- A chest x-ray may be helpful in the diagnosis of tricuspid atresia. Findings on an x-ray suggestive of tricuspid atresia include
Situs solitus
Left-sided aortic arch
Levocardia
Absent main pulmonary artery
Pulmonary oligemia with decreased vascular markings
Right aortic arch in %25 of cases.

Shown below is an example of chest x-ray in a patient with tricuspid atresia demonstrating the following features:

The left anterior oblique projection on the right side shows the distinctive humped appearance of the anterior cardiac silhouette due to

right atrial (RA) enlargement

absence of a right ventricle.

The left ventricle (LV) is enlarged.

(c) A right aortic arch may be observed in some cases.
