Summary

The purpose of this study is therefore to show that associated with cardiac angiography echocardiography, in myocardial seen late, would provide the information necessary for the decision revascularization, in a timely manner. This would allow the patient to avoid duplication of tests including risk related to coronary angiography (bleeding complications, stroke ...) and those related to the implantation of coronary stent (stent) without expected earnings in case of non-viability . This would also reduce the length of hospital stay and costs due to numerous reviews.

Detailed description

Percutaneous coronary intervention is not recommended in stable patients with late presentation myocardial infarction, and myocardial viability needs to be evaluated before the procedure. The aim of the study is to evaluate the sensibility and specificity of dual-energy CT for the evaluation of myocardial viability in comparison to cardiac MRI. The experimental procedure is limited to a second CT acquisition performed 10 minutes in dual energy mode. Sensitivity and Specificity of delayed enhancement \>50% of myocardial thickness provided by dual-energy CT will be evaluated in comparison to cardiac MRI.

Conditions

• Myocardial Infarction

Interventions

Type	Name	Description
RADIATION	second propeller arm scanner	The experimental procedure is to conduct a second helical scanner strictly centered on the heart, 10 minutes after the first helix without inject contrast medium, to assess late enhancement.
