Figure 1
A, The inferior vena cava has been divided and the right atrial stump is sutured to the left lateral aspect of the cava. The gap behind the right atrium has been closed to develop the Fontan pathway floor. B, The inferior edge of the open right pulmonary artery is sutured to posterior mediastinum and left atrial dome. C, A portion of the opened PTFE conduit has been sutured to the anterior inferior vena cava and laterally to the pericardium. A dilator confirms adequate size. D, The finished extracardiac lateral tunnel with the final edge of PTFE sutured to the right atrial wall. PTFE, Polytetrafluoroethylene; FF, Fontan floor; LPA, left pulmonary artery; RPA, right pulmonary artery; IVC, inferior vena cava; ECLT, extracardiac lateral tunnel.
