  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. 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

  4. 3. 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.

  5. 4. Aortic Valve Replacement: The Influence of Prosthesis-Patient Mismatch for Left Ventricular Remodeling, Cardiac Function and Survival

    Författare :Shahab Nozohoor; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prosthesis-Patient Mismatch; Left Ventricular Remodeling; Survival; Aortic valve replacement;

    Sammanfattning : The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable prosthesis-patient mismatch (PPM). 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
