  1. 1. Strain echocardiography in the critically ill patient Studies in patients with septic shock and subarachnoid haemorrhage

    University dissertation from Göteborgs universitet

    Author : Keti Dalla; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Strain echocardiography in ICU patients; Left ventricle; Right ventricle; Septic shock; Subarachnoid haemorrhage; Norepinephrine;

    Abstract : In this thesis, strain echocardiography by two-dimensional speckle tracking imaging (2D-STI), was used for the evaluation of left ventricular (LV) and right ventricular (RV) function in critically ill patients with septic shock and subarachnoid haemorrhage. The aims were to: 1) investigate the value of strain echocardiography for the early detection of LV and RV dysfunction not diagnosed with conventional echocardiography in severe sepsis and septic shock, 2) to study the effects of norepinephrine on RV systolic function and pulmonary haemodynamics in patients with norepinephrine-dependent septic shock 3) evaluate the use of strain echocardiography for detection of myocardial injury in patients with subarachnoid haemorrhage (SAH) and 4) study the impact of general anaesthesia and positive pressure ventilation (PPV) on RV and LV myocardial longitudinal strain.

  3. 3. The effect of pressure afterload due to aortic coarctation on left ventricular function in children

    University dissertation from Umeå : Umeå Universitet

    Author : Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coarctation of the aorta; congenital aortic stenosis; left ventricle; myocardial deformation imaging; speckle tracking echocardiography; longitudinal strain; aorto-septal angle; children; Cardiology; kardiologi;

    Abstract : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. READ MORE

  4. 4. Left atrial function in health and disease

    University dissertation from Umeå : Umeå university

    Author : Mark Henein; Per Lindqvist; Stellan Mörner; Reidar Winter; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrium; Doppler echocardiography; atrial interaction; atrial pressure;

    Abstract : The Objectives of this thesis are:1) To study possible atrial interaction in patients with right and left ventricular outflow tract obstruction due to significant pulmonary (PS) and aortic valve stenosis (AS), respectively.2) To assess left atrial (LA) intrinsic myocardial function and its relationship to indirect measures of left ventricular (LV) filling pressures in patients with paroxysmal atrial fibrillation (PAF).

  5. 5. Insights into left atrial response to pressure and volume overload

    University dissertation from Umeå : University of Umeå

    Author : Matteo Lisi; Michael Henein; Sergio Mondillo; Lars-Åke Lars; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keywords Mitral regurgitation; aortic stenosis; speckle tracking echocardiography; heart transplantation; left atrial strain; left ventricualr function; right ventricular function; myocardial fibrosis;

    Abstract : The general purpose of this thesis is to establish the ability of Speckle Tracking Echocardiography (STE) in assessing left atrial (LA) response to pressure and volume overload respectively in aortic stenosis (AS) and mitral regurgitation (MR), and to evaluate its accuracy in predicting LA and right ventricular (RV) fibrosis in patients with end-stage heart failure (HF) undergoing heart transplantation (HTx).I demonstrated that assessment of left ventricular (LV) long axis systolic velocity and amplitude of excursion is more sensitive than simple determination of ejection fraction (EF) for revealing the beneficial impact of MR surgery on overall LV systolic performance.
