In spite of the new knowledge developed in recent years surgical treatment for patients with complex forms of transposition of the great arteries remains suboptimal. This is because of the morbidity and mortality that have followed many of the corrective operations, and these are related chiefly to the basic malformation and its secondary effects. This review summarizes information about surgical treatment of such patients and comments upon some of the implications of this experience.
