Coronary artery findings in FFR-CT, invasive FFR, and post percutaneous coronary intervention for the LMCA. (A) Fractional flow reserve from computed tomography (FFR-CT) showed hemodynamically significant stenosis in the left main coronary artery (LMCA). (B) The invasive fractional flow reserve (FFR) value decreased to 0.57 at distal site of the LMCA. (C) Invasive coronary angiography after deployment of a drug-eluting stent in the LMCA-LAD.
