  1. 1. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies

    Författare :Gylfi Oskarsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; Cardiovascular system; Kardiovaskulära systemet; fetal asphyxia; transposition of the great arteries; dilated cardiomyopathy; aortic stenosis; child; neonate; adenosine; coronary flow reserve; Doppler; coronary flow;

    Sammanfattning : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. LÄS MER

    Författare :Elhadi Aburawi; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; cardiopulmonary bypass; transthoracic Doppler echocardiography; coronary flow; Pediatri; endothelial dysfunction; C-reactive protein; Medicin människa och djur ; Pediatrics; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Factors Affecting Coronary Flow in Children Elhadi H. Aburawi, MD, MSc, FRCPI, FRCPCH Division of Paediatric Cardiology, Department of Paediatrics, Lund University, Sweden Abstract Background: A number of inborn and exogenous factors influence the flow and function of the coronary arteries with possible consequences on the cardiovascular risk.

  3. 3. Coronary Reactive Hyperemia

    Författare :Göran Olivecrona; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Medicin människa och djur ; Medicine human and vertebrates ; t-PA; P2Y1-receptors; Hypothermia; Coronary; Reactive hyperemia;

    Sammanfattning : Introduction: The mechanism of post ischemic reactive hyperemia is still unknown but now thought to be multifactorial and perhaps involving purinergic signalling. Purines such as ATP and ADP have recently been discovered to play a vital role in the regulation of vascular tone. LÄS MER

  4. 4. A minimally invasive axial blood flow pump : an experimental and clinical study

    Författare :Urban Lönn; Howard Frazier; Linköpings universitet; []
    Nyckelord :Axial blood flow pump; Hemopump; LVAD; Beating heart CABG; MEDICINE; MEDICIN;

    Sammanfattning : The first aim of this thesis was to evaluate a new minimally invasive axial blood flow pump for treatment of patients needing circulatory support after open heart surgery. This system, the Hemopump temporary cardiac assist device, is a very small catheter mounted intracorporeal pump, which is introduced transvalvularly into the left ventricle. LÄS MER

  5. 5. Aortic valvular flow : a clinical and experimental doppler echocardiographic study

    Författare :Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. LÄS MER
