The chronic total occlusion of a coronary artery is the most frequent cardiac disease in the developped countries. The percutaneous coronary intervention is one of the existing treatments. This procedure is long, expensive and uses a lot of contrast medium and X ray. With this study, the investigators want to adress the impact of CT scan performed before the surgical procedure. A better knowledge of the patient's anatomy could lead to a better success rate of the operation, with a lower radiation, lower contrast injection, and a faster and more cost-efficient procedure.
