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

Aims Conventional fractional flow reserve (FFR) is measured invasively using a coronary
guidewire equipped with a pressure sensor. A non-invasive derived FFR would eliminate …

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: Angiographic fractional flow reserve (angioFFR) is a novel artificial intelligence
(AI)-based angiography-derived fractional flow reserve (FFR) application. We investigated …

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 …

Assessment of the functional significance of coronary artery stenosis using invasive
measurement of fractional flow reserve (FFR) or non-hyperemic indices has been shown to …

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

Background Contrast-flow quantitative flow ratio (cQFR) is a recently developed technique to
calculate fractional flow reserve (FFR) from invasive coronary angiography (ICA), obviating …

Background Fractional flow reserve (FFR) is a widely used gold standard to evaluate
ischemia-causing lesions. A new method of non-invasive approach, termed as AccuFFRct …

Background Non-invasive fractional flow reserve (FFR) has been increasingly used in the
clinical workflow to assist clinical decision-making for percutaneous coronary intervention …
