Coronary arteriography using balloon occlusion of the aortic root in infants with transposition of the great arteries.

A simple technique of coronary arteriography using balloon occlusion of the aortic root is described. The technique has greatly helped in the selection of the arterial switch operation for infants with transposition of the great arteries (TGA) in whom accurate recognition of the anatomy of the coronary arteries is important and yet selective coronary arteriography is technically difficult. The technique has been used in 13 consecutive infants and has proved very helpful in 12, with no serious adverse effects.
