2. 1. 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

4. 2. Transcatheter Aortic Valve Implantation: Risk Assessment and Clinical Outcome

   Author : Malin Johansson; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Key words: Aortic stenosis; transcatheter aortic valve implantation; outcome; acute kidney injury;

   Abstract : Abstract Background: Transcatheter aortic valve implantation (TAVI) has emerged as a treatment for patients with aortic stenosis (AS) and high surgical risk. To date, reports of short- and mid-term survival have been favourable. The aim of this thesis was to evaluate early safety, risk assessment and late survival following TAVI. READ MORE

5. 3. Markers of hemodynamic state and heart failure as predictors for outcome in cardiac surgery : with special reference to mixed venous oxygen saturation and natriuretic peptides

   Author : Jonas Holm; Rolf Svedjeholm; Erik Håkanson; Farkas Vanky; Jan van der Linden; Linköpings universitet; []
   Keywords : ;

   Abstract : Postoperative heart failure or low cardiac output syndrome is the major cause for morbidity and mortality in cardiac surgery. Unfortunately commonly used methods to assess hemodynamic state and heart failure are not well documented with regard to outcome. READ MORE

6. 4. Vacuum-Assisted Closure Therapy after Cardiac Surgery. Sternal Stability, Cost of Care, Learning Curve and Hemodynamic Outcome

   Author : Arash Mokhtari; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health economics; Vacuum-assisted closure; Sternum; Mediastinitis; Deep sternal wound infection; Cardiac surgery; Wound healing; Hemodynamics; Wound closure;

   Abstract : Deep sternal wound infection (DSWI) following cardiothoracic surgery is a rare but potentially life-threatening complication with high morbidity and mortality. DSWI is associated with a significant increase in the length of hospital stay and the cost of hospitalization. The socioeconomic impact of DSWI is considerable. READ MORE

7. 5. Implications of myocardial dysfunction before and after aortic valve intervention

   Author : Henrik Hultkvist; Farkas Vánky; Rolf Svedjeholm; Jonas Holm; Odd Bech-Hanssen; Linköpings universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE
