Physiological assessment of coronary artery disease (CAD) has become one of the
cornerstones of decision making for myocardial revascularization, with a large body of …

Aims: Randomised controlled trials have reported instantaneous wave-free ratio (iFR) to be
non-inferior to fractional flow reserve (FFR) for major adverse cardiovascular events at one …

Background: Pressure measurement for the duration of the wave-free period (WFP) is
considered essential for resting-state physiological assessment of coronary stenosis severity …

Objectives”, explains how to select and use various test methods for evaluating disease
states, the prognosis, and the effects of treatment. References to the literature published …

Although revascularization has been one of the primary treatment options for obstructive
coronary artery disease (CAD) for about 50 years, the evidence base for its use is most …

Background: We evaluated the 2-year clinical outcomes of deferred lesions with discordant
results between resting and hyperemic pressure-derived physiologic indices, including …

Objectives: This study sought to evaluate the prognostic value of post–percutaneous
coronary intervention (PCI) distal coronary pressure to aortic pressure ratio (Pd/Pa) in …

Background Quantitative flow ratio (QFR) is a novel, adenosine-free method for functional
coronary lesion interrogation, which is based on 3-dimensional quantitative coronary …

Objectives This study sought to investigate the prognostic implications of post–percutaneous
coronary intervention (PCI) nonhyperemic pressure ratios compared with that of post-PCI …

Objective The primary objective was to demonstrate diagnostic equivalence between RFR
and iFR in clinical practice. Background The instantaneous wave‐free ratio (iFR), a …
