Congenital Heart Disease

Background:

Right atrial malformations are rare cardiac abnormalities.
Often reported as isolated findings in medical literature.

Observation:

Prenatal giant atrial dilatation was diagnosed in an asymptomatic infant.
The infant underwent surgical treatment at 18 months due to risks of thrombosis and arrhythmias.

Findings:

Post-surgical echocardiography revealed residual elevated atrial pressure.
Right atrial dilatation can conceal an underlying restrictive right ventricle.

Implications:

This case highlights the importance of thorough cardiac evaluation in cases of atrial dilatation.
Early surgical intervention may be necessary to mitigate risks associated with this condition.
