Computations of fractional flow reserve based on CT coronary angiography and computational fluid dynamics CT-based FFR to assess the severity of coronary artery stenosis was introduced around a decade ago and is now one of the most successful applications of computational fluid dynamic modelling in clinical practice. The Impact Of Revascularization Related By Blood Fractional Flow Reserve Calculated By Coronary Artery CTA On Prognosis. Calculation of fractional flow reserve HeartFlow FFR CT for persons who have a coronary CTA that has shown coronary artery disease of uncertain functional significance or is non-diagnostic.
Since CT-based fractional flow reserve research so far has only been performed with stable patients and non-acute cases its accuracy in patients with acute coronary syndrome remains unknown. FFR CT should always be interpreted in correlation. Furthermore the post-processing.
This technology has been demonstrated from several clinical trials that Fractional flow reserve CT is a more superior diagnostic imaging modality than the traditional coronary CTA in detecting coronary artery disease. FFRCT should always be interpreted in. Detection of coronary ischemic lesions by fractional flow reserve FFR has been established as the gold standard.
The recent introduction of a novel computational method has enabled the calculation of fractional flow reserve FFR CT from cardiac computed tomography CT imaging data without the need for additional imaging medication or modification of CT acquisition protocols. The aim of our study was to assess whether CT-derived fractional flow reserve CT-FFR allows for differentiation of hemodynamically significant and non-significant coronary stenosis in. Fractional flow reserve is defined as the pressure after distal to a stenosis relative to the pressure before the stenosis.
