  1. 1. Surgically corrected univentricular hearts. Anatomical, haemodynamic and functional status at a long-term follow-up

    Författare :Eva Strömvall-Larsson; Göteborgs universitet; []
    Nyckelord :cavopulmonary connections; univentricular hearts; long-term follow-up; pulmonary; arteriovenous malformations; lung volumes; cardiac output; pulmonary gas exchange and maximal; exercise studies;

    Sammanfattning : The Fontan operation and its modifications are applied to a large spectrum of congenital heart defectswith univentricular physiology. The Fontan circulation is characterised by a reduced, non-pulsatilepulmonary blood flow and the elevated central venous pressure is the main driving force for thepulmonary blood flow. LÄS MER

  3. 2. The bone cement implantation syndrome - epidemiology, pathophysiology and prevention

    Författare :Mathias Hård af Segerstad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone cement implantation syndrome; femoral neck fracture; cemented hip hemiarthroplasty; pulmonary haemodynamic; right ventricle ejection fraction; pulmonary vascular resistance; hemiarthroplasty;

    Sammanfattning : Bone cementation implantation syndrome (BCIS) has significant morbidity and mortality for patients who are undergoing cemented hip hemiarthroplasty or arthroplasty. The aim of this thesis is to contribute with information of the epidemiological parameters of BCIS and identify risk factors. LÄS MER

  4. 3. Pulmonary Hypertension and the Nitric Oxide System

    Författare :Dan Henrohn; Gerhard Wikström; Ulla Lindqvist; John Pernow; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pulmonary hypertension; nitric oxide; ADMA; arginine; nitrate; nitrite; vardenafil; beetroot juice; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Pulmonary hypertension (PH) is a pathophysiological state associated with several medical conditions, leading to progressive rise in pulmonary vascular resistance (PVR) and right ventricular failure. The clinical PH classification encompasses five main World Health Organization (WHO) groups; pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung diseases and/or hypoxia, chronic thromboembolic PH, and PH with unclear multifactorial mechanisms.

  5. 4. Haemodynamic and ventilatory effects of laparoscopic surgery

    Författare :Lena Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Laparoscopy; C02 pneumoperitoneum; indicator- dilution technique; central haemodynamics; cardiac output; central blood volume; venous occlusion plethysmography; catecholamines; multiple inert gas technique; shunt; abdominal wall lift; intrathoracic pressure; ventilation-perfusion matching; atelectasis; spiral computed tomography.;

    Sammanfattning : Background: It has been shown repeatedly that the establishment of pneumoperitoneum (PP) is associated with increased cardiac filling pressures, as well as increased blood pressure and systemic vascular resistance. Patients without heart or lung disease can compensate for these effects of PP, but cardiopulmonary compromised patients may develop cardiac failure during PP. LÄS MER

  7. 5. Acute and long-term effects of pulmonary embolism on heart function and lung circulation

    Författare :Ary Ribeiro; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Pulmonary embolism; pulmonary heart disease; follow-up studies; nuclear medicine; perfusion; echocardiography; ventricular function; statistics; time-course;

    Sammanfattning : Objectives: To describe the course over time of pulmonary artery systolic pressure (PAsP) and right ventricle (RV) function assessed with echocardiography-Doppler (E-D) and extent of perfusion defects (PDf) on lung scintigraphy (LS) and to identify patients at increased risk for death or for chronic pulmonary hypertension (PH), after pulmonary embolism (PE). Design: Prospective follow-up studies with cross-sectional analyses. LÄS MER
