3D echocardiography provides improved accuracy and reproducibility over 2D methods for quantifying ventricular volumes and function in children and adults.
May support selective use of three-dimensional echocardiography; leaves open prospective outcome trials before guideline changes.
Quantitative measurement of left ventricular (LV) volumes, mass, and function is one of the most common and important indications for echocardiography. These measurements are among the most powerful tools for diagnosis and prognosis of congenital and acquired heart diseases and for assessment of medical, percutaneous, and surgical interventions. Awareness is also growing of the importance of right ventricular (RV) volume, mass, and function in many cardiopulmonary diseases. Furthermore, there are challenges and opportunities to measure the volume, mass, and function of complex chambers such as the left atrium, right atrium, and the univentricular heart. As echocardiography continues to be the imaging modality of choice for these measurements, the strengths and limitations of M-mode, two-dimensional (2D), and recently three-dimensional (3D) echocardiographic (3DE) methodologies for accurate and reproducible measurement of these indices have been extensively investigated for congenital and acquired heart diseases. Evidence suggests that 3DE provides improved accuracy and reproducibility over 2D methods for measurement of LV volume and function calculation in adults and in children. Data have accumulated on the utility of 3DE for measuring chamber volumes and function for the RV and for the single ventricle, which may become more widely used in clinical and research arenas in the future. Finally, new advanced modes of analysis such as 3D strain and synchrony analysis by 3DE are promising methodologies that warrant further investigation.

Balluz et al. (2013) conducted a review in Congenital and acquired heart diseases. Three-dimensional echocardiography (3DE) vs. Two-dimensional (2D) echocardiography was evaluated on Measurement of ventricular volume, mass, and function. Three-dimensional echocardiography provides improved accuracy and reproducibility over two-dimensional methods for measuring left ventricular volume and function in adults and children.
