Why the study?
Does frame and volume rate affect the concordance between 2D, 3D, and triplane speckle tracking strain in patients evaluated for subclinical LV function?
Population
142 prospectively recruited patients who underwent evaluation of subclinical left ventricle (LV) function
Comparison
Three-dimensional speckle tracking strain and… vs Two-dimensional speckle tracking strain (2DS)
Design
Cohort

Strain values from different modalities should not be interchanged in subclinical LV assessment; this cohort study leaves open whether volume rate optimization enhances 3D concordance.
Does frame and volume rate affect the concordance between 2D, 3D, and triplane speckle tracking strain in patients evaluated for subclinical LV function?
Strain values are not interchangeable among 2D, 3D, and triplane speckle tracking, with poor correlations driven by differences in acquisition rates, making 2D strain currently the most robust measurement.
