Figure 1 - Images A to D refers to a Right Coronary Artery (RCA) vessel and lesion assessment by Quantitative Flow Ration (QFR). Images E to H presents a Left anterior descending artery (LAD) vessel with lesion analysis using Cardiovascular Angiographic Analysis Systems for vessel Fractional Flow Reserve (CAAS-vFFR). Two orthogonal angiographic projections’ quantitative coronary analysis of the RCA (A and B); QFR analysis over the 3-dimensional (3D) reconstruction of the RCA (C); QFR graphs showing the lesion’s proximal and distal reference vessel diameter and the narrowest point of the lesion (D). CAAS-vFFR analysis showing LAD orthogonal angiographic projections (E and F); CAAS-vFFR analysis over LAD’s 3D reconstruction (G); CAAS-vFFR analysis graphs presenting the whole vessel diameter marking the lesion’s proximal and distal reference vessel diameter followed by the narrowest point within the lesion (H). “p” = proximal; “d” = distal.
