Overview

Chest x rays may detect an atrial septal defect. Chest x rays can be limited in imaging quality and may only supplement other imaging modalities. The chest x-ray may demonstrate cardiomegaly (right ventricle and right atrial enlargement), a prominent pulmonary artery segment and increased pulmonary vascular markings.

Chest X Ray

Common Findings

CXR findings on an anteroposterior view of the chest x-ray in atrial septal defect may include: [1]

1) Prominent pulmonary artery, increased pulmonary vascular markings.

2) Cardiomegaly due to right atrial and ventricular enlargement.

3)' Triangular appearance of the heart

  • Results from enlargement of pulmonary arteries preventing the ascending and transverse aorta from forming normal heart borders.

4) Scimitar sign

5) Dilatation of the superior vena cava can be seen in sinus venosus
