Key result
Three-dimensional echocardiography measured significantly larger right atrial maximal volumes (52 vs 41 mL) and total emptying fractions (63% vs 58%) than two-dimensional echocardiography (P<0.0001).
Why the study?
What are the normative reference values for right atrial volumes and function assessed by 3D and speckle-tracking echocardiography in healthy volunteers?
Observational (n=200)

p-value: p=<0.0001
The study provides normative reference values for right atrial volumes and function measured by 3DE and 2D-STE across a wide age range of healthy subjects.

3D echocardiography yields larger right atrial volumes than 2D; supports method-specific norms but leaves standardization open.
Peluso et al. (2013) conducted an observational in Healthy volunteers (n=200). Three-dimensional echocardiography (3DE) vs. Two-dimensional echocardiography (2DE) was evaluated on Right atrial maximal volume (Vmax) (p=<0.0001). Three-dimensional echocardiography measured significantly larger right atrial maximal volumes (52 vs 41 mL) and total emptying fractions (63% vs 58%) than two-dimensional echocardiography (P<0.0001).
