  1. 1. Atrial fibrillation in cardiac surgery

    University dissertation from Örebro : Örebro universitet

    Author : Anders Ahlsson; Anders Englund; Johan Brandt; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Inflammation; CABG surgery; Survival analysis; Follow-up studies; Ablation; Microwave; Transmurality; Atrial function; Tissue velocity echocardiography; MEDICINE Surgery Surgical research Thoracic surgery; MEDICIN Kirurgi Kirurgisk forskning Thoraxkirurgi; Kirurgi; särskilt thoraxkirurgi; Surgery esp. Thoracic and Cardivascular Surgery;

    Abstract : Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. In cardiac surgery, one-third of the patients experience episodes of AF during the first postoperative days (postoperative AF), and patients with preoperative AF (concomitant AF) can be offered ablation procedures in conjunction with surgery, in order to restore ordinary sinus rhythm (SR).

  2. 2. Risk stratification in cardiac surgery: Algorithms and applications

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Johan Nilsson; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; traumatology; Kardiovaskulära systemet; Cardiovascular system; Cardiac surgery; Statistics; Artificial neural networks; Resource utilization; Mortality; Risk factors; Kirurgi; ortopedi; traumatologi;

    Abstract : The aims of this research was to compare different risk score algorithms with regard to their validity to predict 30-day and one-year mortality after open-heart surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural networks (ANNs) to select and rank the most important risk factors for operative mortality in open-heart surgery. Preoperative evaluation of the surgical risk is an important component in cardiac surgery. READ MORE

  3. 3. Metabolic intervention during blood cardioplegia. Clinical studies in coronary surgery and heart transplantation

    University dissertation from Göteborg

    Author : Ulf Kjellman; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac surgery; heart transplantation; oxygen extraction; substrate metabolism; predictors of ischemic injuries; a - ketoglutarate; insulin;

    Abstract : Myocardial ischemia and injury (infarction) during open heart surgery and heart transplantation is a problem in spite of the fact that it is a safe procedure today. The myocardial substrate metabolism is well investigated before and after the cardioplegic period but little knowledge exists about the myocardial metabolic changes during cardioplegia. READ MORE

  4. 4. 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

    University dissertation from Göteborg

    Author : Charles Kennergren; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Management of bile duct calculi : a study with special reference to long-term outcome

    University dissertation from Lars-Erik Hammarström, M.D., Department of Surgery, University of Lund, S-221 85 Lund, Sweden

    Author : Lars-Erik Hammarström; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic yield; preoperative infusion cholangiography; long-term follow-up; endoscopic sphincterotomy; open choledocholithotomy; remote cholecystectomy; Common bile duct stone; gallbladder in situ; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : Open surgical versus endoscopic treatment of CBD stones in 80 elderly not cholecystectomized patients revealed a similar efficacy of stone clearance and early major complication rates, as well as total complication rates and hospitalization time in the two groups during 5 to 9 years follow-up. However, more patients in the endoscopically treated group died from heart disease, suggesting surgery to become the favoured treatment in this selected category of patients. READ MORE
