  2. 11. Quantitative echocardiographic methods for patients with acute coronary syndrome

    Author : Carl Westholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Tissue Doppler;

    Abstract : Background: The aim of this thesis was to evaluate two diagnostic and two prognostic quantitative echocardiographic methods for patients with acute coronary syndrome (ACS). Methods:
Velocity tracking (VeT) presents the longitudinal tissue Doppler velocities of the left ventricle (LV) as a bull’s eye plot giving an easy three dimensional understanding of both the global and regional function of the LV in regard to longitudinal velocities, systolic as well as diastolic.

  4. 12. Cardiac Performance, Ventricular-Vascular Interaction and Functional Alterations in Rheumatic Mitral Stenosis : A descriptive study employing novel hemodynamic and echocardiographic modalities

    Author : Ashwin Venkateshvaran; Lars-Åke Brodin; Per Lindquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tillämpad medicinsk teknik; Applied Medical Technology;

    Abstract : The assessment of LV performance poses significant challenges in the setting of rheumatic mitral stenosis (MS) owing to an inherently load-altered state. A detailed characterization of arterial-ventricular coupling between subjects with isolated post-capillary pulmonary hypertension (Ipc-PH) and combined pre- and post-capillary pulmonary hypertension (Cpc-PH) has not been described.

  5. 13. The heart in the critically ill patient- an echocardiographic study

    Author : Lill Bergenzaun; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; shock; left ventricular function; biomarkers; and outcome;

    Abstract : The thesis describes aspects of left ventricular systolic and diastolic function examined with echocardiography in patients with systemic inflammation and shock. Background: Myocardial depression is a well-known complication in critically ill patients with shock. READ MORE

  7. 15. 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.
