Objectives: This study compared the diagnostic performance with adenosine-derived
fractional flow reserve (FFR)≤ 0.8 of contrast-based FFR (cFFR), resting distal pressure …

Background—We studied the hemodynamic response to intravenous adenosine on
calculation of fractional flow reserve (FFR). Intravenous adenosine is widely used to achieve …

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

Background—Measurement of fractional flow reserve (FFR) constitutes the current gold
standard to evaluate the hemodynamic significance of coronary stenoses. Limited data …

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

Objectives: This study sought to define the additional effective radiation dose, procedural
time, and contrast medium needed to obtain fractional flow reserve (FFR) measurements …

Objectives: This study sought to compare fractional flow reserve (FFR) with the
instantaneous wave-free ratio (iFR) in patients with coronary artery disease and also to …

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 Fractional flow reserve (FFR) is a measure of coronary stenosis severity that is
based on pressure measurements obtained at maximal hyperemia. The most widely used …

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