Integrated Coronary Multicenter Imaging Registry - Extended

November 3, 2019 updated by: Yonsei University
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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Patients with intermediate lesions
Imaging cohort will be performed invasive angiography and optical coherence tomography (or Coronary CT angiography) with FFR(Fractional Flow Reserve) values of the intermediate lesions (50-70% stenosis)
Other: OCT, coronary angiography, FFR
Coronary images by OCT and angiography and FFR values will be registered.
