Interruption of the aortic arch with complete transposition of the great arteries. Clinical and angiocardiographic diagnosis at the age of one day.

The association of complete transportation of the great arteries and complete interruption of the aortic arch is very rare. This combined lesion was diagnosed clinically in a 1-day-old infant in whom it caused cyanosis of the upper half of the body. The diagnosis was confirmed angiocardiographically. We believe this is the youngest patient in whom this diagnosis was made in vivo.
