  2. 6. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies

    Author : Gylfi Oskarsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; Cardiovascular system; Kardiovaskulära systemet; fetal asphyxia; transposition of the great arteries; dilated cardiomyopathy; aortic stenosis; child; neonate; adenosine; coronary flow reserve; Doppler; coronary flow;

    Abstract : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. READ MORE

  4. 7. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

    Author : Johannes Töger; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

    Abstract : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. READ MORE

  5. 8. Towards Personalized Models of the Cardiovascular System Using 4D Flow MRI

    Author : Belén Casas Garcia; Tino Ebbers; Jonas Lantz; Petter Dyverfeldt; Carljohan Carlhäll; Frans van de Vosse; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D Flow MRI; Computational modelling; Blood flow; Hemodynamics;

    Abstract : Current diagnostic tools for assessing cardiovascular disease mostly focus on measuring a given biomarker at a specific spatial location where an abnormality is suspected. However, as a result of the dynamic and complex nature of the cardiovascular system, the analysis of isolated biomarkers is generally not sufficient to characterize the pathological mechanisms behind a disease.

  6. 9. Aortic valvular flow : a clinical and experimental doppler echocardiographic study

    Author : Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. READ MORE

  7. 10. Turbulent Flow in Constricted Blood Vessels : Quantification of Wall Shear Stress Using Large Eddy Simulation

    Author : Roland Gårdhagen; Matts Karlsson; Toste Länne; Leif Rune Hellevik; Linköpings universitet; []
    Keywords : ;

    Abstract : The genesis of atherosclerosis has previously been shown to be affected by the frictional load from the blood on the vessel wall, called the wall shear stress (WSS). Assessment of WSS can therefore provide important information for diagnoses, intervention planning, and follow‐up. READ MORE
