Quantification of myocardial perfusion reserve at 1.5 and 3.0 Tesla: a comparison to fractional flow reserve

The International Journal of Cardiovascular Imaging, 2012
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.

Fractional Flow Reserve

Circulation, 1995
Background Fractional flow reserve (FFR), defined as the ratio of maximum flow in the presence of a stenosis to normal maximum flow, is a lesion-specific index of stenosis severity that can be calculated by simultaneous measurement of mean arterial, distal coronary, and central venous pressure (P a , P

Catheterization and cardiovascular interventions, 2019
There are limited data on the use of intravascular ultrasound (IVUS), optical coherence tomography (OCT), and fractional flow reserve (FFR) during acute myocardial infarction (AMI).

Outcomes after fractional flow reserve-guided percutaneous coronary intervention versus coronary artery bypass grafting (FAME 3): 5-year follow-up of a multicentre, open-label, randomised trial.

The Lancet
BACKGROUND Long-term outcomes following percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) might be changing because of improved techniques and better medical therapy.

Myocardial Fractional Flow Reserve and Clinical Outcome

1997
There is ample inferential evidence that patients with physiologically significant stenoses are at increased risk1. Patients with proven coronary artery disease and in whom signs of myocardial ischemia are observed at low workload have an adverse event rate which is four times higher than in those with similarly severe stenoses but in whom ischemia can

The temporal recovery of fractional flow reserve, coronary flow reserve and index of microcirculatory resistance following myocardial infarction

Current Opinion in Cardiology, 2015
The purpose of this review was to summarize the healing processes after myocardial infarction (MI) and to relate these temporal changes to data from serial imaging obtained by cardiac magnetic resonance, and then to relate these findings to the invasive measures of the indices of coronary physiology (e.g., fractional flow reserve, coronary flow reserve

Reasons and implications of agreements and disagreements between coronary flow reserve, fractional flow reserve, and myocardial perfusion imaging

Journal of Nuclear Cardiology, 2018
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 ...

The diagnostic performance of CT-derived fractional flow reserve for evaluation of myocardial ischaemia confirmed by invasive fractional flow reserve: a meta-analysis

Clinical Radiology, 2015
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.

The association of coronary lumen volume to left ventricle mass ratio with myocardial blood flow and fractional flow reserve.

Journal of cardiovascular computed tomography, 2019
BACKGROUND A diminished coronary lumen volume to left ventricle mass ratio (V/M) derived from coronary computed tomography angiography (CCTA) has been proposed as factor contributing to impaired myocardial blood flow (MBF) even in the absence of ...
