Information on coronary physiology and myocardial blood flow (MBF) in patients with suspected angina is increasingly important to inform treatment decisions. A number of different techniques including myocardial perfusion imaging (MPI), noninvasive estimation of MBF, and coronary flow reserve (CFR), as well as invasive methods for CFR and fractional ...

Computed tomography angiography (CCTA)-based calculations of fractional flow reserve (FFR) can improve the diagnostic performance of CCTA for physiologically significant stenosis but the computational resource requirements are high. This study aimed at establishing a simple and efficient algorithm for computing simulated FFR (S-FFR).

Background Myocardial fractional flow reserve (FFR myo ) is a functional index of stenosis severity that can be derived from intracoronary pressure measurements performed during maximal vasodilatation. It is defined as the maximal myocardial perfusion during hyperemia in the presence of a stenosis in the

The objective of this study was to compare quantitative analysis of cardiac magnetic resonance (CMR) perfusion at 1.5 and 3 T against fractional flow reserve (FFR) as measured invasively. FFR is considered by many investigators to be a reliable standard to determine hemodynamically significant coronary artery stenoses.

Does coronary stenting following balloon angioplasty improve myocardial fractional flow reserve?
CardioVascular and Interventional Radiology, 1998Suboptimal distal coronary flow reserve after successful balloon angioplasty has been attributed to angiographically unrecognized inadequate lumen expansion, and adjunct coronary stenting has been shown to improve coronary flow reserve. The aim of this study was to investigate whether myocardial fractional flow reserve (FFRmyo) would increase further ...

To review the literature on the diagnostic accuracy of CT-derived fractional flow reserve (FFRCT) for the evaluation of myocardial ischaemia in patients with suspected or known coronary artery disease, with invasive fractional flow reserve (FFR) as the reference standard.A PubMed, EMBASE, and Cochrane cross-search was performed.

Limitation of fractional flow reserve in evaluating coronary artery myocardial bridge.
The Journal of invasive cardiology, 2008Symptomatic myocardial bridge is treated with medical therapy, but in refractory cases, percutaneous revascularization has been used. We describe two cases to highlight differences in coronary compression and flow pattern, which make the luminal narrowing associated with a myocardial bridge anatomically and physiologically different from the fixed ...
