1. Implications of myocardial dysfunction before and after aortic valve intervention
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

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

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

4. Cardiovascular risk factors in aortic stenosis
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

5. NT-proBNP as a marker of postoperative heart failure in adult cardiac surgery
Abstract : Postoperative heart failure (PHF) remains the major cause of mortality after cardiac surgery. Unfortunately, generally accepted diagnostic criteria for PHF are lacking. This may explain why the evidence for the efficacy and safety of current treatment of PHF with inotropes is insufficient. READ MORE
