Risk Assessment of Ventricular Arrhythmias in Patients with Nonischemic Dilated Cardiomyopathy by Strain Echocardiography
Kristina H. Haugaa,Björn Goebel,Thomas Dahlslett,Kathleen Meyer,Christian Jung,Alexander Lauten,Hans R. Figulla,Tudor C. Poerner,Thor Edvardsen,Thor Edvardsen +9 more
TL;DR: Strain echocardiography may help in the risk stratification of patients with DCM not fulfilling current implantable cardioverter-defibrillator indications and global longitudinal strain is a promising marker of arrhythmias.
Journal ArticleDOI
Myocardial strain rate is a superior method for evaluation of left ventricular subendocardial function compared with tissue Doppler imaging.
TL;DR: Strain and SR appear useful and sensitive for evaluating myocardial function, especially for the subendocardial region.

Early Prediction of Infarct Size by Strain Doppler Echocardiography After Coronary Reperfusion
Trond Vartdal,Harald Brunvand,Eirik Pettersen,Hans-Jørgen Smith,Erik Lyseggen,Thomas Helle-Valle,Helge Skulstad,Halfdan Ihlen,Thor Edvardsen +8 more
TL;DR: This study demonstrates that assessment of regional and global strain at 1.5 h after reperfusion therapy correlates with size and transmural extent of myocardial infarction as determined by contrast-enhanced MRI.
Journal ArticleDOI
Strain and strain rate deformation parameters: from tissue Doppler to 2D speckle tracking
TL;DR: Strain and strain rate deformation parameters based on Color Doppler Myocardial Imaging, and more recently on two-dimensional gray scale images, have evolved as important methods for the quantification of myocardial function.

TL;DR: Myocardial stiffness can be measured in real time over the cardiac cycle using SWI, which allows quantification of stiffness variation between systole and diastole and provides a noninvasive index of myocardial contractility.

Statistical methods for assessing agreement between two methods of clinical measurement.
TL;DR: An alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability.

Myocardial Strain by Doppler Echocardiography Validation of a New Method to Quantify Regional Myocardial Function
TL;DR: Myocardial strain by Doppler echocardiography may represent a new, powerful method for quantifying regional myocardial function and is less influenced by tethering effects than Dopplers tissue imaging.
Journal ArticleDOI
Real-time strain rate imaging of the left ventricle by ultrasound
TL;DR: In the healthy hearts, a spatially homogeneous distribution of the strain rate was found and all the infarcted areas in this study showed up as hypokinetic or akinetic, demonstrating that this method may be used for imaging of regional dysfunction.

TL;DR: The concomitant enhancement of the myocardial Doppler signal after an intravenous injection of a transpulmonary echocardiographic contrast agent could permit the noninvasive assessment of regional myocardIAL perfusion.
