Caption
Panel (a): A 74-year-old man had a moderate (60%) stenosis of proximal left anterior descending artery on CCTA, and invasive coronary angiography was subsequently performed and demonstrated a moderate stenosis (60%) by visual assessment. CT-derived fractional flow reserve (CT-FFR) and invasive fractional flow reserve (FFR) measured at 2 cm distal to the lesion were 0.92 and 0.89, respectively. Panel (b): A 61-year-old man had a mild (40%) stenosis of proximal right coronary artery on CCTA, and invasive coronary angiography demonstrated a diffuse severe stenosis (70%) by visual assessment in the proximal right coronary artery. CT-FFR and invasive FFR measured at 2 cm distal to the lesion were 0.59 and 0.64, respectively.
