Lesion Eccentricity and Fractional Flow Reserve and Coronary Flow Reserve in Coronary Arteries
2013Fractional flow reserve has shown to be a gold standard in assessment of functional significance of coronary artery stenosis. Lesion eccentricity is an important geometric parameter which may affect the translational hemodynamics. Three dimensional quantitative coronary angiography (3D-QCA) was used to reconstruct the proximal or mid left anterior ...

Coronary vasomotion and coronary flow reserve during exercise
1991Coronary vasomotion and coronary blood flow are important determinants of myocardial perfusion in patients with coronary artery disease. New digital angiographic techniques allow to study, not only the dimensions of a stenotic lesion (quantitative coronary arteriography), but also coronary flow reserve (parametric imaging).

Coronary Flow Resistance and Reserve
2015The coronary arteries are the initial vessels off of the aorta and eventually end in a rich capillary bed that provides blood to the myocytes in a one to one fashion (one capillary for each myocyte.) The myocardial oxygen concentration is at maximum such that any increase in myocardial blood flow (MBF) can only be accomplished by increase in coronary ...

Coronary flow reserve and fractional flow reserve
Coronary flow reserve (CFR) and fractional flow reserve (FFR) are two methods used to provide information for functional significance of coronary artery stenosis. Despite having some limitations, both parameters not only designate severity of stenosis but also provide prognostic information when they are used within appropriate indications.Ozyol, Ali, Yilmaz, Mehmet Birhan

Coronary Blood Flow and Coronary Vascular Reserve
1989The severity of coronary artery disease (CAD) has traditionally been evaluated by assessing coronary artery anatomy and left ventricular function during cardiac catheterization. The reduction in coronary artery blood flow caused by a particular stenosis has been inferred from its appearance on coronary arteriography.1 It is now well known that the ...
