  2. 21. Atrial fibrillation – on its trigger mechanisms, risks and consequences

    Author : Dritan Poci; Göteborgs universitet; []
    Keywords : acute coronary syndromes; atrial fibrillation; AV junctional ablation; CHADS2 score; electrical cardioversion; mortality; stroke; trigger mechanisms;

    Abstract : Background: Atrial fibrillation (AF) frequently impairs quality of life, but in long-term it is associated with an increased morbidity and mortality. Persistent AF may cause changes in the sinus node function, and if converted to sinus rhythm (SR), there is a substantial risk of recurrence of AF. READ MORE

  4. 22. Evaluation of New Non-Pharmacological Therapies for Symptomatic Atrial Fibrillation : With Special Emphasis on the Maze Procedure

    Author : Stefan Lönnerholm; Lennart Bergfeldt; Uppsala universitet; []
    Keywords : Medical sciences; Atrial fibrillation; Maze procedure; pacing; quality of life; förmaksflimmer; MEDICIN OCH VÅRD; Maze kirurgi; livskvalitet; MEDICINE; MEDICIN; kardiologi; Cardiology;

    Abstract : Atrial fibrillation is a common disease. With pharmacological therapy most patients with atrial fibrillation have moderate or little symptoms, but a number of patients have severely symptomatic disease. This study evaluates two new non-pharmacological therapies for atrial fibrillation, the Maze procedure and atrial overdrive pacing. READ MORE

  5. 23. 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

  6. 24. Infarct size and myocardial function : A methodological study

    Author : Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. READ MORE

  7. 25. Fetal Cardiac Function and Venous Circulation - Experiences with Velocity Vector Imaging

    Author : Charlotte Dahlbäck; Urogynekologi och reproduktionsfarmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pregnancy; fetus; strain; speckle tracking; cardiac function; umbilical vein; venous; ductus venosus; Doppler;

    Abstract : Placental dysfunction resulting in intrauterine growth restriction (IUGR) is a common complication of pregnany and severe IUGR, with ensuing fetal hypoxia is an important cause of perinatal mortality and morbidity. Doppler studies of fetal and maternal vessels are routinely used for fetal surveillance and alterations in fetal venous blood flow has been demonstrated as a late sign of fetal compromise. READ MORE
