Gedetailleerde beschrijving
The hypothesis of the study is the superiority of the interventional management over medical therapy alone in preventing the occurrence of the primary endpoint of the study assessed 1 year after randomization.
Objectives: To demonstrate the superiority of the interventional management on top of optimal medical therapy over optimal medical therapy alone in preventing the occurrence of the primary endpoint of the study assessed 1 year after randomization
Design : Multicenter, prospective randomized 1 :1, open-label blinded endpoint study
Target population : Heart transplant recipients, aged ≥18 years, without coronary artery disease-related symptoms, with angiographically significant coronary artery stenoses (≥50% anatomically adequate for a revascularization by coronary angioplasty with stent implantation, with no contraindication to dual antiplatelet therapy associating aspirin and a P2Y12 inhibitorfor a duration of 12 monthsand with ni grade IA ACC/AHA indication for revascularization
Inclusion period: 12 months (may be extended based on the inclusion rythme)
Maximum duration of participation for patients : 13 months
Total duration of the study : 37 months
Primary endpoint : The composit of death, myocardial infarction, retransplantation, implantation of transitory or definitve ventricular assist devices, new or worsening heart failure, graft failure and/or a decrease of left ventricular ejection fraction of at least 25% compared to baseline.The occurrence of any event qualifying for the primary endpoint will be assessed by a Cox survival analysis stratified on center.The primary endpoint will be assessed 12 months after randomization.
Secondary endpoints : Any of the individual events defining the primary outcome at 1 year
Number of patients to be included and power calculation : 80 patients per group. A 1 year primary endpoint rate of 30% in the active and 50% in with an inclusion period of 24 months and alpha=5% warants a 90% power using a cox model.

Beschrijving
Inclusion Criteria:
- Patients ≥ 18 years old
