  1. 1. Heart Valve Surgery : Preoperative Assessment and Clinical Outcome

    Författare :Laila Hellgren; Elisabeth Ståhle; Mårten Rosenquist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Heart valve surgery; magentic resonance imaging; echocardiography; operative mortality; survival; complications; quality of life; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : A more global analysis of the outcome of heart valve surgery is desirable to reflect the actual benefit for the patient. This thesis focuses on the preoperative assessment of the patient, and the outcome after surgery with regard to operative mortality, long-term survival, valve-related complications, and quality of life.

  3. 2. Anticoagulation treatment in patients with a mechanical heart valve

    Författare :Bartosz Grzymala-Lubanski; Anders Själander; Peter J. Svensson; David Bergqvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical heart valve; anticoagulation; warfarin; Time in Therapeutic Range TTR ; INR variability;

    Sammanfattning : BackgroundEvery year about 2,500 patients in Sweden undergo surgery for heart valve disease, primarily in the aortic valve.  In contrast to the mitral valve, which can be repaired in 70% of the cases, the aortic valve is normally replaced by a mechanical or biological prosthesis.

  4. 3. 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

  5. 4. Management of Adults with Congenital Heart Disease

    Författare :Daniel Samarai; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adults with Congenital Heart Disease; Congenital Heart Disease; Congenital heart defect CHD ; Anticoagulation; Anticoagulants; anticoagulant treatment; Thromboembolic events; Major bleeding; Diagnostic Imaging methods;

    Sammanfattning : Adults with congenital heart disease (ACHD) are a completely new and rapidly growing specialty comprising patients who require specialist knowledge regarding their care and treatment. Challenges involve diagnostics and treatment as studies are scarce and include small and heterogenous study populations. LÄS MER

  7. 5. Prosthetic aortic heart valves

    Författare :Natalie Glaser; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Aortic valve replacement (AVR) can be performed with different types of valve prostheses. There is no perfect aortic valve prosthesis, and the prosthetic choice for each patient requires careful consideration. This thesis evaluates mortality, morbidity, and prosthetic valve function after AVR with different aortic valve prostheses. LÄS MER
