Infracardiac total anomalous pulmonary venous return

Echocardiogram confirmed a diagnosis of infracardiac TAPVR.

When assessing a chest radiograph in suspected congentialcongenital heart disease, there are two important questions to ask before forming a differential diagnosis:

1)

1. Is the child cyanotic or acyanotic?

2)

2. Is there increased or decreased pulmonary blood flow on chest x-ray?

This helps the radiologist formulate a differential diagnosis that should correlate with the echographixechocardiographic findings.

This is a case of cyanotic congentialcongenital heart disease with increased pulmonary blood flow on chest radiograph. Differential diagnosis includes: TransposiitonTransposition of the great arteries, Truncus arteriosus, Total anomalous pulmonary venous return, Large AVSD, Single ventricle without pulmonary stenosis.

Mild cardiomegaly with right chamber enlargement. Increased pulmonary blood flow with mild pulmonary oedema.
