Error in angiography‐derived FFR. (A) An anatomically severe circumflex case. In this case, the method applied an assumed value for microvascular resistance based on a population average, which resulted in considerable disagreement between angiography‐derived and invasive FFR (0.55 vs 0.82). (B) Bland–Altman plot from a meta‐analysis of 13 studies (1842 vessels). There is minimal bias (gray line), but the ±95% limits of agreement were FFR ±0.14. FFR indicates fractional flow reserve.
