We report an unusual association of scimitar syndrome with right diaphragmatic hernia, left-sided aortic arch with "aberrant right subclavian artery" in a 2-year-old boy who underwent stepwise transcatheter occlusion of a significant aortopulmonary collateral followed by surgical treatment for the repair of the diaphragmatic hernia and esophageal compression. (Level of Difficulty: Advanced.).
