Key result
Three-dimensional left ventricular strain analysis provides comprehensive LV function assessment but has lower feasibility (85% vs 91%) and significant inter-vendor variability compared to 2D strain.
Why the study?
Transthoracic 3D echocardiography speckle tracking strain measurements offer advantages over 2D strain by assessing the entire left ventricular myocardium, warranting a review of its current status, validation, and clinical applications.
Does 3D left ventricular myocardial strain analysis provide added value over 2D strain in assessing global and regional LV function?

Cautions against routine 3D strain use in practice due to feasibility and variability limits; challenges assumptions of broad 3D superiority over 2D.
Does 3D left ventricular myocardial strain analysis provide added value over 2D strain in assessing global and regional LV function?
3D LV myocardial strain analysis offers advantages over 2D strain by providing more accurate estimates of global and regional LV function derived from the entire myocardium.
Nabeshima et al. (2020) conducted a review in Left ventricular dysfunction. Three-dimensional (3D) left ventricular myocardial strain analysis vs. Two-dimensional (2D) strain analysis was evaluated. Three-dimensional left ventricular strain analysis provides comprehensive LV function assessment but has lower feasibility (85% vs 91%) and significant inter-vendor variability compared to 2D strain.
