  1. 1. Hemocompatibility of materials for use in prosthetic heart valves

    Författare :Yanqi Yang; Eric G. Butchart; Linköpings universitet; []
    Nyckelord :Heart valve prosthesis; mechanical heart valves; bioprosthetic heart valves; biomaterials; hemocompatibility; blood-material interaction; in vivo test; MEDICINE; MEDICIN;

    Sammanfattning : Thromboembolism (valve thrombosis and systemic embolism) is the main drawback of mechanical heart valve prostheses. The patients carrying these valves have to be subjected to life-long anticoagulant therapy to reduce thromboembolism. LÄS MER

  3. 2. Epidemiological studies of bioprosthetic aortic valves

    Författare :Michael Dismorr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The use of bioprosthetic valves is common and offers a prosthetic option that does not require anti-coagulant therapy, but with shorter valve longevity compared to mechanical prostheses. Valve model selection might influence the long-term performance of the prosthesis. LÄS MER

  4. 3. Studies on glycosphingolipids in regenerative medicine

    Författare :Angela Barone; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glycosphingolipids; human embryonic stem cells; Cell surface markers; porcine heart valves; xenotransplantation; regenerative medicinr;

    Sammanfattning : Regenerative medicine, including stem cell based therapies and xenotransplantation, is a new and developing field that aims to restore normal function in end stage cell/organ failure. However, in therapeutic settings involving transfer of cells with a different genetic background, these cells will expose the recipient to non-self cell surface antigenic determinants that may evoke an immune response and subsequent graft damage.

  5. 4. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

    Författare :Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

    Sammanfattning : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. LÄS MER
