1. 1. Outcome and risk factors after aortic valve interventions

   Författare :Per Kvidal; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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%. LÄS MER

3. 2. Atrial fibrillation after cardiac surgery : an analysis of risk factors, mechanisms, and survival effects

   Författare :Giovanni Mariscalco; Bengt Åberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; adult; cardiac surgery; coronary artery bypass grafting; valvular surgery; cardiopulmonary bypass; mortalilty; histology; catecholamines; embolism; Surgery; Kirurgi;

   Sammanfattning : Background: Despite the recent improvements in surgical techniques and postoperative patient care, atrial fibrillation (AF) remains the most frequent complication after cardiac surgery. Although postoperative AF is often regarded as a benign clinical condition, this arrhythmia has significant adverse effects on patient recovery and postoperative survival. LÄS MER

4. 3. Thoracic Aortic Surgery : Epidemiology, Outcomes, and Prevention of Cerebral Complications

   Författare :Christian Olsson; Stefan Thelin; Jan van der Linden; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. Transcatheter Aortic Valve Implantation: Risk Assessment and Clinical Outcome

   Författare :Malin Johansson; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Key words: Aortic stenosis; transcatheter aortic valve implantation; outcome; acute kidney injury;

   Sammanfattning : Abstract Background: Transcatheter aortic valve implantation (TAVI) has emerged as a treatment for patients with aortic stenosis (AS) and high surgical risk. To date, reports of short- and mid-term survival have been favourable. The aim of this thesis was to evaluate early safety, risk assessment and late survival following TAVI. LÄS MER

7. 5. Surgical treatment in chronic aortic regurgitation : Timing, results, prognosis and left ventricular function

   Författare :Éva Tamás; Christian Olin; Eva Nylander; Mats Broqvist; Dan Lindblom; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic regurgitation; left ventricular function; exercise; physical capacity; echocardiography; Thoracic surgery; Thoraxkirurgi;

   Sammanfattning : Chronic aortic regurgitation (AR) of varying degree affects 13% of men and 8.5% of women. In persons with severe AR, the expected length of life and its quality are influenced. LÄS MER
