Coronary angiography provides excellent visualization of coronary arteries, but has
limitations in assessing the clinical significance of a coronary stenosis. Fractional flow …

Fractional flow reserve (FFR) is an important prognostic determinant in a clinical setting.
However, its measurement currently requires the use of invasive pressure wire, while an …

Background: A new method for calculating fraction flow reserve (FFR) without pressure-wire
(angiography-derived FFR) based on invasive coronary angiography (ICA) images can be …

Background—Fractional flow reserve (FFR), an index of the hemodynamic severity of
coronary stenoses, is derived from invasive measurements and requires a pressure …

Fractional flow reserve (FFR) has become an important quantitative-index for defining the
physiologic significance of coronary stenosis. Pressure-wire based FFR is being …

Objectives Catheter-based angiography is the reference-standard to establish coronary
anatomy. While routinely employed clinically, lumen assessment correlates poorly with …

Fractional flow reserve (FFR) provides an objective physiological evaluation of stenosis
severity. A technique that can measure FFR using only angiographic images would be a …

Coronary flow reserve (CFR) and fractional flow reserve (FFR) are important physiological
indexes for coronary disease. The purpose of this study was to validate the CFR and FFR …

Background: Measuring fractional flow reserve (FFR) with a pressure wire remains
underutilized because of the invasiveness of guide wire placement or the need for a …

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