Aims Fractional flow reserve measurement is based upon achieving maximum hyperemia. A
40 microg intracoronary (IC) adenosine bolus sometimes seems insufficient, and we …

Direct intracoronary adenosine bolus is an excellent alternative to intravenous adenosine
fractional flow reserve (FFR) measurement. This study, during four increasing adenosine …

Objectives We performed this study to evaluate the variability of fractional flow reserve (FFR)
values which were measured from various methods of hyperemia induction. Background …

Methods: In total, 23 publication representing results of more than 4000 patients comparing
QFR and FFR reproducibility and agreement were studied. Results: Agreement between …

Introduction Functional Flow Reserve (FFR) is the standard for haemodynamic assessment
of intermediate-grade coronary stenosis. The current focus of research is on developing …

Background Measurement of fractional flow reserve (FFR) has become a standard
diagnostic tool in the catheterization laboratory. FFR evaluation studies were based on …

Background: Achievement of maximal hyperemia is mandatory for an accurate calculation of
fractional flow reserve (FFR) and it is obtained with adenosine given either as an …

Purpose: Intravenous (IV) adenosine is widely used to achieve stable hyperaemia for
measurement of fractional flow reserve (FFR). However, IV adenosine affects both systemic …

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 …

Background Revascularization of intermediate coronary artery stenosis guided by the
fractional flow reserve (FFR) improves clinical outcomes and is therefore recommended by …
