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 …

Objectives: This study sought to compare increasing doses of intracoronary (IC) adenosine
or IC sodium nitroprusside versus intravenous (IV) adenosine for fractional flow reserve …

We read with interest the article by van de Hoef and colleagues about the value of the
coronary stenosis pressure drop-flow velocity ratio (ΔP/V) in the evaluation of coronary …

Objectives: FFR measurement performed at the end of a diagnostic angiogram, allows to
obtain functional information on top of the anatomic findings (all-in-one approach). We …

Fractional flow reserve (FFR) is a reference invasive diagnostic test to assess the
physiological significance of an epicardial coronary artery stenosis. FFR-guided …

Fractional flow reserve (FFR) is an evidence-based diagnostic tool of physiological
significance of coronary artery stenosis in patients with stable coronary artery disease …

Objectives: The aim of this study was to compare site-reported measurements of fractional
flow reserve (FFR) with FFR analysis by an independent core laboratory (CL). Background …

Background Since the publication of the “ FAME” study, the use of the
pressure wire has increased. Intravenous adenosine (IV) is considered the standard method …

Background Administration of intracoronary (IC) adenosine allows an easily feasible,
inexpensive, and more rapid alternative method for fractional flow reserve (FFR). It is …

Objectives: This study classified and quantified the variation in fractional flow reserve (FFR)
due to fluctuations in systemic and coronary hemodynamics during intravenous adenosine …
