Description

In X-ray, a rule or sign for determining left ventricle enlargement on a lateral view.

It is done by drawing a 2.0-cm vertical line upward along the inferior vena cava from the point where the posterior wall of the left ventricle and inferior vena cava cross in the lateral projection.

From this point, a second line is drawn parallel to the vertebral bodies. If the distance between the left ventricular border and the vertical line exceeds 1.8 cm, left ventricular enlargement is suggested.
