Assessment of myocardial elastography performance in phantoms under combined physiologic motion configurations with preliminary in vivo feasibility
TL;DR: This study shows ME to be capable of accurately depicting and distinguishing between different types of motion schemes, and to be sensitive to stiffness changes in localized regions of tissue-mimicking phantoms under physiologic cardiac motion configurations, while strains estimated in the combined motion scheme were noisier than in individual motion schemes.

TL;DR: Results indicate that high frame rate ultrasound imaging processed with CFWI has the potential to be a valuable tool for mechanical activation detection.

TL;DR: Multiple single quantitative parameters showed limited predictive ability to identify significant coronary artery stenosis and visual assessment of DSE appears to be more accurate than single velocity and strain/strain rate markers in the diagnosis of CAD.
Journal ArticleDOI
Assessment of Left Ventricular Systolic Function by Echocardiography
TL;DR: Echocardiography has defined the transition from compensated hypertrophy to left ventricle dilatation and progression to end-stage heart failure and demonstrated their efficacy in heart failure trials.

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.
