  1. 6. 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

  3. 7. Cardiac Function and Aortic Valve Intervention : Echocardiographic Studies of Myocardial Recovery in Patients with Severe Aortic Valve Disease

    Författare :Lena Forsberg; Eva Nylander; Éva Tamás; Odd Bech-Hanssen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In patients with severe aortic valve disease, aortic valve intervention is performed when the risk for mortality or morbidity with conservative management is significantly increased. Left ventricular (LV) longitudinal motion decreases before conventional echocardiographic measures such as ejection fraction, are influenced in patients with severe aortic valve disease. LÄS MER

  4. 8. Valve-less diffuser micropumps

    Författare :Anders Olsson; KTH; []
    Nyckelord :;

    Sammanfattning : Today there is growing interest in research on microfluidicsystems, e.g., for chemical analysis systems and microdosagesystems. One of the basic components in microfluidic systems ismicropumps. LÄS MER

  5. 9. Signs of inflammation in different types of heart valve disease : The VOCIN study

    Författare :Lars Wallby; Lena Jonasson; Mats Broqvist; Mårten Rosenqvist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart valve dysfunction; heart valve disease; VOCIN study group; aortic valves; Gross valvular pathology; Cariology; Cariologi;

    Sammanfattning : Heart valve dysfunction is a relatively common condition in the population, whereas significant heart valve disease is more unusual. The cause of different types of heart valve disease depends on which valve is concerned. Rheumatic heart valve disease, has for a long time been considered to constitute a post-inflammatory condition. LÄS MER

  7. 10. Aortic valve surgery: Clinical studies after autograft, homograft and prosthetic valve replacement

    Författare :Obaid Aljassim; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic valve surgery; Ross operation; Homograft; Doppler-Catheter gradients;

    Sammanfattning : Aortic Valve Surgery Clinical studies after autograft, homograft and prosthetic valve replacement Obaid Aljassim, MD Department of Cardiovascular Surgery and Anaesthesia, Sahlgrenska University Hospital and University of Gothenburg Introduction and Aims: Aortic valve disease in symptomatic adult patients often requires surgery. Several alternatives are available: repair, mechanical and biological prostheses, homograft and the Ross procedure. LÄS MER
