Isolation of the left subclavian artery or its anomalous origin from the pulmonary artery has been documented in several cases, especially in association with a right-sided aortic arch. However, similar anomaly involving the right subclavian artery has been less frequently reported. Isolated right subclavian artery in association with interrupted aortic arch (IAA) is extremely rare, and only three cases have been reported so far. Here, we have presented yet another case of isolated right subclavian artery associated with ventricular septal defect, type B IAA and bilateral patent ductus arteriosus.
