|Summary||Purpose: To clarify the relation between angiographic and functional severity under hybrid IFR-FFR strategy.
Method and Results: We analyzed 252 patients (340 lesions) undergoing CAG and IFR-FFR evaluation. Relation between IFR and % diameter stenosis (DS) were shown in Figure 1. Additional FFR was examined in 105 lesions with IFR values between 0.86 to 0.93. Figure 2 shows relation between additional FFR and %DS. After hybrid strategy, regular-mismatch was observed in 97 lesions (28.5%), whereas reverse-mismatch was seen in 51 lesions (15.0%). Lesion characteristics causing "visual-functional mismatch" are shown Table1.
Conclusion: Frequency of mismatch in hybrid strategy tended to be higher compared to previous studies between FFR and % DS. LAD and non-LAD with intermediate coronary artery stenosis had differing features between angiographic characteristics and hybrid IFR-FFR evaluation.
