Key result
3DE provides more accurate and reproducible LV quantification than conventional 2DE.
Why the study?
Does three-dimensional echocardiography improve the accuracy and reproducibility of left ventricular assessment compared to conventional two-dimensional echocardiography?
Does three-dimensional echocardiography improve the accuracy and reproducibility of left ventricular assessment compared to conventional two-dimensional echocardiography?
Three-dimensional echocardiography overcomes geometric assumptions of 2DE and should be incorporated into routine clinical practice for patients requiring precise assessment of left ventricular size and function.
Should not yet change LV assessment practice; leaves open need for outcome trials of 3D versus 2D echocardiography.
Three-dimensional echocardiography is a novel imaging technique based on acquisition and display of volumetric data sets in the beating heart. This permits a comprehensive evaluation of left ventricular (LV) anatomy and function from a single acquisition and expands the diagnostic possibilities of noninvasive cardiology. It provides the possibility of quantitating geometry and function of LV without preestablished assumptions regarding cardiac chamber shape and allows an echocardiographic assessment of the LV that is less operator-dependent and therefore more reproducible. Further developments and improvements for widespread routine applications include higher spatial and temporal resolution to improve image quality, faster acquisition, processing and reconstruction, and fully automated quantitative analysis. At present, three-dimensional echocardiography complements routine 2DE in clinical practice, overcoming some of its limitations and offering additional valuable information that has led to recommending its use for routine assessment of the LV of patients in whom information about LV size and function is critical for their clinical management.

Luigi P. Badano (2014) conducted a review in Left ventricular evaluation and cardiac pathology. Three-dimensional echocardiography vs. Two-dimensional echocardiography (2DE) was evaluated. Three-dimensional echocardiography provides more reproducible and accurate quantitative evaluation of left ventricular geometry and function than conventional two-dimensional echocardiography.
