The fundamental limitations of conventional coronary angiography and its poor correlation
with severity of functional stenosis has been well established [1]. Using pressure-derived …

Background Adenosine induced hyperaemic fractional flow reserve (aFFR) is a validated
predictor of clinical outcome and part of routine interventional practice. Protocol issues …

Coronary angiography alone cannot accurately identify the haemodynamic impact of a
coronary artery stenosis. Current international guidelines for myocardial revascularization …

Fractional flow reserve (FFR) can be measured during routine coronary angiography using a
pressure wire to calculate the ratio of the mean distal coronary artery pressure to the aortic …

Fractional flow reserve (FFR) has been recognized as an effective tool to determine
functional significance in intermediate coronary lesions and FFR‐guided percutaneous …

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

Aims: Defining the clinical and physiologic significance of an intermediate coronary artery
stenosis is aided by measurement of fractional flow reserve (FFR). Adenosine is the most …

Aim To review the current approaches to simplify functional assessment of coronary stenosis
with particular regard for contrast Fractional Flow Reserve (cFFR). Methods and results …

Background Injection of contrast media induces sub-maximal levels of hyperemia and
allows for rapid measurement of contrast FFR (cFFR) without the side effects or time …

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