The left aortic arch and right descending aorta.
Three patients with a left arch and a right descending aorta are described, all presenting in infancy. In one patient the abnormality was acquired, yet the radiological appearances were very similar. The place of the barium swallow in the diagnosis is discussed, and it is concluded that aortography is required for a definitive diagnosis.
