  2. 1. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

    Author : Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Abstract : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. READ MORE

  4. 2. Pulmonary hypertension. Clinical and pathophysiological studies

    Author : Nedim Selimovic; Göteborgs universitet; []
    Keywords : Pulmonary hypertension; Echocardiography; Right heart catheterisation; Pulmonary vascular resistance; Pulmonary function tests; Lung transplantation; Mortality on the waiting list; Vascular remodelling; Growth substances; Inflammation; Endothelin;

    Abstract : Pulmonary hypertension (PH) is a common abnormality, most often associated with various cardiopulmonary diseases. Pulmonary arterial hypertension (PAH) is a devastating pulmonary vascular disease characterised by the proliferation of endothelial, smooth-muscle cells and fibroblasts. READ MORE

  5. 3. Continuous ambulatory hemodynamic monitoring with an implantable system : the feasibility of a new technique

    Author : Åke Ohlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : heartfailure; hemodynamic monitoring; implantable; oxygen saturation; pressure; ambulatory; right ventricle; dPdt; long-term; sensor; cardiac output.;

    Abstract : Patients with chronic heart failure constitute an increasingly large group. Despite recent therapeutic improvements, these patients have a poor prognosis. READ MORE

  6. 4. Diagnosis of interatrial shunts and the influence of patent foramen ovale on oxygen desaturation in obstructive sleep apnea

    Author : Magnus C Johansson; Göteborgs universitet; []
    Keywords : Patent foramen ovale; atrial septal defect; obstructive sleep apnea; contrast transesophageal echocardiography; percutaneous closure;

    Abstract : Patent foramen ovale (PFO) is found in 27% of the population and although mostly asymptomatic, PFO has been associated with e.g. cryptogenic stroke and, rarely, also with oxygen desaturation. PFO and atrial septal defects may nowadays be closed percutaneously without open heart surgery. READ MORE

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

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

    Abstract : 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. READ MORE
