TL;DR: The STI estimation of LVtor is concordant with those analyzed by tagged MRI and also showed good agreement with those by DTI (data derived from tissue velocity) and may make the assessment more available in clinical and research cardiology.

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.

TL;DR: This multicenter study of nearly 250 volunteers without evidence of cardiovascular disease showed an average LV peak systolic strain of -18.6 +/- 0.1% and there was significant segmental variation of regional strain to necessitate the use of site-specific normal ranges.

TL;DR: A novel approach is elaborated mimicking the human observer who reaches robust diagnosis upon the B-mode data and enhancements of the method using spline fitting are introduced.

TL;DR: After direct observation of the valves, Doppler evaluation is the best means for characterizing end-diastole and end-systole during speckle-tracking (STI) analysis and has a major impact on the accuracy of strain measurements.
