Within this context, Xu I et al i .[9] provide new data from the FAVOR III China trial, which sought to determine whether the peri-procedural use of quantitative flow ratio (QFR) to guide lesion selection for percutaneous coronary intervention (PCI) might improve clinical outcomes, compared with angiography-guidance alone. Accordingly, a greater proportion of lesions with QFR <= 0.80 was treated in the QFR-guided group than in the angiography-guided group [1990 (96.7%) of 2058 lesions vs. 1843 (91.1%) of 2023 lesions].
