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

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 …

Objectives This study sought to assess the diagnostic performance of FFRangio (CathWorks,
Kfar Saba, Israel), an angiogram-derived fractional flow reserve (FFR) technology …

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

Background: Quantitative flow ratio (QFR) is a newly developed image-based index for
estimating fractional flow reserve (FFR). Methods and Results: We analyzed 151 coronary …

Abstract Purpose of Review Three-dimensional quantitative coronary angiography-based
methods of fractional flow reserve (FFR) derivation have emerged as an appealing …

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

Objectives: The aim of this study was to develop a computer model that accurately predicts
myocardial fractional flow reserve (FFR) from angiographic images alone, in patients with …

Aims Pressure-wire assessment of coronary stenosis is considered the invasive reference
standard for detection of ischaemia-generating lesions. Recently, methods to estimate the …

Objectives: This study sought to present a novel computer model for fast computation of
myocardial fractional flow reserve (FFR) and to evaluate it in patients with intermediate …
