Conditions
Summary
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.

Interventions
Surgeon will perform a CT scan before the surgery procedure (CTO PCI) in order to increase the success rate of the surgery.
The surgery procedure (CTO PCI) will be performed following the standard of care, meaning that the surgeon will not perform a CT scan before the surgery procedure.
