Background Fractional flow reserve (FFR) and optical coherence tomography (OCT) may
help both in assessment and in percutaneous coronary intervention optimization of …

Background Measurement of fractional flow reserve (FFR) has become a standard
diagnostic tool in the catheterization laboratory. FFR evaluation studies were based on …

Background Fractional flow reserve (FFR)-derived from computed tomography angiography
(CTA; FFRCT) and invasive FFR (FFRINV) are used to assess the need for invasive …

Objective We aimed to evaluate the determinants of visual‐functional mismatches between
quantitative coronary angiography (QCA) and the quantitative flow ratio (QFR). Background …

Aims Guidelines recommend the use of fractional flow reserve (FFR) to guide percutaneous
coronary intervention. For this purpose, physiological lesion assessment without adenosine …

Background Introduction: There has been a recent interest in fractional flow reserve
measurements derived from computed tomography (CT-FFR) to evaluate the degree of …

Background Instantaneous wave free ratio (iFR) does not require adenosine, but has a
relatively wide intermediate range where functional assessment remains inconclusive. In …

Background: The significance of a coronary stenosis can be determined by measuring the
fractional flow reserve (FFR) during invasive coronary angiography. Recently, novel …

Background Fractional flow reserve (FFR) is the ratio of blood pressure measured distal to a
stenosis and pressure proximal to a stenosis. FFR can be estimated noninvasively using …

AIMS: Adenosine administration is needed for the achievement of maximal hyperaemia
fractional flow reserve (FFR) assessment. The objective was to test the accuracy of Pd/Pa …
