  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. 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

  4. 3. 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

  5. 4. On the acquisition, analysis and display of echocardiographic image sequences

    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;

    Sammanfattning : .... LÄS MER

  7. 5. Surgical Ablation of Atrial Fibrillation with Cryo and Radiofrequency Concomitant to Mitral Valve Surgery : Clinical, Biochemical and Echocardiography Outcomes

    Författare :Gabriella Boano; Farkas Vánky; Meriam Åström Aneq; Lena Jideus; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Mitral valve surgery; Surgical ablation; Cox-Maze IV; Left atrium remodelling; 3D echocardiography;

    Sammanfattning : Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. In cardiac surgery, the negative influence of AF on short- and long-term outcomes has made concomitant ablation procedures more common. LÄS MER
