摘      要：Objective Quantitative flow ratio (QFR) is a novel approach to derive FFR from diagnostic coronary angiography. The FAVORⅡChina Study demonstrated excellent accuracy of online QFR in identifyinghemodynamicallysignificantcoronarystenosisin the catheterization laboratory. This study sought to evaluate the reproducibility of QFR when analyzed offline in two independent core
