Multi-scale computational modeling of coronary blood flow: application to fractional flow reserve.
Introduction. Fractional flow reserve (FFR) is presently an invasive coronary clinical index. Non-invasive CT imaging combined with computational coronary flow modelling may reduce the patient’s burden of undergoing invasive testing. Research statement. The ability to obtain information of the …

Validation of first pass magnetic resonance myocardial perfusion imaging using fractional flow reserve
Background - Magnetic Resonance Myocardial Perfusion Imaging (MRMPI) has been used for the detection of reversible myocardial ischaemia in humans since the early 1990’s. This non-invasive method of diagnosing reversible myocardial ischaemia has a number of advantages over the other more commonly …

Comparison of clinical outcome after revascularization versus conservative treatment in patients with borderline fractional flow reserve measurements
BACKGROUND: Measurement of fractional flow reserve (FFR) is useful tool for assessing the functional severity of coronary artery stenosis and for clinical decision of treatment strategy. Many studies have shown that FFR measurement <0.75 is specific for ischemia, but there is a controversy about …

Relationship Between Intravascular Ultrasound Parameters and Fractional Flow Reserve in Intermediate Coronary Artery Stenosis of Left Anterior Descending Artery
… parameters, including volumetric analysis, and fractional flow reserve (FFR). METHODS: Both IVUS and FFR were performed in 206 cases of intermediate stenosis of the left anterior descending artery (LAD). Myocardial ischemia was assessed by FFR and maximal hyperemia was induced by continuous …

The relationship between intravascular ultrasound-derived percent total atheroma volume and fractional flow reserve in the intermediate stenosis of proximal or middle left anterior descending coronary artery
… descending artery (LAD). An IVUS study and fractional flow reserve (FFR) measurements performed in 130 patients with coronary angiographic intermediate stenosis of proximal or middle LAD. %TAV was calculated as the percentage of total vessel volume occupied by total atheroma volume on IVUS. …

Improving Coronary Artery Disease Diagnostics with Massively Parallel, Personalized Flow Models and Immersive Treatment Planning.
… driven by local hemodynamic forces, flow-generated endothelial shear stress (ESS), and pressure-derived tensile stress. These hemodynamic forces can be derived from sophisticated computational fluid dynamics (CFD) simulations. Personalized 3D CFD simulations based on patient-specific …

Non-invasive Cardiovascular Magnetic Resonance Imaging in Patients with Ischemic Heart Disease
… imaging approach to the reference standard of fractional flow reserve (FFR) in 37 patients with suspected or known CAD. OS-CMR did identify abnormal myocardium supplied by coronary arteries with hemodynamically limiting stenoses, confirming a role for OS-CMR in the evaluation of myocardial …

Invasive Physiologic Assessment of Myocardial Viability After Primary Angioplasty in Acute Myocardial Infarction: Comparison With FDG-PET Imaging
… After successful PCI, Doppler-derived coronary flow reserve (CFRDoppler), microvascular resistance index (MVRI) and phasic coronary flow velocity patterns were evaluated. Using a pressure-temperature sensor-tipped coronary wire, thermodilution-derived CFR (CFRthermo), fractional flow reserve …
