Aims The present analysis addresses the potential clinical and physiologic significance of
discordance in severity of coronary artery disease between the angiogram and fractional …

Background—Discordance between fractional flow reserve (FFR) and coronary flow velocity
reserve (CFVR) may reflect important coronary pathophysiology but usually remains …

Fractional flow reserve (FFR) is considered nowadays as the gold standard for invasive
assessment of physiologic stenosis significance and an indispensable tool for decision …

Fractional flow reserve (FFR) is an invasive procedure used during coronary angiography to
determine the functional significance of coronary stenoses. Its use is particularly helpful in …

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

Background: Among patients with documented stable coronary artery disease and in whom
no revascularization was performed, we compared the respective values of angiographic …

Objectives The aim of this prospective multicenter study was to identify the optimal approach
for simple and fast fractional flow reserve (FFR) computation from radiographic coronary …

Fractional flow reserve (FFR) measurements can determine the haemodynamic relevance of
coronary artery stenoses. Current guidelines recommend their use in lesions in the absence …

Background Quantitative flow ratio (QFR) has a high diagnostic accuracy in assessing
functional stenoses relevance, as judged by fractional flow reserve (FFR). However, its …

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 …
