ABSTRACT

The term vascular ring refers to a group of aortic arch anomalies that compress the trachea, esophagus, or both. These malformations represent approximately 1% of all congenital heart defects and are characterized by the formation of a complete ring around the trachea and esophagus, composed of structures derived from the primitive aortic arches. Within this group is the double aortic arch, a rare condition that can be associated with various congenital heart defects. We present the case of a double aortic arch secondary to a persistent remnant of the left aortic arch, identified incidentally on computed tomography in a patient with tetralogy of Fallot.
