In vitro findings support 3DE optimization for LV volumetry; leaves open clinical translation without human validation studies.
Does three-dimensional echocardiography improve the accuracy of left ventricular volume quantitation compared to two-dimensional echocardiography in an in vitro model?
In an in vitro model, 3DE volumetry using short-axis slices with a thickness of 15 mm provides the most rational balance between accuracy and analysis time for left ventricular volume quantitation.
Nixdorff et al. (2005) studied this question.
