Anomalous origin of left subclavian artery from ascending aorta in a right aortic arch: A case report with review of literature

We present a case of an 11-year-old boy with a double-outlet right ventricle and a right-sided aortic arch showing anomalous origin of the left subclavian artery from the ascending aorta as the first branch. This case highlights the importance of knowledge of this aberrant anatomy before planning any surgical or endovascular intervention.
