  1. 1. Evaluation of New Non-Pharmacological Therapies for Symptomatic Atrial Fibrillation : With Special Emphasis on the Maze Procedure

    Författare :Stefan Lönnerholm; Lennart Bergfeldt; Uppsala universitet; []
    Nyckelord :Medical sciences; Atrial fibrillation; Maze procedure; pacing; quality of life; förmaksflimmer; MEDICIN OCH VÅRD; Maze kirurgi; livskvalitet; MEDICINE; MEDICIN; kardiologi; Cardiology;

    Sammanfattning : Atrial fibrillation is a common disease. With pharmacological therapy most patients with atrial fibrillation have moderate or little symptoms, but a number of patients have severely symptomatic disease. This study evaluates two new non-pharmacological therapies for atrial fibrillation, the Maze procedure and atrial overdrive pacing. LÄS MER

  3. 2. Surgical treatment of atrial fibrillation : clinical, hormonal and electrophysiological aspects of the maze operation

    Författare :Anders Albåge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Atrial fibrillation (AF) is the most common arrhythmia, associated with significant mortality and morbidity, due to hemodynamic impairment and the increased risk of stroke. Traditional pharmacological treatment may be insufficient or cause intolerable side-effects. LÄS MER

  4. 3. Surgical Ablation of Atrial Fibrillation with Cryo and Radiofrequency Concomitant to Mitral Valve Surgery : Clinical, Biochemical and Echocardiography Outcomes

    Författare :Gabriella Boano; Farkas Vánky; Meriam Åström Aneq; Lena Jideus; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Mitral valve surgery; Surgical ablation; Cox-Maze IV; Left atrium remodelling; 3D echocardiography;

    Sammanfattning : Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. In cardiac surgery, the negative influence of AF on short- and long-term outcomes has made concomitant ablation procedures more common. LÄS MER

  5. 4. Neurochemical regulators of the septohippocampal pathway : role in spatial and aversive learning

    Författare :Elin Elvander Tottie; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Acetylcholine; muscarinic receptor; galanin; serotonin; 5-HT1A receptor; glutamate; NMDA receptor; water maze; passive avoidance; septum; hippocampus; learning; memory; spatial; aversive; emotional; cognition;

    Sammanfattning : The aim of this thesis was to investigate the significance of major neurotransmitters in the septohippocampal pathway for hippocampal-dependent learning and memory. The cholinergic and GABAergic neurons in the medial septal/vertical limb of the diagonal band of Broca area (MS/vDB) projecting to the hippocampus, constitute the septohippocampal pathway, which has been implicated in a number of important functions such as attention, anxietylike behavior and hippocampal-dependent learning and memory.

  7. 5. Aspects of Intraoperative Ablation for Atrial Fibrillation

    Författare :Birgitta Johansson; Göteborgs universitet; []
    Nyckelord :atrial fibrillation; intraoperative ablation; radiofrequency; cryo; epicardial; quality of life; atrial function; predictors of rhythm;

    Sammanfattning : Background: Increasing knowledge about mechanisms that trigger and maintain atrial fibrillation (AF) has influenced the possibilities for treatment and even cure of AF. The surgical Cox Maze III procedure is still the gold standard for the curative treatment of AF. LÄS MER
