What is a right aortic arch and what conditions is it associated with?

A right aortic arch is an anatomical variation where the aorta arches to the right of the trachea instead of the left. This pattern can occur on its own (isolated) or be part of a vascular ring when paired with other vessels in a way that can encircle and sometimes compress the trachea or esophagus. It can also be associated with other congenital heart diseases, but many cases are isolated and asymptomatic. Therefore, describing it as a right-sided aortic arch that may be isolated or associated with vascular rings or other congenital heart disease best captures both the anatomical finding and the range of possible associations.
