Differential cyanosis, meaning cyanosis and clubbing of the lower extremities with normal upper extremity nailbeds, is diagnostic of patent ductus arteriosus with pulmonary hypertension. Usually seen with dextrotransposition of the great arteries (with persistent pulmonary hypertension or aortic interruption/coarctation), it can be treated successfully with oxygen, prostaglandin E1, atrial septotomy, nitric oxide, bosentan, or extracorporeal membrane oxygenation, followed by the arterial switch operation.
