The first published study has validated renal FFR (rFFR) as a dynamic assessment of renal functional stenosis under hyperemic conditions.
As a pressure-derived index, the merits of rFFR are as follows: (1) it is lesion-specific to provide a measure of the reduction in renal blood flow caused by the stenosis; (2) it takes into account of the collateral flow, which can render an anatomical blockage without functional significance; (3) a morphological severe stenosis may not induce a significant TSPG, if the artery has slow flow due to renal parenchymal impairment, which, in contrast, adds to the feasibility of assessing the severity of RAS diagnosed by rFFR; (4) besides, Colyer et al .
