Abstract Objective: We hypothesized that a right aortic arch in situs solitus, with or without an associated
cardiovascular malformation, is often associated with a vascular ring.
Methods: From those born in Southern Nevada between March 2012 and March 2017, we identified 50 (3.6 per 10,000 live births) with a right aortic arch and situs solitus. From the 50 patients,
6 did not meet inclusion criteria for further analysis.
Results: Of the 44 remaining, 33 (75%) had a vascular ring. Of the 33 with a vascular ring, 26
(79%) occurred with an isolated right aortic arch, and 7 (21%) had More >
