Figure 6: (A) AP projection - long tubular ductus arteriosus arising from the innominate/left subclavian artery with a sharp curve distally. Very tight constriction is seen at pulmonary insertion. Ductal stenting via femoral artery route. (B) 4-F long sheath is positioned in the innominate artery. 0.014 guidewire anchored in a distal pulmonary artery branch. The fi rst stent is covering the distal two-thirds of the ductus and is ready for expansion. (C) First stent is expanded (arrow). Second shorter stent is covering the remainder of the ductus and is ready for expansion. (D) Both stents after expansion are seen covering almost the entire length of ductus. A single, long stent is likely have a great diffi culty tracking over the wire and when fully expanded may cause distortion of the pulmonary artery
