  1. 1. Mechanical Circulatory Support in Left Ventricular Heart Failure

    Författare :Petter Schiller; Laila Hellgren; Anders Jönsson; Göran Dellgren; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical Circulatory Support; Left Ventricular Heart Failure; Left Ventricular Assist Device; Extracorporeal Membrane Oxygenation; ECMO; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Short-term mechanical circulatory support (MCS) with ventricular assist devices or veno-arterial extracorporeal membrane oxygenation (VA ECMO) has become the standard treatment in patients with cardiogenic shock unresponsive to pharmacological treatment. However, the haemodynamic effects of these devices are not yet fully described, nor are their effects on ventricular function and myocardial recovery. LÄS MER

  2. 2. Management of patients treated with left ventricular assist devices : A clinical and experimental study

    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postcardiotomy heart failure; perioperative monitoring; coronary artery bypass; heart-assist devices; heart failure; congestive; ventricular dysfunction; Thoracic surgery; Thoraxkirurgi;

    Sammanfattning : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. LÄS MER

  3. 3. Acoustic and afterload evaluation of left ventricular assist devices

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Afterload; Electronic stethoscope; Flow; HeartMate II; HeartMate 3; iOS-devices; Sound Analysis;

    Sammanfattning : Background: Heart Failure is a serious condition with consequences not only for the individual patient but also for the society with a 5-year mortality rate of 45-60%, and a substantial economic burden. The estimated prevalence in Sweden is 2.2% and the age adjusted prevalence increases with higher age. LÄS MER

  4. 4. Treatment of Right Ventricular Failure through Partial Volume Exclusion : An Experimental Study

    Författare :Per Vikholm; Laila Hellgren; Lund Lars; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Right Heart Failure; Left Ventricular Assist Device; Glenn shunt; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Implantation of a left ventricular assist device (LVAD) is a potential treatment in terminal heart failure. Right ventricular (RV) failure is a severe complication in these patients and sometimes requires additional placement of a right ventricular assist device (RVAD). LÄS MER

  5. 5. A minimally invasive axial blood flow pump : an experimental and clinical study

    Författare :Urban Lönn; Howard Frazier; Linköpings universitet; []
    Nyckelord :Axial blood flow pump; Hemopump; LVAD; Beating heart CABG; MEDICINE; MEDICIN;

    Sammanfattning : The first aim of this thesis was to evaluate a new minimally invasive axial blood flow pump for treatment of patients needing circulatory support after open heart surgery. This system, the Hemopump temporary cardiac assist device, is a very small catheter mounted intracorporeal pump, which is introduced transvalvularly into the left ventricle. LÄS MER
