The main objective of this study is to determine among the patients included a subpopulation that does not need a defibrillator.

This will be done by comparing the number of discordant segments (mismatch) between patients who have a severe arrhythmia (ventricular tachycardia or ventricular fibrillation) with appropriate electrical therapy within 3 years of monitoring and others. "Mismatch" in the definition of this objective is the usual definition: score 3.4 in I123-MIBG (Iodine 123 metaiodobenzylguanidine) and PET at 0,1,2.

Condition Intervention
Defibrillators, Implantable

Official Title: PET / CT With 18F-FDG (18F-fluorodeoxyglucose Positron Emission Tomography/Computed Tomography): Does it Optimize the I 123-MIBG (Iodine 123 Metaiodobenzylguanidine) Imaging Results in the Search for Discriminating Factors for the Implementation of an Implantable Defibrillator for Primary Prevention in Patients With Heart Failure of Ischemic Origin?

Primary Outcome Measures:
  • Presence/absence of a triggering of the defibrillator within 3 years of follow up [ Time Frame: 3 years ]
    The primary endpoint is the triggering of the defibrillator within 3 years of follow up. Mismatch segments will be studied as predictors of arrhythmia.

Enrollment: 6
Study Start Date: June 2011
Study Completion Date: June 2016
Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
The study population
See inclusion and exclusion criteria.
Other: Addional imaging
All patients will systematically have an 18F-FDG PET-CT (18F-fluorodeoxyglucose positron emission tomography/computed tomography) and a 123MIBG (Iodine 123 metaiodobenzylguanidine) scintigraphy


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Coronary patients that should benefit from ICD (Implanted Cardiac Defibrillator) implantation for primary prevention according to current recommendations, that is to say with LVEF (left ventricular ejection fraction) <30% in NYHA (New York Heart Association) stage II or III and within one month of an myocardial infarction or within 3 months of a complete revascularization.

Inclusion Criteria:

  • Patient with ischemic heart disease with heart failure
  • Patients who received myocardial perfusion scintigraphy
  • Indication for the implantation of an ICD installed according to current recommendations : LVEF <30% and NYHA (New York Heart Association) stage II, III.
  • The subject must have given his informed consent and signed consent
  • The subject must be a member or beneficiary of a social security system

Exclusion Criteria:

  • Pregnant or lactating women
  • History of "open heart" cardiovascular surgery
  • Inability to sign informed consent (patient under guardianship)
  • Patients with diabetes mellitus
  • Patient with proven dementia
  • Person refusing to sign the consent
  • Someone who already has an ICD at baseline
  • Life expectancy less than one year (NYHA IV, other diseases such as neoplastic disease in an advanced stage)
