Hoffman-Rigler sign (heart)

The Hoffman-Rigler sign is a sign of left ventricular enlargement where an approximation of the distance between the inferior vena cava (IVC) and left ventricle is used.​

Radiographic features

On a lateral chest radiograph, if the distance between the left ventricular border and the posterior border of IVC exceeds 1.8 cm, at a level 2 cm above the intersection of diaphragm and IVC, left ventricular enlargement is suggested 1.

Later investigators suggest this should be increased to 1.9 cm to decrease the number of false positives 2.

Prior to their publication in 1951, LV enlargement was suggested when the posterior LV border is more than 1.5 cm posterior to the IVC.

Practical points

Hoffman-Rigler sign should not be confused with Riglers sign, Rigler's triad or Rigler notch sign.
