Transposition of the great arteries with posterior aorta: detection by two-dimensional echocardiography.

Two-dimensional echocardiographic features in a case of transposition of the great arteries (TGA) with the posterior aorta are described. The unusual arrangement of the great arteries and the presence of bilateral conuses and aortic-mitral fibrous continuity were clearly demonstrated by angiocardiography and then confirmed at surgery.
