Tetralogy of Fallot with Right Aortic Arch and Isolation of the Left Innominate Artery from a Left-Sided Patent Ductus Arteriosus

Abstract.

Isolation of the left innominate artery arising from the ductus arteriosus is a rare clinical entity with only nine cases being reported in the literature [5, 7, 8]. We describe a case consisting of tetralogy of Fallot, right aortic arch, and isolation of the left innominate artery arising from a left-sided ductus arteriosus which, to the best of our knowledge, has not been previously reported. The embryology of the aortic arch anomaly is reviewed.
