Health professionals are encouraged to take the ESC Guidelines fully into account when
exercising their clinical judgment, as well as in the determination and the implementation of …

In this review, the authors reflect upon the role of coronary physiology in the modern
management of coronary artery disease. They critically appraise the scientific background of …

Background The instantaneous wave-free ratio (iFR) is an index used to assess the severity
of coronary-artery stenosis. The index has been tested against fractional flow reserve (FFR) …

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

Radionuclide myocardial perfusion imaging (MPI) is among the most commonly performed
diagnostic tests in cardiology. Although the diagnostic and prognostic applications of …

Objectives: This study sought to evaluate the incidence and causes of an abnormal
instantaneous wave-free ratio (iFR) after angiographically successful percutaneous …

Background—Quantitative flow ratio (QFR) is a novel diagnostic modality for functional
testing of coronary artery stenosis without the use of pressure wires and induction 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 …

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