report on the data collected for the Spanish registry.

Methods

Institutions provided their data voluntarily (online) and the information was analyzed by the Working Group's Steering Committee.

Results

Data were provided by 109 hospitals (71 public and 38 private) that mainly treat adults. There were 136 912 diagnostic procedures, 120 441 of which were coronary angiograms, slightly fewer than the year before, with a rate of 2979 diagnostic studies per million population. Percutaneous coronary interventions increased slightly to 65 909 procedures, for a rate of 1434 interventions per million population. Of the 99 110 stents implanted, 62% were drug-eluting stents. In all, 17 125 coronary interventions were carried out during the acute phase of myocardial infarction, 10.5% more than in 2011, representing 25.9% of the total number of coronary interventions. The most frequently performed intervention for adult congenital heart disease was atrial septal defect closure (292 procedures). The use of percutaneous mitral valvuloplasty continued to decline (258 procedures) and percutaneous aortic valve implantations increased by only 10% in 2012.

Conclusions

In 2012, the only increase in hemodynamic activity occurred in the field of ST-elevation myocardial infarction, and the increasing trend had slowed for percutaneous aortic valve implantation and other procedures affecting structure.Full English text available from:www.revespcardiol.org/en     

Registro Español de Desfibrilador Automático Implantable. XVII Informe Oficial de la Asociación del Ritmo Cardiaco de la Sociedad Española de Cardiología (2020)

Introduction and objectivesWe present the data corresponding to implantable cardioverter-defibrillator (ICD) implants in Spain in 2020.MethodsThe data in this registry were drawn from implantation centers, which voluntarily completed a data collection sheet.ResultsIn 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.ConclusionsThe 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.Full English text available from:www.revespcardiol.org/en     

Registro Español de Ablación con Catéter. XI Informe Oficial de la Sección de Electrofisiología y Arritmias de la Sociedad Española de Cardiología (2011)

Introduction and objectives

The findings of the 2011 Spanish Catheter Ablation Registry are presented.

Methods

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

Results

Sixty-six Spanish centers voluntarily contributed data to the survey. Some 9662 ablation procedures were analyzed, averaging 146 (104) per center. The three main conditions treated were atrioventricular nodal reentrant tachycardia (n=2537; 26%), typical atrial flutter (n=2205; 23%) and accessory pathways (n=1813; 19%). Atrial fibrillation was the fourth most common substrate treated (n=1535; 16%) and showed a slight increase over figures for 2010. Ventricular arrhythmia ablation has increased considerably. The overall success rate was 94%; major complications occurred in 2.2% and overall mortality was 0.04%.

Conclusions

Data from the 2011 registry show a continued increase in the number of ablations performed with a generally high success rate and few complications. The use of complex substrate ablation continues to grow.     

Spanish Implantable Cardioverter-Defibrillator Registry. Eighth Official Report of the Spanish Society of Cardiology Working Group on Implantable Cardioverter-Defibrillators (2011)

Introduction and objectives

To summarize the findings of the Spanish Implantable Cardioverter-Defibrillator Registry for 2011 compiled by the Electrophysiology and Arrhythmia Section of the Spanish Society of Cardiology.

Methods

Each implantation team voluntarily and prospectively recorded data on a data collection form, which was then sent to the Spanish Society of Cardiology.

Results

Overall, 4481 device implantations were notified, representing 83.6% of the estimated total number of implantations. The notified implantation rate was 97 per million population and the estimated total implantation rate was 116.2 per million. First implantations accounted for 70.2% of the total notified. Data were collected from 167 hospitals (22 more than in 2010). Most implantable cardioverter-defibrillator implantations took place in men (82.1%). The mean age was 62.4 (14.1) years. Most patients had severe or moderate-to-severe ventricular dysfunction and were in New York Heart Association functional class II. The most frequent underlying cardiac condition was ischemic heart disease, followed by dilated cardiomyopathy. The number of indications for primary prevention increased over the previous year and accounted for 70.6% of first implantations. Overall, 78.4% of implantable cardioverter-defibrillators were implanted by cardiac electrophysiologists.

