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

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

    Sammanfattning : 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). LÄS MER

  3. 17. Echocardiographic measurements at Takotsubo cardiomyopathy : transient left ventricular dysfunction

    Författare :Micael Waldenborg; Kent Emilsson; Ole Fröbert; Per Lindqvist; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; takotsubo; annulus motion; cardiac autonomic function; broken heart; diastolic; ventricular mass; concentric wall motion; Medicine; Medicin; Biomedicin; Biomedicine;

    Sammanfattning : Takotsubo cardiomyopathy (TTC) is a disease characterized by transient left ventricular (LV) dysfunction and typical wall motion abnormalities in apical parts, without obvious signs of coronary influence. Due to its elusive natural cause and the lack of clarified pathology, further studies are needed. LÄS MER

  4. 18. Transoesophageal and transthoracic recordings of mitral annulus motion

    Författare :Bo Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Left ventricular function; echocardiography; M-mode; tissue Doppler; mitral annulus systolic and diastolic velocities;

    Sammanfattning : Maximal systolic and diastolic velocities recorded from four sites of the mitral annulus motion (MAM) reflect left ventricular (LV) performance. This thesis focus on factors influencing M-mode derived velocities in healthy children and adults and reference values are proposed. LÄS MER

  5. 19. Assessment of Left Ventricular Dysfunction and Remodelling by Determination of Atrioventricular Plane Displacement and Simplified Echocardiography

    Författare :Ronnie Willenheimer; Kardiologiska klinikens forskargrupp; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; simplified echocardiography; atrioventricular plane displacement; diagnosis; screening; heart failure; prognostication; latent heart failure; left ventricular dysfunction; Kardiovaskulära systemet;

    Sammanfattning : Heart failure is a common disease characterised by poor prognosis and frequent hospitalisations, constituting a major economic burden to society. Mortality and morbidity can be reduced by optimal treatment, requiring objective evaluation of cardiac function and anatomy. LÄS MER

  7. 20. Mitral annulus motion in left ventricular pumping

    Författare :Kent Emilsson; Peter Carlens; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiology; Kardiologi;

    Sammanfattning : This thesis focus on the role of the mitral annulus motion (MAM) versus outer contour changes in the short axis, in left ventricular (LV) pumping. The influence of atrial contraction on LV dimensions and volumes and the relation between MAM and ejection fraction (EF) in sinus rhythm and in atrial fibrillation was also studied. LÄS MER
