Earth-heart sign

The earth-heart sign is a newly recognised sign of cardiac compromise that may be seen on chest radiographs of patients with tension pneumomediastinum.

The substantial pressure exerted on the heart by the air trapped in mediastinum with subsequent impairment of central venous return and obstruction of diastolic filling may lead to a flattening of the cardiac silhouette resembling the effects of spinning for millions of years of our globe leading to an oblate-spheroid, i.e. the earth-heart sign 1
