NCT04549896

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Number of patients with successful CTO PCI procedure in both groups

    TIMI 3 flow restoration and residual stenosis \< 30%, by wire crossing in less than (≤) 60 minutes guidewire manipulation. TIMI flow and residual stenosis will be evaluated by a pool of 2 cardiologists not involved in the procedure and blinded regarding the randomized group.

    Immediately after surgery.

Secondary Outcomes (20)

  • Total time of CTO PCI procedure

    Immediately after surgery.

  • Rate of CTO PCI complications

    6 months starting from the date of the surgery.

  • Radiation level used during the CTO PCI procedure

    Immediately after surgery.

  • Volume of iodine contrast medium used for the CTO PCI procedure

    Immediately after surgery.

  • Cost of the the CTO PCI procedure

    Immediately after surgery.

  • +15 more secondary outcomes

Study Arms (2)

CT scan

EXPERIMENTAL

CT scan with a last generation 256 slice machine of occluded coronary artery before CTO PCI

Procedure: CT scan

Control

ACTIVE COMPARATOR

No CT scan before CTO PCI

Procedure: No CT scan

Interventions

CT scanPROCEDURE

Surgeon will perform a CT scan before the surgery procedure (CTO PCI) in order to increase the success rate of the surgery.

CT scan
No CT scanPROCEDURE

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.
