Spanish Catheter Ablation Registry. 11th Official Report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (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 Catheter Ablation Registry. Fifth official report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2005)

INTRODUCTION AND OBJECTIVES: The findings (i.e., success and complication rates) of the 2005 Spanish Catheter Ablation Registry, as prepared by the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias, are presented. METHODS: As in previous years, data were collected in two ways: retrospectively using a standardized questionnaire sent to electrophysiology laboratories by the Working Group on Electrophysiology and Arrhythmias, and prospectively from a central database. Each participating center selected its own preferred method of data collection. RESULTS: Forty-seven centers contributed data to the registry. A total of 6162 ablation procedures were analyzed, averaging 131 (88) per center. As in previous reports, the three main conditions treated were atrioventricular nodal reentrant tachycardia (n=1795, 29%), accessory pathways (n=1591, 26%), and typical atrial flutter (n=1378, 22%). Atrial fibrillation was the fourth most common condition treated (n=480, 8%). The overall success rate was 93%, major complications occurred in 1.05%, and the mortality rate was 0.03%. CONCLUSIONS: With more than 6000 ablation procedures recorded and with the participation of a greater number of centers throughout the country, the Spanish Catheter Ablation Registry is becoming increasingly representative and is consolidating its value as a point of reference. The number of catheter ablations carried out for atrial fibrillation in Spain is continuing to grow.     

Spanish catheter ablation registry. 10th official report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2010)

Introduction and objectives

The findings of the 2010 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

Fifty-seven Spanish centers voluntarily contributed data to the survey. A total of 8762 ablation procedures was analyzed, averaging 154 (97) per center. The 3 main conditions treated were atrioventricular nodal reentrant tachycardia (n=2321; 27%), typical atrial flutter (n=1839; 22%), and accessory pathways (n=1738; 20%). Atrial fibrillation was the fourth most common condition treated (n=1309; 15%), and reflects mild growth. The overall success rate was 94%, major complications occurred in 1.7%, and the overall mortality rate was 0.06%.

Conclusions

Data from the 2010 registry show that the number of ablations carried out continued to increase and exceeded 8700 ablations for the second time. In addition, they show, in general, a higher success rate and a lower number of complications. Again, cavotricuspid isthmus ablation for typical atrial flutter was the second most common condition treated. The number of catheter ablations carried out for ventricular arrhythmias in Spain is growing compared to the previous year.Full English text available from:www.revespcardiol.org     

Spanish Heart Transplant Registry. 29th Official Report of the Spanish Society of Cardiology Working Group on Heart Failure

Introduction and objectives

The present report updates the characteristics and results of heart transplantation in Spain, mainly focused in the 2008-2017 period.

Spanish Registry on Catheter Ablation. Second official report of the Working Group on Electrophysiology and Arrhythmias of the Spanish Society of Cardiology (2002)

INTRODUCTION AND OBJECTIVES: We present the results (success rates and complication rates) for the second consecutive year of the 2002-Spanish Catheter Ablation Registry, developed by the Spanish Society of Cardiology. MATERIAL AND METHOD: Data were collected retrospectively by questionnaires sent to all interventional cardiology laboratories in Spain. The outcomes and complications of ablation procedures performed during 2002 were classified according to the substrate or mechanism of arrhythmia treated. RESULTS: Forty-three centers voluntarily submitted completed questionnaires. The number of procedures analyzed was 4970, performed at 42 centers, for a mean of 118 78 procedures per center. Global outcome rates were success in 93%, major complications in 1.2%, and death in 0.04% of the patients. The three main substrates treated were AV nodal reentry (29%), accessory pathways (28%) and common atrial flutter (24%). CONCLUSIONS: The 2002 Spanish National Catheter Ablation Registry reports the activity of the majority (90%) of interventional cardiology laboratories in Spain. The efficacy of catheter ablation procedures in Spain is high, and the complication and mortality rates are low.     

