In this paper, the authors assess the feasibility of 2D strain, a software for real-time quantitative echocardiographic assessment of myocardial function, which is based on the estimation that a discrete set of tissue velocities are present per each of many small elements on the ultrasound image.Abstract:
Objectives We sought to assess the feasibility of 2-dimensional strain, a novel software for real-time quantitative echocardiographic assessment of myocardial function Methods Conventional and a novel non-Doppler–based echocardiography technique for advanced wall-motion analysis were performed in 20 patients with myocardial infarction and 10 healthy volunteers from the apical views Two-dimensional strain is on the basis of the estimation that a discrete set of tissue velocities are present per each of many small elements on the ultrasound image This software permits real-time assessment of myocardial velocities, strain, and strain rate These parameters were also compared with Doppler tissue imaging measurements in 10 additional patients Results In all, 803% of infarct and 978% of normal segments could be adequately tracked by the software Peak systolic strain, strain rate, and peak systolic myocardial velocities, calculated from the software, were significantly higher in the normal than in the infarct segments In the 10 additional patients, velocities, strain, and strain rate obtained with the novel software were not significantly different from those obtained with Doppler tissue imaging Conclusion Two-dimensional strain can accomplish real-time wall-motion analysis, and has the potential to become a standard for real-time automatic echocardiographic assessment of cardiac functionread more

TL;DR: It is the opinion that current technology justifies the clinical use of the quantitative two-dimensional methods described in this article and the routine reporting of left ventricular ejection fraction, diastolic volume, mass, and wall motion score.

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.

Global longitudinal strain: a novel index of left ventricular systolic function.
TL;DR: GLS and GLSR are novel indices for assessment of global LV function from 2-dimensional echocardiographic images and early validation studies with the method are suggestive of high sensitivity and specificity in the detection of LV systolic dysfunction in patients post-MI.
