  1. 1. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography

    Författare :Kambiz Shahgaldi; Lars-Åke Brodin; Michael Haney; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Three-dimensional echocardiography; heart chambers; flow-volume loop; left ventricular ejection fraction; visualization; left ventricular stroke volume; left ventricular outflow tract; and single-heartbeat; Medical technology; Medicinsk teknik;

    Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER

  3. 2. New insights in the assessment of right ventricular function : an echocardiographic study

    Författare :Avin Calcutteea; Michael Y Henein; Per Lindqvist; Jan Engvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; echocardiography; right ventricle; ischaemic heart disease; pulmonary hypertension; aortic stenosis; aortic valve replacement; three dimensional echocardiography; speckle tracking echocardiography; Cardiology; kardiologi;

    Sammanfattning : Background:  The right ventricle (RV) is multi-compartmental in orientation with a complex structural geometry. However, assessment of this part of the heart has remained an elusive clinical challenge. LÄS MER

  4. 3. Cardiac morphology and dynamics in Swedish elite orienteers : Evaluation of the right and left ventricle by two-dimensional and doppler echocardiography

    Författare :Egil Henriksen; Uppsala universitet; []
    Nyckelord :Medical sciences; Echocardiography; sudden unexpected death in young orienteers; right and left ventricular measurements; Doppler echocardiography in athletes; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Background. Between 1979 and 1992, 16 (15 males and 1 female) sudden unexpected cardiac deaths(SUCD) were reported in Swedish orienteers. Compared with previous reports in young athletes there was a 10- to 100-fold increase in the sudden death rate in young male elite orienteers during this period. The mean age was 25 years (range 18-32 years). LÄS MER

    Författare :Tomas Gustavsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; motion detection; graphical modelling; ultrasonic imaging; wall motion analysis; three-dimensional reconstruction; image sequence analysis; spatio-temporal filtering; Echocardiography; left ventricular function; time-varying image analysis;

  7. 5. Three-dimensional assessment of cardiac function; When right is wrong

    Författare :Ellen Ostenfeld; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Key words Three-dimensional echocardiography; cardiac magnetic resonance imaging; cardiac function; volumes; atria; ventricles; pulmonary hypertension; right heart catheterization; right ventricular pressure load.;

    Sammanfattning : Assessment of the right side of the heart is important in patients with heart disease; especially in patient with elevated pressure in the lung circulation. Decreased right ventricular function and elevated pressure in the right atrium are of poor prognostic value. LÄS MER