Spanish Heart Transplantation Registry. 16th official report of the Spanish Society of Cardiology Working Group on Heart Failure, Heart Transplantation, and Associated Therapies

This paper describes the general situation regarding heart transplantation in Spain and the results obtained using the technique, incorporating data for the year 2004. In 2004, 294 heart transplants were carried out, which brings the total number of procedures performed since 1984 to 4680. Clinically, the typical heart transplant recipient in Spain is male, aged around 50 years, has blood group A, has non-revascularizable coronary artery disease, and is in NYHA functional class IV/IV. The percentage of emergency heart transplantations was 35%, which is higher than in the previous year (29%), and higher than the mean for the preceding 5 years (22%). The early mortality rate was 10%, which is lower that the mean for the preceding 5 years (13%). After combining the results for 2004 with those of previous years, the probability of survival at 1, 5 and 10 years was 80%, 70% and 60%, respectively. When the survival rates for different time periods were analyzed, a significant improvement could be seen in the last 5 years, with recent survival rates being 85% and 72% at 1 and 5 years, respectively. The most frequent cause of death in the first month was acute graft failure; in the first year, infection and rejection; and, over the long term, tumors and a combination of graft vasculopathy and sudden death. A comparative analysis of survival rates showed that long-term results in Spain are slightly better than those published in the world literature. Moreover, survival has tended to improve gradually in recent years.     

Spanish Cardiac Catheterization and Coronary Intervention Registry. 16th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2006)

This article summarizes the data reported to the 2006 registry of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology. Data were obtained from 135 centers. Of these, 125 performed catheterizations mainly in adults, while 10 carried out procedures in pediatric patients only. In 2006, 126,196 diagnostic catheterizations were carried out. Of these, 113,228 were coronary angiograms, 7.6% more than in 2005. The population-adjusted rate was 2560 coronary angiograms per million inhabitants. A total of 57,041 percutaneous coronary interventions were performed, which was 7.8% more than in the previous year and which corresponds to a rate of 1293 per million inhabitants. Stents were used in 96.1% of coronary interventions. Overall, 90,006 stents were implanted, of which 59.3% were drug-eluting stents. Moreover, 10,067 interventions were carried out for acute myocardial infarction, 20.6% more than in 2005 and accounting for 17.6% of all percutaneous coronary interventions. Non-coronary interventions were most frequently performed for adult congenital heart disease, with closure of an atrial septal defect being the most numerous, at 334 procedures. Percutaneous mitral valvuloplasties were performed in 431 cases, a similar figure to that recorded in the previous registry, and the success rate was 93.6%. Each year, radial access continues to be used more frequently for coronary procedures. Finally, it is important to emphasize that a high percentage of laboratories reported results, which ensures that the data presented here can serve as an international reference source for percutaneous cardiac interventions performed in Spain.     

Spanish Registry of Cardiac Catheterization and Coronary Interventions. Thirteenth Official Report of the Working Group on Cardiac Catheterization and Interventional Cardiology of the Spanish Society of Cardiology (1990-2003)

The results of the Registry of the Working Group on Cardiac Catheterization and Interventional Cardiology of the Spanish Society of Cardiology for 2003 are presented. Data were obtained from 112 centers representing nearly all cardiac catheterization laboratories in Spain; 104 centers performed mainly adult catheterization and 8 carried out pediatric procedures only. In 2003, 105,939 diagnostic catheterization procedures were performed, including 90 939 coronary angiograms, representing a total increase of 8.5% in comparison to 2002. The population-adjusted rate was 2171 coronary angiograms per 106 inhabitants. Coronary interventions increased by 14.4% in comparison to 2002, with a total of 40,584 procedures and a rate of coronary interventions of 969 per 106 inhabitants. Coronary stents were used in 92.5% of the procedures (47,249 units implanted, for a total increase of 22% in comparison to 2002). About one fifth (20.2%) of the implanted stents were drug-eluting stents (11,699 units). A total of 6080 percutaneous coronary interventions were done in patients with acute myocardial infarction, representing an increase of 27.5% in comparison to 2002, and accounting for 14.9% of all interventional procedures. Of the noncoronary interventions recorded, we note the increase in percutaneous mitral valvuloplasties (21.6%) and atrial septal defect closures (86%), and also the increase in pediatric interventions (13.3%). In conclusion, we emphasize the high rate of reporting by laboratories, which allows the Registry to compile data that are highly representative of the activity at cardiac catheterization laboratories in Spain.     

Spanish Registry of Pacemakers. Second Official Report of the Working Group on Cardiac Stimulation of the Spanish Society of Cardiology (1994-2003)

This report describes the data of the Spanish Registry of Pacemakers, based on the European Pacemaker Identification Card, and the changes in the use of different stimulation modes since 1994. Of note is the significant and steady change towards more physiological modes of stimulation (which maintain atrioventricular synchrony). These modes accounted in 2003 for 69.9% among patients with sick sinus syndrome and 67.7% among patients with atrioventricular block. In the population less than 80 years of age these percentages were 78% for sick sinus syndrome and 78.7% for atrioventricular block. The vast majority of electrodes implanted for stimulation were bipolar.     

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.
