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

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

The assessment of the functional severity by fractional flow reserve (FFR) provides a
physiologic adjunct to invasive coronary angiography by accurately detecting …

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 …

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

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

Coronary stenosis with lumen diameter reduction greater than 50% is recognized as
coronary artery disease (CAD)[1-4]. Fractional flow reserve (FFR) is an epicardial lesion …

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

The aim of this study was to evaluate a new analytical method for calculating non-invasive
fractional flow reserve (FFRAM) to diagnose ischemic coronary lesions. Patients with …
