1. 1. Hope Rites : An Ethnographic Study of Mechanical Help-Heart Implantation Treatment

   Författare :Haris Agic; Marja-Liisa Honkasalo; Lars-Christer Hydén; Robert Desjarlais; Linköpings universitet; []
   Nyckelord :Medical technology; uncertainty; ritual; emotions; ethnography; liminality; end-stage heart failure; mechanical help-heart; progress; hope.; Medicinsk teknologi; ovisshet; ritual; emotioner; etnografi; liminalitet; akut svår hjärtsvikt; mekaniskt hjälphjärta; framsteg; hopp.;

   Sammanfattning : This thesis is about cultural aspects of advanced medical technology for treating end-stage heart failure. New medical technologies like mechanical help-hearts save lives, but they also bring new uncertainties, risks, and challenges. LÄS MER

3. 2. Mechanical and histological disturbances in advanced heart failure and cardiac transplantation

   Författare :Matteo Cameli; Michael Henein; Guy Lloyd; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Advanced heart failure; heart transplantation; speckle tracking echocardiography; left ventricular function; right ventricular function; left ventricular fibrosis; left ventricular filling pressure; atrial strain; kariologi; Cariology;

   Sammanfattning : The general purpose of this thesis is to establish capability and accuracy of speckle tracking echocardiography (STE) in assessing left atrial (LA), left ventricular (LV) and right ventricular (RV) function and their correlation with myocardial fibrosis, filling pressure and clinical outcomes in advanced heart failure (HF) patients before and after heart transplantation (HT).I demonstrated that HT recipients had impaired LV twist dynamics in the form of reduced rotation twist angle and untwist rate but time to peak twist was not different from the age matched controls and other cardiac surgical patients.

4. 3. Afterload system design for functional donor heart assessment

   Författare :Harry Pigot; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physiological modelling; cardiac afterload; heart assessment; working heart; simulation; control of physiological and clinical variables;

   Sammanfattning : Heart transplantation is a life-saving procedure for patients with end-stage heart failure. However, conservative acceptance criteria result in most donated hearts being discarded. Enabling clinicians to assess heart function after organ procurement can pave the way for the safe use of hearts that are currently rejected. LÄS MER

5. 4. Echocardiographic assessment of ventricular size and function in heart transplant patients

   Författare :Annika Ingvarsson; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart Transplantation; Echocardiography; Speckle tracking; Left ventricular assist device;

   Sammanfattning : AbstractThe overall aims of this thesis were to use echocardiography to non-invasively, delineate early structural andfunctional changes following orthotopic heart transplantation (OHT), and to define reference values in the contextof gender and bridging with mechanical circulatory support.Several factors might affect myocardial function in OHT patients rendering the use of normal values fortransthoracic echocardiography derived from healthy subjects unsatisfactory.

7. 5. Cardiovascular risk factors in aortic stenosis

   Författare :Johan Ljungberg; Stefan Söderberg; Bengt Johansson; Peter Nilsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Valvular heart disease; aortic stenosis; bicuspid aortic valve; cardiovascular risk factors; hypertension; diabetes mellitus; smoking; hypercholesterolemia; obesity; shrunken pore; renal failure; Epidemiology; epidemiologi; Cardiology; kardiologi;

   Sammanfattning : Introduction: Aortic stenosis (AS) is the most common hemodynamic significant valvular heart disease and affects about 2% of the population. The incidence increases with age. When symptoms of the stenotic aortic valve disease eventually occur the 2-year mortality exceeds 50%. LÄS MER
