BACKGROUND: Achievement of maximal hyperemia of the coronary microcirculation is a
prerequisite for the measurement of fractional flow reserve (FFR). Intravenous adenosine is …

Pressure-based fractional flow reserve (FFR) is used clinically to evaluate the functional
severity of a coronary stenosis, by predicting relative maximal coronary flow (Qs/Qn). It is …

Fractional flow reserve (FFR) and instantaneous wave-free ratio are the present standard
diagnostic methods for invasive assessment of the functional significance of epicardial …

Fractional flow reserve (FFR) is an invasive procedure used during coronary angiography to
determine the functional significance of coronary stenoses. Its use is particularly helpful in …

Background: Fractional flow reserve (FFR) has become an established tool for guiding
treatment, but its graded relationship to clinical outcomes as modulated by medical therapy …

Background: Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) disagree
on the hemodynamic significance of a coronary lesion in≈ 20% of cases. It is unknown …

Objectives: This study investigated the prognostic implication of coronary flow reserve (CFR)
in patients who underwent fractional flow reserve (FFR) measurement. Background: Limited …

Introduction Fractional flow reserve (FFR) measured after percutaneous coronary
intervention (PCI) has been identified as a surrogate marker for vessel related adverse …

Background—Discordance between fractional flow reserve (FFR) and coronary flow velocity
reserve (CFVR) may reflect important coronary pathophysiology but usually remains …

Fractional flow reserve (FFR) is a useful modality to assess the functional significance of
coronary stenoses. Although adenosine triphosphate (ATP) is generally used as the …
