[Advantages] 3DE measurements of cardiac chamber volumes do not rely on geometric assumptions about their shape, and are more reproducible and closer to values provided by cardiac magnetic resonance than 2D volumes [Limitations] 
Limited evidence exists about the reference values of cardiac chambers 3D volumes and the intervendor consistency of 3D quantitative parameters
