2. 1. Multidimensional MRI  of Myocardial Dynamics : Acquisition, Reconstruction and Visualization

   Author : Andreas Sigfridsson; Hans Knutsson; Sebastian Kozerke; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Cardiac motion; myocardial dynamics; strain; tensor; deformation; DENSE; k-t BLAST; Medical engineering; Medicinsk teknik;

   Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. READ MORE

4. 2. Magnetic Resonance Imaging of Myocardial Deformation and Scarring in Coronary Artery Disease

   Author : Johan Kihlberg; Jan Engvall; Tino Ebbers; Anders Persson; Åse Johnsson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Although improved treatments have reduced the rates of acute complications from myocardial infarction, sequelae such as heart failure and sudden death threaten the future wellbeing of those patients. Secondary prevention after myocardial infarction is related to cardiovascular risk factors and the effect of the infarct on left ventricular function. READ MORE

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

   Author : Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; Umeå universitet; []
   Keywords : 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; kardiologi; Cardiology;

   Abstract : 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. READ MORE

6. 4. Insights into the effect of myocardial revascularisation on electrical and mechanical cardiac function

   Author : Ihab Ramzy Guirguis; Michael Y Henein; Stellan Mörner; Reidar Winter; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial infarction; natriuretic peptides; echocardiography; ventricular function; atrial function; surgical revascularisation; speckle tracking echocardiography; Cardiology; kardiologi;

   Abstract : Background: Acute coronary syndrome is known for its effect on cardiac function and can lead to impaired segmental and even global myocardial function. Evidence exists that myocardial revascularisation whether pharmacological, interventional or surgical results in improvement of systolic and diastolic left ventricular (LV) function, particularly that of the long axis which represents the sub-endocardial function, known as the most sensitive layer to ischaemia.

7. 5. Quantification and Visualization of Cardiovascular Function using Ultrasound

   Author : Matilda Larsson; Lars-Åke Brodin; Hans Torp; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; Tissue Doppler imaging; Speckle tracking imaging; cardiovascular function; visualization; quantification; Medical engineering; Medicinsk teknik;

   Abstract : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. READ MORE
