Simplified Models of Non-Invasive Fractional Flow Reserve Based on CT Images
Invasive fractional flow reserve (FFR) is the gold standard to assess the functional coronary stenosis. The non-invasive assessment of diameter stenosis (DS) using coronary computed tomography angiography (CTA) has high false positive rate in contrast to FFR. Combining CTA with computational fluid dynamics (CFD), recent studies have shown promising predictions of FFRCT for superior assessment o...
متن کاملBlood oxygen level dependent and adenosine-perfusion imaging correlates to invasive measurement of fractional flow reserve
Background It has been shown that blood oxygen level dependent (BOLD) cardiac magnetic resonance imaging (CMR) is able to detect myocardial perfusion differences. However, validation of BOLD CMR against myocardial perfusion reserve (MPR) and fractional flow reserve (FFR) is lacking. We sought to analyze the potential diagnostic accuracy of BOLD CMR in comparison to invasively measured FFR which...
متن کاملInvasive and non-invasive fractional flow reserve index in validation of hemodynamic severity of intracoronary lesions
This review discusses visual and functional evaluation of the hemodynamic significance of the degree of stenosis in coronary angiography, with respect to the indications for revascularization. The concept of the coronary flow reserve is defined, and the theoretical assumptions of the invasive measurement of the fractional flow reserve (FFR) are presented. In the following part, the publication ...
متن کاملEnd-diastolic fractional flow reserve: comparison with conventional full-cardiac cycle fractional flow reserve.
BACKGROUND Diastolic fractional flow reserve (dFFR) has been shown to be highly sensitive for detection of inducible myocardial ischemia. However, its reliance on measurement of left-ventricular pressure for zero-flow pressure correction, as well as manual extraction of the diastolic interval, has been its major limitation. Given previous reports of minimal zero-flow pressure at end-diastole, w...
متن کاملFractional Flow Reserve: Comparison between Invasive and Non-invasive Methods for Calculation of FFR
The heart disease that affects millions of people worldwide is coronary artery disease. It is caused by a narrowing or blocking of the arteries due to plaque which restricts blood flow, and reduces the amount of oxygen to the heart. Angiogram as a tool, which represents an X-ray examination of the blood vessels in the heart, is traditional tool that aid physicians in the treatment of disease. T...
