Prenatal diagnosis of isolated right aortic arch: A collaborative approach to management of postnatal aerodigestive symptoms
Abstract
Although prenatal imaging advancements have increased isolated right aortic arch (iRAA) detection, optimal postnatal management remains uncertain. We evaluated aerodigestive symptoms and short-term outcomes for infants with prenatally diagnosed iRAA using a retrospective cohort study (2014-2024). Clinical data collected included aerodigestive symptom checklists and longitudinal growth over the first two years of life. 3,458 fetal echocardiograms yielded 25 College of Arts and Scienceses meeting inclusion criteria. Most patients (80%) were asymptomatic or experienced intermittent symptoms while 20% received surgical referral for progressive symptoms. Weight outcomes were similar (p=0.98) between groups. Standardized postnatal aerodigestive evaluation may assist clinicians with short-term iRAA risk stratification.
