Diagnostic Performance of QFR for the Evaluation of Intermediate Coronary Artery Stenosis Confirmed by Fractional Flow Reserve
Introduction: Quantitative flow ratio (QFR) is a novel method enabling efficient
computation of FFR from three-dimensional quantitative coronary angiography
(3D QCA) and thrombolysis in myocardial infarction (TIMI) frame counting. We
decided to perform a systematic review and quantitative meta-analysis of the
literature to determine the correlation between the diagnosis of
functionally significant stenosis obtained by QFR versus FFR and to
determine the diagnostic accuracy of QFR for intermediate coronary artery
stenosis.Methods: We searched PubMed, Embase, and Web of Science for studies concerning the
diagnostic perfo ...
