Fractional Flow Reserve (FFR) is an important indicator for the hemodynamic significance of a coronary stenosis [1]. The FFR is defined as the pressure drop over the stenosis under hyperemia. The pressure drop, and thus the FFR, depends on both the geometry and flow. In clinical practice, the FFR is measured with a pressure wire under administration of adenosine and intervention is warranted if the FFR is below 0.8.
