  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. Outcome and risk factors after aortic valve interventions

    Författare :Per Kvidal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic valve replacement; mechanical valve prosthesis; relative survival; morbidity; recurrent events; balloon aortic valvuloplasty; long-term follow-up; Kirurgi; Surgery; Kirurgi; kardiologi; Cardiology;

    Sammanfattning : In the present study the long-term survival and morbidity and the associated risk factors after aortic valve replacement (AVR) and after aortic balloon valvuloplasty were evaluated. In a cohort of 2,359 consecutive patients undergoing primary aortic valve replacement, the early mortality was 5.6%. 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.

  7. 5. 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
