Newborn with an abnormal fetal echo

CT of interrupted aortic arch
Axial CT with contrast of the heart (above), obtained in a venous phase, shows discontinuity of the ascending and descending aorta while the sagittal image (below right) shows a dilated patent ductus arteriosus reconstituting the descending aorta and the coronal image (below left) shows dextrocardia.

The diagnosis was interrupted aortic arch supplied by a patent ductus arteriosus in a patient with dextrocardia.
