A representative case of obstructive coronary artery disease with negative CT-FFR but a high global ΔCT-FFR. CT-FFR coronary computed tomography angiography−derived fractional flow reserve, ΔCT-FFR CT-FFR lesional gradient, LAD left anterior descending artery, LCX left circumflex artery, RCA right coronary artery. A 60-year-old man with a history of diabetes mellitus underwent a CCTA examination for suspected CAD. CCTA showed 30% stenosis (orange arrow) in the proximal and middle RCA, 70% stenosis in the proximal LAD and 30% stenosis in the proximal LCX. The CT-FFR value was 0.83, 0.80, and 0.83 for the RCA, LAD, and LCX systems, respectively. The corresponding ΔCT-FFR value was 0.17, 0.15, and 0.11, respectively. Thus, the global ΔCT-FFR was calculated as the sum of the ΔCT-FFR of 0.43
