Fig. 4B —13-year-old girl presenting with dyspnea on exertion who had undergone extracardiac Fontan operation for tricuspid atresia. Reformatted contrast-enhanced 3D maximum-intensity-projection (MIP) image shows patent extracardiac conduit (arrow) between inferior vena cava and right pulmonary artery. Superior vena cava is connected to top of right pulmonary artery (Glenn anastomosis). After total cavopulmonary anastomosis, superior vena cava flow is directed mostly to right pulmonary artery, and inferior vena cava flow, to left pulmonary artery. Due to flow dynamics after this procedure and timing of imaging acquisition, there is paucity of contrast material in inferior vena cava and extracardiac conduit resulting in low perfusion in left lung (star).
