What do oligemia in the lungs, pulmonary bay, and right ventricular hypertrophy in an X-ray chest indicate?

Hello,

Welcome to icliniq.com

The baby's chest X-ray with oligemia in the lungs, pulmonary bay, right-sided aorta, and right ventricular hypertrophy is suggestive of a congenital heart defect, likely an atrial septal defect that is a hole in the partition of the heart. It will require dedicated work about the defect's size, cardiac function, shunt evaluation regarding the mixing of oxygenated and de-oxygenated blood, and structural modulations secondary to the defect. I would suggest a 2D echocardiogram for follow-up.

Thank you.
