Description
This is an infant heart showing a graft closing a high ventricular septal defect and a sutured atrial
septal defect. The origin of the aorta and pulmonary trunk are normal, but there is right ventricular
hypertrophy. The ductus appears closed, but there is evidence that it was a late closure in that the
pulmonary artery is ballooned out at the point of origin of the ductus. Viewed from above one can
see the right subclavian and carotid arteries arising separately from the arch with, close-by, the left
carotid artery arising. The left subclavian artery is arising some distance away.
