1. 1. Prosthetic aortic heart valves

   Författare :Natalie Glaser; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Aortic valve replacement (AVR) can be performed with different types of valve prostheses. There is no perfect aortic valve prosthesis, and the prosthetic choice for each patient requires careful consideration. This thesis evaluates mortality, morbidity, and prosthetic valve function after AVR with different aortic valve prostheses. LÄS MER

3. 2. Aortic aneurysms and dissections. A clinical follow-up after surgery

   Författare :Vincenzo Lepore; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic aneurysm; aortic dissection; composite-graft; aortic arch replacement; aortic endoluminal stent-graft; Marfan syndrome; MRI.;

   Sammanfattning : ABSTRACTThe purpose of this study was to report on the results after aortic surgery on thoracic aneurysms and dissections and to study the feasibility of magnetic resonance imaging (MRI) in the follow-up after aortic surgery. In this thesis, 203 patients ungergoing surgery on the thoracic aorta between 1977 and 2000 are included. LÄS MER

4. 3. Epidemiological studies of bioprosthetic aortic valves

   Författare :Michael Dismorr; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: The use of bioprosthetic valves is common and offers a prosthetic option that does not require anti-coagulant therapy, but with shorter valve longevity compared to mechanical prostheses. Valve model selection might influence the long-term performance of the prosthesis. LÄS MER

5. 4. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

   Författare :Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

   Sammanfattning : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. LÄS MER

7. 5. Chlamydia pneumoniae in Aortic Valve Sclerosis and Thoracic Aortic Disease : Aspects of Pathogenesis and Therapy

   Författare :Christina Nyström-Rosander; Kenneth Persson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Chlamydia pneumoniae; aortic valve sclerosis; trace elements; thoracic aorta; antibiotics; Polymerase Chain Reaction PCR ; electron microscopy EM ; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar; infektionssjukdomar; Infectious Diseases;

   Sammanfattning : The obligate intracellular bacterium Chlamydia pneumoniae (Cp), a common human pathogen, has been associated with atherosclerotic cardiovascular disease. The aetiology of non-rheumatic aortic valve sclerosis has, however, not been clarified. LÄS MER
