1. 1. 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. 2. Cardiovascular risk factors in aortic stenosis

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Valvular heart disease; aortic stenosis; bicuspid aortic valve; cardiovascular risk factors; hypertension; diabetes mellitus; smoking; hypercholesterolemia; obesity; shrunken pore; renal failure; Epidemiology; epidemiologi; Cardiology; kardiologi;

   Sammanfattning : Introduction: Aortic stenosis (AS) is the most common hemodynamic significant valvular heart disease and affects about 2% of the population. The incidence increases with age. When symptoms of the stenotic aortic valve disease eventually occur the 2-year mortality exceeds 50%. LÄS MER

4. 3. Effect of valve replacement for aortic stenosis on ventricular function

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; aortic valve replacement; echocardiography; speckle tracking; exercise echocardiography; ventricular function; septal radial motion; twist; displacement; strain; strain rate;

   Sammanfattning : Background：Aortic stenosis (AS) is the commonest valve disease in the West. Aortic valve replacement (AVR) remains the only available management for AS and results in improved symptoms and recovery of ventricular functions. LÄS MER

5. 4. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

   Författare :Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

   Sammanfattning : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. LÄS MER

7. 5. Hope and life-struggle : patients' experiences with Transcatheter Aortic Valve Implantation

   Sammanfattning : The overall aim of this thesis is to explore experiences and self-reported outcomes from Transcatheter Aortic Valve Implantation, TAVI, among people with severe aortic stenosis. The thesis includes four studies. Study I-II are based on interviews performed the day before TAVI and Qualitative Concept Analysis was used for analysis. LÄS MER
