title: [Spanish Implantable Cardioverter-Defibrillator Registry. Third Official Report of the Spanish Society of Cardiology Working Group on Implantable Cardioverter-Defibrillators (2006)].
abstract: OBJECTIVE
  To report the 2006 findings of the Spanish Implantable Cardioverter-Defibrillator (ICD) Registry, established by the Working Group on Implantable Cardioverter-Defibrillators, Electrophysiology and Arrhythmia Section, Spanish Society of Cardiology.
  
  
  METHODS
  Each ICD team voluntarily reported data to the Spanish Society of Cardiology by completing a single-page questionnaire. Prospective data were collected on 91.8% of implantations.
  
  
  RESULTS
  In total, 2679 implantations were reported to the registry (86.6% of the estimated total). The reported implantation rate was 60 per million inhabitants, and the estimated rate was 69 per million. The proportion of first implantations was 80%. The majority of ICDs were implanted in males (mean age 61.5 [14] years) with severe or moderate-to-severe left ventricular dysfunction who were in functional class II or I. Ischemic heart disease was the most frequent etiology, followed by dilated cardiomyopathy. This is the first year that half of first device implantations were carried out for primary prevention, with substantial increases among patients with ischemic heart disease and dilated cardiomyopathy. The number of ICDs incorporating cardiac resynchronization therapy has continued to grow, and now comprises 28.6% of all devices implanted. As in the previous year, around 70% of ICD implantations were performed in an electrophysiology laboratory by a cardiac electrophysiologist. The incidence of complications during device implantation was very low.
  
  
  CONCLUSIONS
  The 2006 Spanish Implantable Cardioverter-Defibrillator Registry contains data on more than 86% of all ICD implantations performed in Spain. Half of first device implantations were carried out for the purposes of primary prevention.
