CAAS vFFR - angio-derived FFR measurement

CAAS vFFR is an angiographic method used to assess coronary physiology and calculate fractional flow reserve (FFR) values. The vFFR value indicates the significance of specific coronary lesions and shows where blood flow is limited. Furthermore, the 3D reconstruction enables the severity and percentage of stenosis to be assessed. Use of this novel method is supported by several clinical studies (e.g., FAST I; FAST Post) and shows promise as a replacement of the current gold standard, pressure wire invasive FFR measurement.¹
