Spanish Implantable Cardioverter-defibrillator Registry. Tenth Official Report of the Spanish Society of Cardiology Electrophysiology and Arrhythmias Section (2013).

INTRODUCTION AND OBJECTIVES To present the findings of the Spanish Implantable Cardioverter-defibrillator Registry for 2013 compiled by the Electrophysiology and Arrhythmias Section of the Spanish Society of Cardiology. METHODS Prospective data were voluntarily recorded on a data collection form and sent to the Spanish Society of Cardiology by each implantation team. RESULTS Overall, 4772 device implantations were reported, representing 85% of the estimated total number of implantations. The reported implantation rate was 102 per million population and the estimated total implantation rate was 120 per million. The proportion of first implantations was 68.8%. Data were received from 154 hospitals (4 fewer than in 2012). Most implantable cardioverter-defibrillator recipients were men (83.3%). The mean age was 62.5 (13.4) 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. Indications for primary prevention accounted for 53.0% of first implantations, consolidating the decrease first observed in 2012. Overall, 79.8% of devices were implanted by cardiac electrophysiologists. CONCLUSIONS The 2013 Spanish Implantable Cardioverter-defibrillator Registry includes information on 85% of the devices implanted in Spain. The total number of implantations increased compared with the previous 2 years. The percentage of implantations for primary prevention indications decreased compared with the previous year.
