Background: The resting distal-to-aortic coronary pressure ratio (Pd/Pa) is a universally
available, hyperemia-free physiological index of coronary stenosis. We investigated clinical …

Before addressing study specifics, it is worthwhile to consider how the image (eg,
angiographic, intravascular ultrasound, or OCT) derived pressure or flow models work …

Andreas Gruentzig's invention of coronary balloon angioplasty (now called percutaneous
coronary intervention [PCI]) revolutionized the field of cardiovascular medicine, bringing …

Abstract Purpose of Review Just over four decades ago, the management of coronary artery
disease (CAD) witnessed a major breakthrough with the advent of minimally invasive …

Aims: The aim of this study was to evaluate the predictability of resting distal coronary
pressure wave forms for fractional flow reserve (FFR). Methods and results: Resting …

Objectives We sought to develop an automatic method for correcting common errors in
phasic pressure tracings for physiology‐guided interventions on coronary and valvular …

Background The phenomenon of “pressure drift” increases uncertainty about the correct FFR
value. Redesigned and incorporating an optical pressure sensor, the “OptoWire Deux™” is …

Invasive fractional flow reserve (FFR) adoption remains low mainly due to procedural and
operator related factors as well as costs. Alternatively, quantitative flow ratio (QFR) achieves …

Background: The only indication for coronary revascularization is elimination of ischaemia.
Invasive hemodynamic methods (fractional flow reserve–FFR and instantaneous wave-free …
