A 70-year-old female patient underwent to CCTA for chest pain. Right coronary artery (A) and left circumflex artery (D) were free from significant stenosis; whereas left anterior descending artery shows moderate proximal stenosis ((B), arrow). Ramus intermedius shows a severe, fibro-lipid plaque stenosis ((C), arrowhead). The FFR_CT assessment confirmed the functional significance of the stenosis proximal-ramus intermedius ((E), arrowhead), whereas the FFR_CT values of the left anterior descending artery were above the ischemia threshold of 0.80. The invasive coronary angiogram ((F), arrowhead) shows severe stenosis of the proximal tract of the ramus intermedius.
