  2. 1. Surgical treatment in chronic aortic regurgitation : Timing, results, prognosis and left ventricular function

    Author : Éva Tamás; Christian Olin; Eva Nylander; Mats Broqvist; Dan Lindblom; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic regurgitation; left ventricular function; exercise; physical capacity; echocardiography; Thoracic surgery; Thoraxkirurgi;

    Abstract : Chronic aortic regurgitation (AR) of varying degree affects 13% of men and 8.5% of women. In persons with severe AR, the expected length of life and its quality are influenced. READ MORE

  4. 2. Cardiovascular modelling and ultrasound heart flow quantification : aortic flow and mitral regurgitation

    Author : Lars E. J. Eidenvall; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The primary objective of this thesis was to model and simulate aortic flow and mitral regurgitation and to improve quantitative ultrasound measurements. The tools used were; theoretical analysis, computer simulation, model experiments, image analysis and clinical evaluation. READ MORE

  5. 3. Aortic valvular flow : a clinical and experimental doppler echocardiographic study

    Author : Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. READ MORE

  6. 4. Cardiovascular risk factors in aortic stenosis

    Author : Johan Ljungberg; Stefan Söderberg; Bengt Johansson; Peter Nilsson; Umeå universitet; []
    Keywords : 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;

    Abstract : 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%. READ MORE

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

    Author : Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
