  2. 16. Ventricular rotation and the rotation axis : a new concept in cardiac function

    Author : Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

    Abstract : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. READ MORE

  4. 17. Novel approaches using electrocardiographic imaging for early detection of ARVC in patients and relatives and symptoms preceding sudden death

    Author : Varvara Kommata; Carina Blomström-Lundqvist; Elena Sciaraffia; Domenico Corrado; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arrhythmogenic Right Ventricular Cardiomyopathy; diagnosis; gene carriers; body surface mapping; electrocardiographic imaging; sudden cardiac death; Cardiology; Kardiologi; Cardiology; Kardiologi;

    Abstract : Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is an inherited disease of the myocardium, predominantly affecting the right ventricle (RV). Arrhythmias are common among patients with the disease and Sudden Cardiac Death (SCD) can occur even in early stages. READ MORE

  5. 18. Continuous ambulatory hemodynamic monitoring with an implantable system : the feasibility of a new technique

    Author : Åke Ohlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : heartfailure; hemodynamic monitoring; implantable; oxygen saturation; pressure; ambulatory; right ventricle; dPdt; long-term; sensor; cardiac output.;

    Abstract : Patients with chronic heart failure constitute an increasingly large group. Despite recent therapeutic improvements, these patients have a poor prognosis. READ MORE

  6. 19. Left ventricular filling during coronary artery bypass grafting

    Author : Sten Samuelsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Heart: surgery; coronary artery revascularization; ventricle; mitral valve Cardiopulmonary bypass Cardiac output Thermodilution Echocardiography: transesophageal; two-dimensional; Doppler Radionuclide ventriculographySten Samue;

    Abstract : Left ventricular (LV) filling, determination of preload, right ventricular end-diastolic volumes, volume contributions during early (E) and atrial (A) phases of LV filling and mitral valve opening areas were studied in 75 patients scheduled for elective coronary artery bypass grafting (CABG). The purposes of the study were: (1) To evaluate changes in LV filling judged as peak velocity E/A ratios determined by Doppler transesophageal echocardiography during and in the early phase after CABG.

  7. 20. Functional and morphological MR studies in congenital cardiovascular malformations

    Author : Catarina Holmqvist; Lund Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; Contrast-enhanced MR angiography.; Coarctation; Intra-cardiac shunts; Conduits; Tetralogy of Fallot; Function; Flow; MR velocity mapping; Infants; Children; Magnetic Resonance Imaging; Angiocardiography; Heart; Congenital heart defects; medical instrumentation; tomography; radiology; Clinical physics;

    Abstract : The aim of this study was to evaluate new MR techniques permitting qualitative and quantitative analysis of cardiac function and measurement of velocity and flow, and later on contrast-enhanced MR angiography, techniques largely unexplored in children with CHD. Infants with tetralogy of Fallot and pulmonary atresia with ventricular septal defect were examined pre-operatively. READ MORE
