2. 1. Atrial fibrillation in cardiac surgery

   Author : Anders Ahlsson; Anders Englund; Johan Brandt; Örebro universitet; []
   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; Thoracic surgery; 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).

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

   Author : Johan Nilsson; Thoraxkirurgi; []
   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

5. 3. Atrial fibrillation after cardiac surgery : an analysis of risk factors, mechanisms, and survival effects

   Author : Giovanni Mariscalco; Bengt Åberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; adult; cardiac surgery; coronary artery bypass grafting; valvular surgery; cardiopulmonary bypass; mortalilty; histology; catecholamines; embolism; Surgery; Kirurgi;

   Abstract : Background: Despite the recent improvements in surgical techniques and postoperative patient care, atrial fibrillation (AF) remains the most frequent complication after cardiac surgery. Although postoperative AF is often regarded as a benign clinical condition, this arrhythmia has significant adverse effects on patient recovery and postoperative survival. READ MORE

6. 4. S100B and Cardiac Surgery

   Author : Henrik Bjursten; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; S100-B; S100B; S100beta; brain damage; cardiac surgery; CABG; renal function; autotransfusion; Cardiovascular system; serum marker; Kardiovaskulära systemet;

   Abstract : The brain-derived protein S100B is a 21 Kda dimerand have been used as a serum marker for brain damage of different etiology. The feasability of protein S100B as serum marker for brain damage after cardiac surgery was studied in this thesis. One unexpected finding was made, which changed the basis for interpration of S100B levels. READ MORE

7. 5. Vacuum-assisted closure in cardiac surgery - clinical outcome and vascular effects

   Author : Johan Sjögren; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Kardiovaskulära systemet; Cardiovascular system; Infektioner; Infections; endothelium; vascular; central hemodynamics; risk factors; long-term survival; mortality; wound closure; cardiac surgery; vacuum-assisted closure; poststernotomy mediastinitis; traumatology; Kirurgi; ortopedi; traumatologi;

   Abstract : The aim of this research was to clinically and experimentally evaluate the use of vacuum-assisted closure in poststernotomy mediastinitis after cardiac surgery. Vacuum-assisted closure (VAC) is a new wound-healing therapy based on the application of a local negative pressure to the wound. READ MORE
