1. Atrial fibrillation after cardiac surgery : an analysis of risk factors, mechanisms, and survival effects
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
2. Cardiovascular risk factors in aortic stenosis
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
3. Midgut carcinoid tumours - biochemical and therapeutic aspects
Sammanfattning : The biology of human midgut carcinoid tumour was studied experimentally in primary cell culture and clinically in patients with the midgut carcinoid syndrome. In cell cultures, tumour cells had a secretory pattern of 5-HTP, 5-HT and 5-HIAA specific for each tumour indicating individual regulation of synthesis/degradation. LÄS MER
4. Clinical Outcomes of Transcatheter Aortic Valve Implantation (TAVI)
Sammanfattning : Aortic stenosis (AS) is the most common valvular heart disease and most prevalent in the elderly. In the latest decades, a new method for replacement of the aortic valve: transcatheter aortic valve implantation (TAVI) has been introduced. LÄS MER
5. The bicuspid aortic valve : studies on valve morphology and pathology in relation to ascending aortic dilatation and coronary artery disease
Sammanfattning : The prevalence of bicuspid aortic valve (BAV) is 1-2% and is thereby the most common cardiac malformation. BAV is highly associated with valvular dysfunction and aortic conditions such as ascending aortic aneurysm and aortic dissection. Of BAV individuals, 25-50% will develop indications for surgical intervention. LÄS MER
