Can we rely on iFR for avoiding FFR? Conclusions of a 5-year experience
Menezes, M. Nobre; Francisco, A. R. G.; Agostinho, J.; Ferreira, P. Carrilho; Jorge, C.; Torres, D.; Cardoso, P.; Oliveira, E. Infante deBackground: Recently, the instantaneous wave free ratio (iFR), has been proposed an alternative or complementary method to fractional flow reserve (FFR). This new method does not require the use of adenosine and may expedite the speed of functional assessment. The iFR “hybrid strategy” relies on values <0,86 or >0,93 as definitive results which would not require the use of FFR. However, this strategy is much le...
