Key result
Global longitudinal strain assessment was comparable between GE EchoPac and Toshiba Wall Motion Tracking software (-21.95% vs -22.28%, P=NS), showing narrower limits of agreement than other parameters.
Why the study?
Do different commercially available speckle-tracking software systems (GE vs Toshiba) provide comparable measurements of global myocardial strain in healthy subjects?

GLS measurements may be interchangeable between GE and Toshiba platforms in healthy subjects; leaves open validation in patients with cardiac disease.

Do different commercially available speckle-tracking software systems (GE vs Toshiba) provide comparable measurements of global myocardial strain in healthy subjects?
Absolute Event Rate: -21.95% vs -22.28%
p-value: p=NS
Two commercially available speckle-tracking software systems provide comparable measurements of left ventricular function, with global longitudinal strain being the most robust parameter across different platforms.
Manovel et al. (2010) conducted a cross-sectional in Healthy population (n=28). Vivid 7 with 2D-strain EchoPac PC vs. Artida 4D with 2D Wall Motion Tracking was evaluated on Global longitudinal strain (p=NS). Global longitudinal strain assessment was comparable between GE EchoPac and Toshiba Wall Motion Tracking software (-21.95% vs -22.28%, P=NS), showing narrower limits of agreement than other parameters.
