Integrated Coronary Multicenter Imaging Registry - Extended

• Conditions: Coronary Artery Disease

• Registration Number: NCT04153903
• Lead Sponsor: Yonsei University

Brief Summary

The coronary images of invasive angiography and optical coherence tomography (or Coronary CT angiography) with FFR(Fractional Flow Reserve) values of the intermediate lesions (50-70% stenosis) will be prospectively registered.
