  1. 1. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

    Author : Martin Fredholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; strain echocardiography; right heart catheterization; cardiac surgery; heart failure; levosimendan; milrinone; left ventricular function; right ventricular function; systole; diastole; preload; afterload; pacing; longitudinal function; ventricular dimensions; ventricular interdependence;

    Abstract : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.

  2. 2. Arrhythmogenic right ventricular cardiomyopathy : Is it right?

    Author : Meriam Åström Aneq; Eva Nylander; Jan Engvall; Maria Eriksson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart disease, where sudden cardiac death in young seemingly healthy persons may be the first symptom. There is a need for more sensitive and accurate diagnostic methods to detect signs of disease, at an early stage and in relatives of affected individuals. READ MORE

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

    Author : Ellen Ostenfeld; Lund Klinisk fysiologi; []
    Keywords : 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.;

    Abstract : 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. READ MORE

  4. 4. Echocardiographic assessment of ventricular size and function in heart transplant patients

    Author : Annika Ingvarsson; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart Transplantation; Echocardiography; Speckle tracking; Left ventricular assist device;

    Abstract : AbstractThe overall aims of this thesis were to use echocardiography to non-invasively, delineate early structural andfunctional changes following orthotopic heart transplantation (OHT), and to define reference values in the contextof gender and bridging with mechanical circulatory support.Several factors might affect myocardial function in OHT patients rendering the use of normal values fortransthoracic echocardiography derived from healthy subjects unsatisfactory.

  5. 5. On the assessment of right ventricular function using cardiac magnetic resonance imaging and echocardiography

    Author : Stina Jorstig; Per Thunberg; Kent Emilsson; Mats Lidén; Micael Waldenborg; Einar Heiberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; right ventricle; stroke volume; ejection fraction; cardiac magnetic resonance; ehocardiography; Kirurgi; Surgery;

    Abstract : Transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) imaging are two commonly used imaging modalities for evaluating the size and function of the heart. There are advantages and disadvantages associated with both modalities when examining the right ventricle (RV). READ MORE
