  1. 1. Patient-Specific Finite Element Modeling of the Blood Flow in the Left Ventricle of a Human Heart

    Författare :Jeannette Hiromi Spühler; Johan Hoffman; Johan Jansson; Mariano Vazquez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finite element method; Arbitrary Lagrangian-Eulerian method; Fluid-Structure interaction; Contact model; parallel algorithm; blood flow; left ventricle; aortic valves; patient-specific heart model;

    Sammanfattning : Heart disease is the leading cause of death in the world. Therefore, numerous studies are undertaken to identify indicators which can be applied to discover cardiac dysfunctions at an early age. LÄS MER

  3. 2. Analysis of cardiac cell turnover in humans by radiocarbon dating and mathematical modeling

    Författare :Sofia Zdunek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease is the largest cause of morbidity and mortality in the Western World. Disease progression often involves a loss of contracting cells, cardiomyocytes, which leads to cardiac failure and the need for heart transplantation with time. LÄS MER

  4. 3. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Författare :Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER

  5. 4. Blood flow and cell transport in arteries and medical assist devices

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

    Sammanfattning : 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. LÄS MER
