Harvest of the aortic valve with intact commissure. (A) Harvest of the pulmonary autograft. (B) Harvest of the native aortic valve. (C to E) Implantation of the aortic autograft in the pulmonary position using the freehand technique. After the autograft is sewn in position, the wall of the neopulmonary artery is completed using a polytetrafluoroethylene patch. (F to I) Construction of the composite aortic autograft.
