NCT02323503

Brief Summary

Cardiac resynchronization therapy (CRT) has been shown to reduce heart failure (HF), hospitalizations and death in patients with left ventricular ejection fraction (LVEF) \<35% and wide QRS. CRT provides electromechanical resynchronization and improves LV systolic function. The induced LV reverse remodeling or near normalization in LVEF to ≥45% is associated with a significant reduction in the risk of subsequent life-threatening ventricular tachyarrhythmias (VTA). And at the time of replacement, the need for defibrillator back-up after an event-free first CRT-D service-life for patients with improved LVEF is a controversy question. 80% of Implantable Cardioverter Defibrillator (ICD) patients implanted for primary prevention do not experience VTA during the life-time of their first device. So, regarding patients implanted with a CRT-D for primary prevention at the time of first implantation, the question is will they experience VTA after their device replacement by another CRT-D.

Study Population

Patients initially implanted with a CRT-D (cardiac resynchronization therapy with defibrillator) device for primary prevention indication for defibrillation, requiring a device replacement by another CRT-D because of battery depletion

You may qualify if:

  • Patient with primary prevention indication for defibrillation at the time of the first CRT-D implantation
  • Patient implanted as first replacement by a CRT-D device (CRT-D by CRT-D)
  • Lifetime of the previous CRT-D \> 3 years
  • Patient willing and able to comply with the protocol and who has provided written informed consent
  • Patient whose medical situation is stable.

You may not qualify if:

  • Patient with an ICD lead under advisory (e.g. Fidelis lead)
  • Right or left ventricular leads exchange during CRT-D replacement
  • Non functional atrial (except for patient with chronic AF) or right/left ventricular leads
  • Life expectancy \< 1 year
  • Age \< 18 years
  • Pregnant woman or woman who plan to become pregnant during the trial
  • Participation in another interventional clinical study
