Assessment
Primary outcomes Evaluation of the difference and correlation between predictive value of iFR, RFR and dPR; average predictive value and post PCI value of iFR, RFR and dPR
Key secondary outcomes 1) Evaluate separately by Type A, B, C (tandem lesion, diffuse lesion)
2) Comparison of measurement time of RFR and dPR compared to iFR
3) Drift of each pressure wire
4) Proportion of 0.9 or more for post iFR, post RFR and post dPR; whether additional treatment was done
5) Whether post FFR achieves 0.8 or more. Whether additional treatment was done
6) Evaluation of plaque properties with IVUS (Terumo,Boston,NIPRO) of fiber component, lipid component, calcification. In particular, the predictive value when highly calcified at least 270 degrees of calcification is observed is not significantly different from the post PCI value.
7) Number of stents used and stent length
