title: [Spanish registry of implantable cardioverter defibrillator. Second official report of the Spanish Society of Cardiology Working Group on Implantable Cardioverter Defibrillators (2005)].
abstract: OBJECTIVE
  We report the results for the Spanish Registry on Implantable Cardioverter Defibrillators (ICD) (year 2005), developed by the Working Group on ICD of the Spanish Society of Cardiology.
  
  
  METHODS
  Data were collected (prospectively in 77% of implants) by single page form questionnaires transmitted after the procedure to the Spanish Society of Cardiology. Participation was voluntary.
  
  
  RESULTS
  The number of implants sent to the Registry was 2050 and this represents 74.4% of the total ICDs implanted. The implantation rate per million was 46.5 and the estimated total implantation rate per million was 62.5. The proportion of first implants was 70.3%. The majority of patients were males, with a median age of 65 years, severe or moderate to severe left ventricular dysfunction and in functional class II or I. Ischemic heart disease was the more frequent underlying heart disease followed by dilated cardiomyopathy. The main reason for ICD indication was secondary prevention related to sustained monomorphic ventricular tachycardia or aborted sudden cardiac death. A significant number of prophylactic indications were done, specially in non ischemic heart disease. The proportion of ICD implanted at the electrophysiology laboratory by cardiac electrophysiologist continues increasing. There was an increase in the number of ICD plus cardiac resynchronization therapy, that represent a 23.6% of the implants. The incidence of complications during the implant was very low.
  
  
  CONCLUSIONS
  The National Registry on ICD, with a participation rate greater than in previous years, provides a representative sample of the ICD implants performed at our country.
