Interrupted right-sided aortic arch.

Incomplete development of a right-sided interrupted aortic arch has not, to our knowledge, been recorded in the literature. We present a case of a 6-day-old neonate delivered at 37 weeks' gestation with an incomplete right-sided aortic arch. The anomaly was repaired with a 1-step surgical approach and the patient was discharged from the hospital. We propose a classification system for right-sided interrupted aortic arch based on that of the more common left-sided interruption.
