  1. 1. Coarctation of the aorta : register and imaging studies

    Författare :Daniel Rinnström; Bengt Johansson; Michael Henein; Martin Ugander; Gerhard-Paul Diller; Umeå universitet; []

    Sammanfattning : Background Coarctation of the aorta (CoA) constitutes 5-8 % of all congenital heart disease (CHD) and is associated with long-term complications such as hypertension (HTN) and left ventricular hypertrophy (LVH). Factors associated with HTN, LVH, and diffuse myocardial fibrosis, are not yet fully explored in this population. LÄS MER

  2. 2. Aortic coarctation : Physiological and model studies

    Författare :Jan Engvall; Dag Teien; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In 22 patients, referred for the assessment of significant native- or re-coarctation, the systolic cuff blood pressure difference between arm and ankle at rest and after three different subrnaximal exercise tests and one maximal test was compared with invasive blood pressure. Reference values of cuff blood pressure were obtained from 19 healthy adult volunteers. LÄS MER

  3. 3. The effect of pressure afterload due to aortic coarctation on left ventricular function in children

    Författare :Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coarctation of the aorta; congenital aortic stenosis; left ventricle; myocardial deformation imaging; speckle tracking echocardiography; longitudinal strain; aorto-septal angle; children; Cardiology; kardiologi;

    Sammanfattning : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. LÄS MER

  4. 4. Functional and morphological MR studies in congenital cardiovascular malformations

    Författare :Catarina Holmqvist; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; Contrast-enhanced MR angiography.; Coarctation; Intra-cardiac shunts; Conduits; Tetralogy of Fallot; Function; Flow; MR velocity mapping; Infants; Children; Magnetic Resonance Imaging; Angiocardiography; Heart; Congenital heart defects; medical instrumentation; tomography; radiology; Clinical physics;

    Sammanfattning : The aim of this study was to evaluate new MR techniques permitting qualitative and quantitative analysis of cardiac function and measurement of velocity and flow, and later on contrast-enhanced MR angiography, techniques largely unexplored in children with CHD. Infants with tetralogy of Fallot and pulmonary atresia with ventricular septal defect were examined pre-operatively. LÄS MER

  5. 5. Cardiovascular disease in patients with congenital heart disease

    Författare :Maria Fedchenko; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital heart disease; Myocardial infarction; Ischemic heart disease; Coarctation of the aorta; Cardiovascular risk factor;

    Sammanfattning : Background: Today, about 95% of children with congenital heart disease (CHD) survive into adulthood and the survival in patients with CHD has increased considerably during the last decades. With increasing age, patients with CHD are at an increased risk of developing acquired cardiovascular disease, such as ischemic heart disease and myocardial infarction (MI). LÄS MER
