  1. 6. Surgery for aortic stenosis : with special reference to myocardial metabolism, postoperative heart failure and long-term outcome

    Författare :Farkas Vánky; Rolf Svedjeholm; Dan Lindblom; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Aortic stenosis; Surgery; Postoperative heart failure; Long-term outcome; Metabolism; Medicine; Medicin;

    Sammanfattning : Postoperative heart failure (PHF) remains a major determinant of the outcome after cardiac surgery. However, characteristics of and risk factors for PHF after valve surgery have received little attention. LÄS MER

  3. 7. 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

  4. 8. Implications of myocardial dysfunction before and after aortic valve intervention

    Författare :Henrik Hultkvist; Farkas Vánky; Rolf Svedjeholm; Jonas Holm; Odd Bech-Hanssen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : BACKGROUNDPostoperative heart failure in the setting of aortic valve surgery results in poor long-term survival. We hypothesized that there could be a myocardial factor that is not addressed by risk scores currently available. We speculated that this myocardial factor could be diastolic dysfunction. LÄS MER

  5. 9. Cellular monitoring in open heart surgery. Monitoring of markers for ischemia, free amino acids, glucose and lactate in the myocardial interstitial fluid before, during and after cardiac surgery using microdialysis technique

    Författare :Charles Kennergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac surgery; myocardial ischemia; microdialysis; interstitial markers; ASAT; troponin-T; amino acids; glucose; lactate;

    Sammanfattning : Protection of the myocardium during open-heart surgery is a field of intense development. Numerous protocols have been proposed to minimize ischemia, since the beginning of open-heart surgery more than 40 years ago. LÄS MER

  7. 10. NT-proBNP as a marker of postoperative heart failure in adult cardiac surgery

    Författare :Huiqi Jiang; Rolf Svedjeholm; Yanqi Yang; Jonas Holm; Farkas Vanky; Johan Nilsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Postoperative heart failure (PHF) remains the major cause of mortality after cardiac surgery. Unfortunately, generally accepted diagnostic criteria for PHF are lacking. This may explain why the evidence for the efficacy and safety of current treatment of PHF with inotropes is insufficient. LÄS MER
