Fractional flow reserve (FFR) is emerging as a useful clinical tool for assessing the
functional significance of coronary atherosclerosis. As opposed to anatomical approaches …

Background Quantitative flow ratio (QFR) is a novel modality for physiological lesion
assessment based on 3‐dimensional vessel reconstructions and contrast flow velocity …

Objectives: This study sought to determine if adenosine administration is required for the
pressure-only assessment of coronary stenoses. Background: The instantaneous wave-free …

BACKGROUND: The achievement of maximal vasodilatation of the coronary microvessels is
mandatory for the accurate determination of fractional flow reserve (FFR); the optimal dosing …

Background The role of resting pressure parameters, ie instantaneous wave-free ratio (iFR),
and resting distal coronary pressure/aortic pressure (Pd/Pa) in assessing functionally …

Fractional flow reserve (FFR) has been applied with success as a lesion‐specific functional
indicator of stenosis severity, at least in patients with normal microcirculation. This study …

Background—Measurement of fractional flow reserve (FFR) to guide coronary
revascularization lags despite robust supportive data, partly because of the handling …

Aims Pressure-wire assessment of coronary stenosis is considered the invasive reference
standard for detection of ischaemia-generating lesions. Recently, methods to estimate the …
