  1. 1. Physiological aspects on intracardiac blood flow

    Författare :Per Arvidsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.

  3. 2. Hemodynamic aspects of biventricular pacing in heart failure

    Författare :Marcus Ståhlberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Heart failure; biventricular pacing; hemodynamic monitoring; heart rate; cardiac output;

    Sammanfattning : Background and aims: Biventricular pacing or cardiac resynchronization therapy (CRT) is an established treatment option for selected heart failure (HF) patients. We aimed at evaluating acute and longer-term hemodynamic effects of different pacemaker programmings in CRT patients. LÄS MER

  4. 3. Hemodynamic assessment in patients with congenital heart disease using magnetic resonance imaging

    Författare :Pia Sjöberg; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Around 1000 children are born with a heart disease in Sweden every year and today most of these children survive and reach adult age. There are around 2.3 million grownups with congenital heart disease in Europe today, a number that is expected to continue to increase. LÄS MER

  5. 4. Fast and Accurate 4D Flow MRI for Cardiovascular Blood Flow Assessment

    Författare :Sven Petersson; Tino Ebbers; Oliver Wieben; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The study of blood flow is essential in understanding the physiology and pathophysiology of the cardiovascular system. Small disturbances of the blood flow may over time evolve and contribute to cardiovascular pathology. LÄS MER

  7. 5. Haemodynamic management in liver surgery

    Författare :Lena Sand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; liver resection; nitroglycerine; central venous pressure; vasopressin; patient position; PEEP;

    Sammanfattning : Background: Liver resection surgery is a potentially curative treatment for liver tumours. The liver is a highly vascular organ, and substantial intra-operative blood loss is common. Increased blood loss negatively impacts both postoperative outcome and long-term survival. LÄS MER
