Key result
Two-dimensional echocardiography is limited by geometric assumptions that cause inaccuracy and variability in measuring ventricular volume and function.
The text highlights the limitations of 2-D echocardiography in assessing complex cardiac disorders and ventricular volumes, setting the stage for three-dimensional echocardiography.
Supports cautious interpretation of 2D volumes in complex cases; leaves open optimal adoption of 3D echocardiography pending validation.
Although 2-D echocardiography (2DE) was a major step forwards for the non-invasive assessment of cardiac structure and function, the diagnosis of complex disorders remained a difficult mental conceptualisation process. In addition, the measurement of left ventricular (LV) volume and function, the most common referral reason for echocardiography, required important geometric assumptions about its shape, causing inaccuracy and significant variability. Also, quantitative assessment of the right ventricle with its peculiar shape continued to be elusive.

Jos R.T.C. Roelandt (2006) conducted a review in Cardiac structural and functional disorders. Three-dimensional Echocardiography vs. 2-D echocardiography was evaluated. Two-dimensional echocardiography is limited by geometric assumptions that cause inaccuracy and variability in measuring ventricular volume and function.
