Use of three-dimensional speckle tracking to assess left ventricular myocardial mechanics: inter-vendor consistency and reproducibility of strain measurements
Key result
Three-dimensional speckle-tracking echocardiography showed poor inter-vendor agreement between Artida and VividE9 systems for radial, circumferential, and area strain measurements (P<0.001).
Why the study?
Is there inter-vendor consistency in 3D left ventricular global strain values obtained using Artida versus VividE9 ultrasound systems?

Implication
Clinicians should not interchange 3D strain values across vendors; leaves open need for standardization and vendor-specific norms.

Badano et al. (2012) conducted a cross-sectional in Patients with a wide range of LV end-diastolic volumes and ejection fractions (n=60). 3D speckle-tracking echocardiography (Artida) vs. 3D speckle-tracking echocardiography (VividE9) was evaluated on Inter-vendor consistency of 3D LV global strain values. Three-dimensional speckle-tracking echocardiography showed poor inter-vendor agreement between Artida and VividE9 systems for radial, circumferential, and area strain measurements (P<0.001).
