  2. 11. Blood flow and cell transport in arteries and medical assist devices

    Author : Niclas Berg; Lisa Prahl Wittberg; Laszlo Fuchs; Mihai Mihaescu; Alessandro Veneziani; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemodynamics; CFD; Artherosclerosis; Thrombosis; Platelet activation; Hemorheology; Platelet margination; Technology and Health; Teknik och hälsa;

    Abstract : The cardiovascular system is responsible for transport of nutrients, oxygen, as well as the cells and molecules making up the immune system. Through the hemostatic system, the body maintains the integrity of the blood vessels, and prevents bleeding. READ MORE

  4. 12. 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.

  5. 13. Extending MRI to the Quantification of Turbulence Intensity

    Author : Petter Dyverfeldt; Tino Ebbers; Krishna Nayak; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence intensity; cardiovascular disease; blood flow; hemodynamics; magnetic resonance imaging; generalized phase-contrast MRI; turbulent flow; Medical technology; Medicinsk teknik; Fluid mechanics; Strömningsmekanik;

    Abstract : In cardiovascular medicine, the assessment of blood flow is fundamental to the understanding and detection of disease. Many pharmaceutical, interventional, and surgical treatments impact the flow. The primary purpose of the cardiovascular system is to drive, control and maintain blood flow to all parts of the body.

  6. 14. Lung Emphysema & Cardiac Function

    Author : Kirsten Jörgensen; Göteborgs universitet; []
    Keywords : emphysema; hemodynamics; ventricular end-diastolic volumes; lung volume reduction; ventricular function; transoesophageal echocardiography; magnetic resonance imaging; diastole; simendan; hypertrophy;

    Abstract : Patients with severe lung emphysema have poor quality of life because of impaired lung function and reduced exercise tolerance. Concomitant heart disease in severe emphysema is well recognised. The prevailing view is that mainly the right side of the heart is involved, while the issue of left ventricular (LV) involvement is less studied. READ MORE

  7. 15. Carbon Dioxide Pneumoperitoneum - Hemodynamic Consequences and Thromboembolic Complications

    Author : Fredrik Lindberg; K G Ljungström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Laparoscopic surgery; carbon dioxide pneumoperitoneum; hemodynamics; coagulation; fibrinolysis; thromboembolic complications; phlebography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : The laparoscopic way of performing general surgical procedures was introduced all over the Western world in a few years around 1990. No previous scientific studies of the safety of this new way of performing general surgery had been undertaken. READ MORE
