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

    Författare :Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    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

  3. 2. Cardiovascular risk factors in aortic stenosis

    Författare :Johan Ljungberg; Stefan Söderberg; Bengt Johansson; Peter Nilsson; Umeå universitet; []
    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. Valvular aortic stenosis in children. Outcome, physical activity and health-related quality of life

    Författare :Cecilia Kjellberg Olofsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Valvular aortic stenosis; Critical aortic stenosis; Child; Neonate; Outcome; Surgical valvotomy; Physical activity; Health-related quality of life; Life satisfaction;

    Sammanfattning : Introduction: Isolated valvular aortic stenosis (VAS) accounts for 3–5% of congenital heart disease and presents with a wide spectrum of severity. Critical VAS in the neonate is the most severe form, fatal in the absence of treatment. Physical activity is essential for normal development and is a prerequisite for long-term cardiovascular health. LÄS MER

  5. 4. Heart Failure and Aortic Stenosis - Factors Influencing Prognosis and Development

    Författare :Silvana Kontogeorgos; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart failure; prognosis; predictive factors; aortic stenosis; obesity;

    Sammanfattning : Background: An ageing population increases the prevalence of heart failure (HF) and aortic stenosis (AS). Several studies have investigated prognosis and predictors of HF with preserved ejection fraction (HFpEF) compared to heart failure with reduced ejection frac-tion (HFrEF), with inconsistent results.

  7. 5. Clinical Outcomes of Transcatheter Aortic Valve Implantation (TAVI)

    Författare :Konrad Nilsson; Stefan James; Christina Christersson; Giovanna Sarno; Henrik Schirmer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcatheter aortic valve implantation; aortic stenosis; clinical outcomes; risk prediction; geographical differences; coronary artery disease; Cardiology; Kardiologi;

    Sammanfattning : Aortic stenosis (AS) is the most common valvular heart disease and most prevalent in the elderly. In the latest decades, a new method for replacement of the aortic valve: transcatheter aortic valve implantation (TAVI) has been introduced. LÄS MER
