Objective: For fractional flow reserve measurement, contrast media can be used as an
alternative for adenosine. However, contrast media with different physical characteristics …

Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional
significance of coronary stenoses, which is more accurate than resting indices and does not …

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

Results: After bolus ic adenosine, 12 lesions of 34 (35.3%) were identified as significant. The
CMR value was 0.86±0.06 (range: 0.71–0.97). There were no significant differences …

Background Fractional flow reserve (FFR) measurement requires adenosine injection.
However, adenosine can induce conductive and rhythmic complications, or be …

Objective Measuring the fractional flow reserve (FFR) requires the induction of coronary
hyperemia, usually with adenosine, adenosine triphosphate (ATP), or papaverine. However …

Aims The need of adenosine administration for the achievement of maximal hyperaemia
limits the widespread application of fractional flow reserve (FFR) in the real world. We …

Background Contrast-flow quantitative flow ratio (cQFR) is a recently developed technique to
calculate fractional flow reserve (FFR) from invasive coronary angiography (ICA), obviating …

Background The need for adenosine administration to achieve maximal hyperaemia limits
the widespread application of fractional flow reserve (FFR) in the real world. We previously …

Background: The decrease in fractional flow reserve (FFR) after adenosine administration
from baseline FFR value (termed as ΔFFR) may reflect the compensatory capacity of the …
