The Clinical Benefits of Adding a Third Dimension to Assess the Left Ventricle with Echocardiography

Figure 10

Schematic representation of the biplane disc summation algorithm based on the measurement of left ventricular areas and long axis lengths on 4- and 2-chamber two-dimensional views of the left ventricle. To obtain accurate calculation of left ventricular volume the difference between the long axes measured in 4- and 2-chamber apical views should not be larger than 10%.
