Transposition of the Great Arteries Associated With Non-Kommerell Diverticulum: Lessons From Two Cases.

Vascular ring malformations usually occur as an isolated lesion. d-Transposition of the great arteries (d-TGA) associated with vascular ring malformations has seldom been reported in the literature. In this report, we describe two unusual cases of d-TGA associated with non-Kommerell diverticulum resulting in vascular ring. Our approach for the diagnosis and surgical management of this unusual combination of congenital heart lesions is described.
