Spanish Pacemaker Registry. 16th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2018).

INTRODUCTION AND OBJECTIVES: This report describes the result of the analysis of the implanted pacemakers reported to the Spanish Pacemaker Registry in 2018. METHODS: The analysis is based on the information provided by the European Pacemaker Identification Card and supplier-reported data on the overall number of implanted pacemakers. RESULTS: Information 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. CONCLUSIONS: The 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.

Spanish Pacemaker Registry. 15th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2017).

INTRODUCTION AND OBJECTIVES: This report describes the data reported to the Spanish Pacemaker Registry concerning the activity in cardiac pacing in 2017 in Spain. METHODS: The analysis is based on the data obtained from the European Pacemaker Identification Card and the information reported by supplier companies related to global number of implanted pacemakers. RESULTS: Information was received from 106 hospitals, with a total of 12672 cards, representing the 32.1% of the total pacing activity. Conventional pacemaker and resynchronization pacemaker rate was 820 units/million and 26 units/million inhabitants respectively. A total of 333 leadless pacemakers were implanted. The mean age was 77.9 years, predominantly men (58.5%). Most electrodes were bipolar, with active fixation and only 20% had magnetic resonance protection. Atrioventricular block was the most common electrocardiographic disturb. Most patients received bicameral sequential pacing although single chamber VVIR pacing was used in up to 21.8% of patients. Patients older than 80 years benefited less from physiological pacing and resynchronization therapy. CONCLUSIONS: Total use of pacemaker generators remains stable with respect to 2016. Age is the main factor that influences pacing mode selection, which could be improved in around 22% of patients. Leadless pacing continues to rise.

Spanish Pacemaker Registry. 14th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2016).

INTRODUCTION AND OBJECTIVES: This report describes the results of analysis of implanted pacemakers reported to the Spanish Pacemaker Registry. METHODS: The analysis was based on information provided by the European Pacemaker Identification Card. RESULTS: Information was received from 115 hospitals, with a total of 12 697 cards, representing 32.3% of the estimated activity. Use of conventional and resynchronization pacemakers was 818 and 79 units per million inhabitants, respectively. A total of 200 leadless pacemakers were implanted. The mean age of the patients receiving an implant was 77.8 years, and 52% of devices were implanted in persons older than 80 years. In all, 74.9% were first implants and 23.4% corresponded to generator exchange. Endocardial leads were bipolar, 82.9% with active fixation, and 16.1% had magnetic resonance imaging protection. Most patients received bicameral sequential pacing, although single chamber pacing VVI(R) was used in 26.7% of the patients with sick sinus syndrome and in 23.8% of those with atrioventricular block, despite sinus rhythm. CONCLUSIONS: Total use of pacemaker generators in Spain has increased by 1.6% compared with 2015. Most implanted leads have active fixation and less than 20% have magnetic resonance imaging protection. Age and sex directly influenced pacing mode selection, which could be improved in around 32% of patients.

Spanish Pacemaker Registry. Thirteenth Official Report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2015).

INTRODUCTION AND OBJECTIVES: We describe the results of the analysis of the devices implanted and conveyed to the Spanish Pacemaker Registry in 2015. METHODS: The report is based on the processing of information provided by the European Pacemaker Patient Identification Card. RESULTS: We received information from 111 hospitals, with a total of 12 555 cards, representing 32.1% of all the estimated activity. The use of conventional generators and resynchronization devices was 820 and 73 units per million population, respectively. The mean age of the patients receiving an implantation was 77.7 years, and more than 50% of the devices were implanted in patients over 80 years of age. Overall, 58.6% of the implants and 58.8% of the replacements were performed in men. All of the endocardial leads employed were bipolar, 81.5% had an active fixation system, and 16.5% were compatible with magnetic resonance. Although dual chamber sequential pacing continues to be more widespread, pacing with VVI/R mode is used because up to 23.8% of the patients with sinus node disease are in sinus rhythm, as are 24.1% of those with atrioventricular block. CONCLUSIONS: The total use of pacemaker generators in Spain has increased by about 5% with respect to 2014. The majority of the leads implanted are of active fixation, and less than 20% are protected from magnetic resonance. The factors directly related to the selection of pacing mode are age and sex. In around 20% of patients, the choice of the pacing mode could be improved.
