Key Points Pressure‐bound (pb) coronary flow reserve (CFR) is a novel estimation of CFR, calculated from easily obtained baseline and hyperemic pressure assessment Validation of pb‐CFR in previously reported lesions showed accuracy of 84% to CFR with sensitivity of 96% and specificity of 60% FFR >0.75 and low pb‐CFR in DEFER was associated with increased angina and complications compared to high pb‐CFR and this risk was not modified by elective revascularization.
