From: Atrial septal defect in a patient with congenital disorder of glycosylation type 1a: a case report
a At our patient’s first visit (8-months old), chest radiography showed narrowing of aortic knob and enlargement of right atrial at the frontal position. b At the same time, pulmonary blood stasis and increase of lung markings were also found at the lateral position, those image features may have been caused by atrial septal defect. c When he was 3-years old, narrowing of aortic knob and enlargement of right atrial were improved slightly compared with his first visit. d However, at the lateral position, increase of lung markings and pulmonary blood stasis were obviously aggravated compared with his first visit, those image features were attributed to the deterioration of atrial septal defect
