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 …

Fractional flow reserve (FFR) determined by invasive angiography is the gold standard to
assess the severity of coronary artery disease (CAD). FFRCT can be obtained non …

Computed tomography angiography (CCTA)-based calculations of fractional flow reserve
(FFR) can improve the diagnostic performance of CCTA for physiologically significant …

Revascularization of coronary artery stenosis should be based on the objective evidence of
ischemia. It is common practice for physicians to make decisions on revascularization in the …

Coronary artery disease causes significant morbidity and mortality worldwide. Invasive
coronary angiography (ICA) is currently the reference standard investigation. Fractional flow …

Aims: The aim of this study was to validate novel software to calculate vessel fractional flow
reserve (vFFR) based on 3D-QCA and to assess inter-observer variability in patients who …

Background Fractional flow reserve (FFR), in previous studies showing high reproducibility,
is the gold standard for determining the hemodynamic significance of coronary lesions. Non …

Invasive fractional flow reserve (FFR invasive), although gold standard to identify
hemodynamically relevant coronary stenoses, is time consuming and potentially associated …

BACKGROUND Based on coronary angiography and mean aortic pressure, a specially
designed computational flow dynamics (CFD) method is proposed to determine contrast …

Aims To evaluate diagnostic accuracy of quantitative flow ratio (QFR). A novel method was
used for non-invasive functional assessment of intermediate coronary lesions. Fractional …
