1. Surgical treatment in chronic aortic regurgitation : Timing, results, prognosis and left ventricular function
Sammanfattning : 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. LÄS MER
2. Cardiovascular modelling and ultrasound heart flow quantification : aortic flow and mitral regurgitation
Sammanfattning : 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. LÄS MER
3. Aortic valvular flow : a clinical and experimental doppler echocardiographic study
Sammanfattning : 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. LÄS MER
4. Cardiovascular risk factors in aortic stenosis
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
5. Survival and functional recovery following valve replacement in patients with severe aortic stenosis
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
