Measurement of fractional flow reserve (FFR) at the time of invasive coronary angiography is
an established method for the assessment of epicardial coronary lesion severity …

Quantitative coronary angiography (QCA) is commonly referred to as the “gold standard” for
an accurate assessment of the epicardial coronary artery diameter stenosis severity in …

In this issue of JACC: Cardiovascular Interventions, Tu et al.(1) report on an initial validation
study for a less-invasive approach to derive fractional flow reserve (FFR) based on the …

Different non-invasive and invasive imaging modalities are currently available for the
diagnosis of coronary artery disease (CAD) and subsequent management decisions in …

Evidence robustly demonstrates that ischemia, rather than anatomy, is the optimal target for
coronary revascularization. In the cardiac catheter laboratory, fractional flow reserve (FFR) …

Background FFRangio and QFR are angiography-based technologies that have been
validated in patients with stable coronary artery disease. No head-to-head comparison to …

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

Background: Fractional flow reserve (FFR) is the gold standard of functional assessment of
intermediate lesions. Interrogating the stenosis with pressure-wire prolongs procedure …

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