Key result
3-Dimensional Speckle Tracking Imaging accurately estimated LV regional longitudinal (r=0.89), radial (r=0.84), and circumferential (r=0.90) strain compared to sonomicrometry (P<0.001).
Why the study?
Does 3-dimensional speckle tracking imaging accurately quantify regional myocardial deformation compared to sonomicrometry in an animal model?
Does 3-dimensional speckle tracking imaging accurately quantify regional myocardial deformation compared to sonomicrometry in an animal model?
Effect estimate: r=0.89 (LS), r=0.84 (RS), r=0.90 (CS)
p-value: p=<0.001
3D-STI is a reliable tool for estimating LV regional circumferential, longitudinal, and radial strain components, showing good correlation with sonomicrometry in an animal model.

Seo et al. (2009) studied Left ventricular myocardial function assessment (n=10). 3-Dimensional Speckle Tracking Imaging (3D-STI) vs. Sonomicrometry was evaluated on Correlation of segmental longitudinal (LS), radial (RS), and circumferential strain (CS) measurements (r=0.89 (LS), r=0.84 (RS), r=0.90 (CS), p=<0.001). 3-Dimensional Speckle Tracking Imaging accurately estimated LV regional longitudinal (r=0.89), radial (r=0.84), and circumferential (r=0.90) strain compared to sonomicrometry (P<0.001).
