Easy Fenestration Technique for Extracardiac Fontan Operation

During an extracardiac conduit type of Fontan operation, fenestration is not always technically easy, particularly when the right atrium is small and located posteriorly. We describe here an easy technique for performing an anastomosis of a polytetrafluoroethylene ringed graft to the atrium for fenestration in the setting of an extracardiac conduit Fontan operation. The surgical technique starts with a purse string suture that is customized to fit the atrium and utilizes a ringed graft that is inserted into the right atrium through the purse string, which is then tied.
