This study compared virtual (residual) post‐PCI QFR and actual post‐PCI QFR from pre‐ and post‐stent angiograms in predicting post‐PCI FFR. While there was no difference in mean values, compared with post‐PCI FFR, the post‐PCI QFR correlated better than residual QFR. As the CFD algorithms improve, post‐PCI QFR can potentially serve as a quality control after PCI to reduce post‐PCI angina and adverse outcomes.