Conclusions

The 2011 Spanish Implantable Cardioverter-Defibrillator Registry includes data on almost 84% of all implantations of these devices performed in Spain. This was the first year in which the number of implants decreased slightly from the previous year, as also occurred in the rest of Europe. The percentage of implants for primary prevention continued to increase.     

Registro Español de Marcapasos. XVII Informe Oficial de la Sección de Estimulación Cardiaca de la Sociedad Española de Cardiología (2019)

Introduction and objectivesThis report describes Spanish cardiac pacing activity during 2019: quantities and types of devices and demographic and clinical factors.MethodsThe analysis is based on data obtained from the European Pacemaker Patient Identification Card, data submitted to the online platform cardiodispositivos.es, and supplier-reported data on the total number of implanted pacemakers.ResultsInformation was received on 15 833 procedures from 102 implantation centers, representing 39% of the estimated total activity. The implantation rates of conventional and resynchronization pacemakers were 832 and 32 units per million population, respectively. A total of 431 leadless pacemakers were implanted. Most implantations were performed in elderly patients (mean age, 78.7 years). Most electrodes were bipolar and with active fixation and 34.1% were magnetic resonance imaging-compatible. Atrioventricular block was the most common electrocardiographic abnormality. Dual-chamber sequential pacing predominated; nonetheless, up to 20% of patients in sinus rhythm received a single-chamber ventricular pacemaker, mainly those older than 80 years of age and women. Remote monitoring capability was present in 41% of cardiac resynchronization therapy pacemakers and in 14.8% of conventional pacemakers.ConclusionsConsumption of pacing generators increased by 1.6%, mainly due to a 15.1% increase in cardiac resynchronization therapy pacemakers. Sequential pacing predominates; its use is influenced by age and sex. Remote monitoring increased by 20.6% in cardiac resynchronization therapy pacemakers and continues to be scarce in conventional pacemakers.

Introduction and objectivesThis 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.MethodsInformation consisted of the European Pacemaker Patient Card, data submitted to the cardiodispositivos.es online platform, the databases of participating centers, and supplier-reported data.ResultsA 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.ConclusionsIn 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.Full English text available from:www.revespcardiol.org/en     

Registro Español de Marcapasos. XVI Informe Oficial de la Sección de Estimulación Cardiaca de la Sociedad Española de Cardiología (2018)

Introduction and objectivesThis report describes the result of the analysis of the implanted pacemakers reported to the Spanish Pacemaker Registry in 2018.MethodsThe analysis is based on the information provided by the European Pacemaker Identification Card and supplier-reported data on the overall number of implanted pacemakers.ResultsInformation was received from 90 hospitals, with a total of 12 148 cards, representing 31% of the estimated activity. Use of conventional and resynchronization pacemakers was 825 and 77 units per million people, respectively. The mean age of the patients receiving an implant was 78.3 years, and 54% of the devices were implanted in people aged > 80 years. A total of 77.1% were first implants and 21.6% corresponded to generator exchanges. Bicameral sequential pacing was the most frequent pacing mode but was less frequently used in patients aged > 80 years and in women. Single chamber VVI/R pacing was used in 28% of patients with sick sinus syndrome and in 24.7% of those with atrioventricular block, despite being in sinus rhythm.ConclusionsThe total consumption of pacemaker generators in Spain increased by 1.2% compared with 2017, mainly due to an 8.7% increase in cardiac resynchronization therapy with pacemaker generators. Selection of pacing mode was directly influenced by age and sex.     

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

Introduction and objectivesThis article presents the data corresponding to implantable cardioverter-defibrillator (ICD) implantations in Spain in 2021.MethodsThe data were drawn from implanting centers, which voluntarily completed a data collection sheet during the procedure.ResultsIn 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.ConclusionsThe 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.
