Objectives We aimed to provide robust performance estimates for quantitative flow ratio
(QFR) in assessment of intermediary coronary lesions. Background Angiography‐based …

Background: Quantitative flow ratio (QFR) is a novel angiography-based method for deriving
fractional flow reserve (FFR) without pressure wire or induction of hyperemia. The accuracy …

Introduction Despite of the wide evidence of use fractional flow reserve (FFR), isolated
angiography evaluation is still the main tool to indicate percutaneous coronary intervention …

Background Quantitative flow ratio (QFR) is a tool for physiological lesion assessment based
on invasive coronary angiography. Aims We aimed to assess the reproducibility of QFR …

Background Quantitative flow ratio (QFR) is a novel modality for physiological lesion
assessment based on 3‐dimensional vessel reconstructions and contrast flow velocity …

Objectives The aim of this prospective multicenter study was to identify the optimal approach
