Jelmer Westra,Birgitte Krogsgaard Andersen,Gianluca Campo,Hitoshi Matsuo,Lukasz Koltowski,Ashkan Eftekhari,Tommy Liu,Luigi Di Serafino,Domenico Di Girolamo,Javier Escaned,Holger Nef,Christoph Naber,Marco Barbierato,Shengxian Tu,Omeed Neghabat,Morten Madsen,Matteo Tebaldi,Toru Tanigaki,Janusz Kochman,Samer Somi,Giovanni Esposito,Giuseppe Mercone,Hernán Mejía-Rentería,Federico Ronco,Hans Erik Bøtker,William Wijns,Evald Høj Christiansen,Niels Ramsing Holm +27 more
TL;DR: Online computation of QFR in the catheterization laboratory is clinically feasible and is superior to angiographic assessment for evaluation of intermediary coronary artery stenosis using FFR as a reference standard.
Journal ArticleDOI
Diagnostic performance of quantitative flow ratio in prospectively enrolled patients: An individual patient-data meta-analysis.

TL;DR: This work aimed to provide robust performance estimates for quantitative flow ratio (QFR) in assessment of intermediary coronary lesions with high confidence in terms of accuracy and consistency.
Journal ArticleDOI
Reproducibility of Quantitative Flow Ratio: The QREP Study.

TL;DR: In this paper, the reproducibility of quantitative flow ratio (QFR) computed from the same angiograms as assessed by multiple observers from different, international sites was evaluated.
Journal ArticleDOI
Resting distal to aortic pressure ratio and fractional flow reserve discordance affects the diagnostic performance of quantitative flow ratio: Results from an individual patient data meta-analysis.

TL;DR: To evaluate the diagnostic performance of quantitative flow ratio (QFR) related to fractional flow reserve (FFR) and resting distal‐to‐aortic pressure ratio (resting Pd/Pa) concordance, a parallel study of QFR and FFR is presented.
