Prognostic Value of Postpercutaneous Coronary Intervention Murray-Law-Based Quantitative Flow Ratio [PDF]

JACC: Asia
Background: Coronary physiology measured by fractional flow reserve (FFR) is superior to angiography for assessing the efficacy of percutaneous coronary intervention (PCI). Yet, the clinical adoption of post-PCI FFR is limited.

Quantitative flow ratio will supplant wire-based physiological indices: pros and cons. [PDF]

EuroIntervention
Quantitative flow ratio (QFR) represents a physiological index derived from angiography through three-dimensional (3D) quantitative coronary analysis. When compared to coronary angiography, QFR showed better performance both for guiding percutaneous coronary intervention (PCI) in case of intermediate coronary lesions and for optimising PCI results.

Diagnostic performance of the quantitative flow ratio and CT-FFR for coronary lesion-specific ischemia [PDF]

Scientific Reports
Fractional flow reserve (FFR) has become the gold standard for evaluating coronary lesion-specific ischemia. However, FFR is an invasive method that may cause possible complications in the coronary artery and requires expensive equipment, which limits ...

Diagnostic agreement of quantitative flow ratio with fractional flow reserve in a Latin-American population [PDF]

The International Journal of Cardiovascular Imaging, 2022
Quantitative flow ratio (QFR) is a recently proposed angiographic index that allows to assess the pressure loss in coronary arteries in a similar fashion as the fractional flow reserve (FFR). The purpose of this study was to evaluate the diagnostic performance of QFR as compared to FFR, in a Latin-American population of patients with suspected ...

Reproducibility of quantitative flow ratio: the QREP study

EuroIntervention, 2022
Quantitative flow ratio (QFR) is a tool for physiological lesion assessment based on invasive coronary angiography.We aimed to assess the reproducibility of QFR computed from the same angiograms as assessed by multiple observers from different, international sites.We included 50 patients previously enrolled in dedicated QFR studies.
