Figure 2 iFR® cut-off value and fractional flow reserve-measurement: An iFR®-value of ≤ 0.
89 indicates a hemodynamically significant stenosis (above, red bars), whereas an iFR®-value of ≥ 0.90 indicates no need for an intervention (green bar). Accordingly, FFR-indices of ≤ 0.80 lead to a revascularization, whereas FFR-indices of > 0.80 indicate a non-significant coronary stenosis. iFR®: Instantaneous wave-free ratio; FFR: Fractional flow reserve.
