Utility of Saline-Induced Resting Full-Cycle Ratio Compared with Resting Full-Cycle Ratio and Fractional Flow Reserve

Figure 4

(a) Correlations between the RFR and FFR and sRFR and FFR in the LCA. (b) Correlations between the RFR and FFR and sRFR and FFR in the RCA. Black color (), gray color (), and white color () show focal lesion, tandem lesion, and diffuse lesion, respectively. RFR, resting full-cycle ratio; FFR, fractional flow reserve; sRFR, saline-induced resting full-cycle ratio; LCA, left coronary artery; RCA, right coronary artery.
