Box-shaped heart
A box-shaped heart is a radiographic description given to the cardiac silhouette in some cases of Ebstein anomaly. The classic appearance of this finding is caused by the combination of the following features:
- huge right atrium that may fill the entire right hemithorax
- shelved appearance of the left cardiac contour due to the dilated right ventricular outflow tract or elevated residual right ventricle
- small aorta and main pulmonary artery
