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

    Author : Giovanni Mariscalco; Bengt Åberg; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

    Abstract : 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. READ MORE

  2. 2. Cardiovascular risk factors in aortic stenosis

    Author : Johan Ljungberg; Stefan Söderberg; Bengt Johansson; Peter Nilsson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Valvular heart disease; aortic stenosis; bicuspid aortic valve; cardiovascular risk factors; hypertension; diabetes mellitus; smoking; hypercholesterolemia; obesity; shrunken pore; renal failure; Epidemiology; epidemiologi; Cardiology; kardiologi;

    Abstract : 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%. READ MORE

  3. 3. Midgut carcinoid tumours - biochemical and therapeutic aspects

    Author : Gunnel Westberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carcinoid syndrome; valvular heart disease; 5-HT; chromogranins; octreotide; hepatic arterial embolization;

    Abstract : 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. READ MORE

  4. 4. The bicuspid aortic valve - studies on valve morphology and pathology in relation to ascending aortic dilatation and coronary artery disease

    Author : Veronica Jackson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : 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 co nditions such as ascending aortic aneurysm and aortic dissection. Of BAV individuals, 25 - 50% will develop indication s for surgical intervention . READ MORE

  5. 5. Impact of Surgical Techniques Used for Mitral Valve Repair on Hemodynamic Performance

    Author : Sigurdur Ragnarsson; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitral valve repair; artificial chordae; outcome; right ventricular function; infective endocarditis; mitral valve repair; artificial chordae; right ventricular function; outcome; infective endocarditis;

    Abstract : AbstractBackground Mitral regurgitation (MR) has many etiologies; the most common is degenerative disease. If not corrected, severe MR may cause left and right ventricular heart failure. Mitral valve (MV) repair is the gold standard for treatment of MR. READ MORE
