Three-dimensional visual guidance improves the accuracy of calculating right ventricular volume with two-dimensional echocardiography.


Three-dimensional guidance programs have been shown to increase the reproducibility of 2-dimensional (2D) left ventricular volume calculations, but these systems have not been tested in 2D measurements of the right ventricle. Using magnetic fields to identify the probe location, we developed a new 3-dimensional guidance system that displays the line of… (More)
