2. 1. Thoracic Aortic Surgery : Epidemiology, Outcomes, and Prevention of Cerebral Complications

   Author : Christian Olsson; Stefan Thelin; Jan van der Linden; Uppsala universitet; []
   Keywords : Surgery; Aorta; Thoracic; Aortic aneurysms; Aortic disease; Cardiovascular surgical procedures; Epidemiology; Registries; Treatment outcome; Survival analysis; Cerebral infarction; Near-infrared spectroscopy; Quality of life; Perfusion; Kirurgi;

   Abstract : The mortality of thoracic aortic diseases (mainly aneurysms and dissections) is high, even with surgical treatment. Epidemiology and long-term outcomes are incompletely investigated. Stroke is a major complication contributing to mortality, morbidity, and possibly to reduced quality of life. READ MORE

4. 2. Outcome and risk factors after aortic valve interventions

   Author : Per Kvidal; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic valve replacement; mechanical valve prosthesis; relative survival; morbidity; recurrent events; balloon aortic valvuloplasty; long-term follow-up; Kirurgi; Surgery; Kirurgi; kardiologi; Cardiology;

   Abstract : In the present study the long-term survival and morbidity and the associated risk factors after aortic valve replacement (AVR) and after aortic balloon valvuloplasty were evaluated. In a cohort of 2,359 consecutive patients undergoing primary aortic valve replacement, the early mortality was 5.6%. READ MORE

5. 3. Cardiac Function and Aortic Valve Intervention : Echocardiographic Studies of Myocardial Recovery in Patients with Severe Aortic Valve Disease

   Author : Lena Forsberg; Eva Nylander; Éva Tamás; Odd Bech-Hanssen; Linköpings universitet; []
   Keywords : ;

   Abstract : In patients with severe aortic valve disease, aortic valve intervention is performed when the risk for mortality or morbidity with conservative management is significantly increased. Left ventricular (LV) longitudinal motion decreases before conventional echocardiographic measures such as ejection fraction, are influenced in patients with severe aortic valve disease. READ MORE

6. 4. Aortic valve imaging - Towards new standards in prosthetic valve endocarditis

   Author : Erika Fagman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prosthetic valve endocarditis; aortic valve endocarditis; ECG-gated CT; cardiac CT; 18F-FDG PET CT;

   Abstract : Background: Aortic prosthetic valve endocarditis (PVE) is a disease with high mortality, and diagnosis is difficult. Transesophageal echocardiography (TEE) has been the mainstay imaging modality in the diagnostic workup, but TEE has diagnostic shortcomings. Thus, new imaging methods might improve the diagnostic workup of PVE. READ MORE

7. 5. Hope and life-struggle : patients' experiences with Transcatheter Aortic Valve Implantation

   Author : Karin Olsson; Åsa Hörnsten; Ulf Näslund; Jan Mårtensson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; transcatheter aortic valve implantation; experiences; coping; decision-making; health-related quality of life; symptoms; function; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

   Abstract : The overall aim of this thesis is to explore experiences and self-reported outcomes from Transcatheter Aortic Valve Implantation, TAVI, among people with severe aortic stenosis. The thesis includes four studies. Study I-II are based on interviews performed the day before TAVI and Qualitative Concept Analysis was used for analysis. READ MORE
