The objective of this study is to evaluate the precision of semi-automated lumen boundary identification from coronary computed tomography angiography (cCTA) by current version of HeartFlow software and the impact on fractional flow reserve (FFRCT), and to evaluate whether hemodynamic parameters affect plaque characteristics by using cCTA and optical coherence tomography (OCT).
Efficacy
To evaluate the concordance between cCTA minimal lumen area (MLA) and OCT MLA.
To evaluate the concordance between FFR value which derived cCTA and OCT.
To evaluate the relation between coronary plaque characteristics and hemodynamic parameters by OCT and cCTA.

Male and Female
Patients who underwent cCTA prior to coronary angiography and OCT within 6 months.
1. Prior coronary artery bypass graft (CABG) surgery
2. Contraindication to beta blocker agents or nitrates
3. Tachycardia or significant arrhythmia
4. Impaired chronic renal function (eGFR <30)
5. Subjects with known anaphylactic allergy to iodinated contrast material
6. Pregnancy or unknown pregnancy status in subject of childbearing potential
7. Cases with poor OCT or CCTA image for analyzing
