Figure 1 :Angiograms in a 7-year-old girl with long-standing neo-left pulmonary artery occlusion (a) after an intial Norwood procedure and then subsequent bidirectional Glenn operation. Note the dimple (arrow) that helps direct the guidewire into the occluded vessel lumen. The distal left pulmonary artery is visualized with a left lower pulmonary vein wedge angiogram (b). The occluded segment was crossed using a guide and glide system and the stiff end of a 0.018" hydrophilic guidewire (c). Two Genesis XD 1910 stents (Cordis, Warren, NJ) were placed in series (mounted on 10-mm balloons) to establish vessel patency (d)
