Anomalies of the fetal aortic arch: a novel sonographic approach to in‐utero diagnosis

“…A similar incidence of 0.1% was reported in the adult population 18 . This malformation has two major variants: (i) Mirror-image branching and (ii) retroesophageal, aberrant, left subclavian artery.…”

Fetuses with right aortic arch: a multicenter cohort study and meta‐analysis

“…It courses to the right of the trachea, in contrast to the normal left aortic arch (LAA). Its incidence is estimated to be 0.1% 1,2 . Variations of aortic laterality and branching pattern result from abnormal regression of the primordial paired aortic arches during embryonic development.…”

Unilateral Pulmonary Artery Agenesis with Right Sided Aortic Arch

“…UPAA is an infrequent condition which occurs in approximately 1 in 200,000 people [1][2][3]. UPAA is relatively uncommon on the left side.…”

“…UAPA is believed to result from the involution of the proximal sixth aortic arch, thereby forgoing expected embryological fusion with the pulmonary trunk. Most common symptoms experienced include recurrent pulmonary infections, hemoptysis, and shortness of breath upon exertion [2].…”
