Which cardiac chambers are seen as enlarged in this chest X-ray?
Double atrial density suggesting left atrial enlargement is seen within the right cardiac border. The right atrium is also enlarged, considering the significant shift of the right cardiac border to the right.
The distance from the midline to the right cardiac border is increased, another feature of right atrial enlargement. Right descending pulmonary artery shadow is also a little prominent, suggesting pulmonary hypertension.Correspondingly, pulmonary bay is obliterated, indicating mild enlargement of main pulmonary artery as well.
