We present a rare case of atrial septal defect and ventricular septal defect with a vascular ring. The ring was formed by a right-sided aortic arch with an aberrant left subclavian artery that gave rise to a patent ductus arteriosus connecting to the main pulmonary artery. We performed a single-stage repair of the intra-cardiac defects and division of vascular ring with a novel sternotomy approach instead of the traditionally practised dual approach. Our novel approach included implantation of the aberrant left subclavian artery to the left carotid artery after transection. We could perform single-stage division of vascular ring along with the closure of both septal defects.
