ABBOTT1 described transposition of the arterial trunks as that condition in which "the great trunks have undergone an alteration in their relative position to each other or to the ventricles from which they emerge whereby the aorta comes to lie in the path of the unaerated blood from the right ventricle." This definition includes four types of anomalies: overriding aorta; partial, or simple, transposition; complete, or crossed, transposition; mixed transposition, or transposition with atresia of the valves.
It is the purpose of this paper to present a case of complete transposition of the arterial trunks in which the aorta arose from the right ventricle and the pulmonary artery from the left ventricle.
Many theories have been advanced to explain the abnormality; these have been reviewed by Lev and Saphir.2
