Background: An ageing population and the extension of indications will in all probability result in an increasing number of cardiac device implantations. Methods: Patients implanted in 2008 and 2009 were identified by means of the French National Hospital Discharge database to establish the implantation rate and the National Health Insurance (NHI) Information System database for patient profiles (76% of the population). Results: Of the 64,306 pacemaker implantations (1003.7 per million inhabitants [pmi]) in 2009, 21.4% were single chamber, 75.4% double chamber and 3.2% triple chamber (CRT-P). Of the 9028 cardioverter-defibrillator implantations (140.8 pmi) in 2009, 30.1% were single chamber, 27.5% double chamber and 42.5% triple chamber (CRT-D), accounting for 65% of cardiac resynchronization therapy (CRT) implants. Among NHI beneficiaries, 58.6% of cardioverter-defibrillators were implanted for primary prevention. Between 2008 and 2009, CRT-P implantations increased by 8.8% and CRT-D implantations by 29.3%. Regional variations in implantation rates were observed regarding single-chamber pacemakers (15-33%) and CRT-D among CRT (46.2-73.8%). Pacemaker implantations cost 158.4 million overall, 4.5% of which was for CRT-P; cardioverter-defibrillator implantations cost 96 million, 49% of which was for CRT-D. For NHI beneficiaries, 11.9% of CRT-P patients and 6.5% of CRT-D patients already had a device of the same type implanted in the 3 preceding years. Conclusion: The results confirm the increase in cardioverter-defibrillator implantations in France. The implantation rate remains lower than that in the USA but falls within the European average. Reasons behind significant regional variations in implantation rates need further study. (R.A.)
