1. 11. Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta

   Författare :Adel BinJabr; Vaskulära sjukdomar - kliniska studier; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chimney stent graft; chimney graft; chimney graft technique; snorkel technique; endovascular aortic repair; thoracic endovascular aortic repair; endoleak; patency; rupture; urgent; stent-graft; stent; graft; aorta; computed tomography; ultrasound; stenosis; EVAR; TEVAR; CTA; MRI; AAA; TAAA; supraaortic; visceral; aneurysm; dissection; mycotic infection; stent-graft infection; follow-up; endovascular complication; sandwich technique; periscope graft; periscope graft technique.;

   Sammanfattning : Introduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. LÄS MER

3. 12. Secundum atrial septal defect in the adult. Clinical, haemodynamic and electrophysiological aspects

   Författare :Ulf Thilén; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; clinical outcome; atrial fibrillation; Atrial septal defect; atrial conduction; remodelling.;

   Sammanfattning : Atrial septal defect (ASD) is the most common congenital heart malformation diagnosed in adult life. In this thesis important clinical, haemodynamic and electrophysiological aspects of ASD in the adult are explored. LÄS MER

4. 13. Automated Assessment of Blood Flow in the Cardiovascular System Using 4D Flow MRI

   Författare :Mariana Bustamante; Tino Ebbers; Carljohan Carlhäll; Petter Dyverfeldt; Michael Markl; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; 4D Flow MRI; Image Analysis; Segmentation;

   Sammanfattning : Medical image analysis focuses on the extraction of meaningful information from medical images in order to facilitate clinical assessment, diagnostics and treatment. Image processing techniques have gradually become an essential part of the modern health care system, a consequence of the continuous technological improvements and the availability of a variety of medical imaging techniques.

5. 14. Cardiac Long-Axis Function. Experimental and Clinical Aspects

   Författare :Jonathan Berg; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; acute myocardal infarct; magnetic resonance imaging MRI ; pressure-volume loops; hypothermia; atrioventricular plane displacement; global longitudinal strain; Survival analyses;

   Sammanfattning : This thesis includes both experimental and clinical projects. The experimental studies investigate pathophysiological aspects of ventricular longitudinal function and therapeutic hypothermia during acute myocardial infarction (AMI). LÄS MER

7. 15. Pump Physiology in the Remodeled Heart

   Författare :Björn Östenson; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac magnetic resonance; cardiac remodeling; exercise imaging; exercise physiology; regional contributions to stroke volume; feature-tracking strain; atrioventricular plane displacement; atrioventricular coupling; ventricular-arterial coupling; clinical physiology;

   Sammanfattning : This thesis aimed to increase the understanding of pump physiology in the remodeled heart compared to normal pump physiology.Study I was a cross-sectional observatory study investigating the regional contributions to stroke volume in patients with heart failure prior to cardiac resynchronization therapy (CRT) and tested the hypothesis that this characterization of pumping could predict CRT response.
