Use of polytetrafluoroethylene (Gore-Tex) grafts for the construction of right ventricle-pulmonary artery conduits.

Placement of a right ventricle-pulmonary artery conduit (18- or 20-mm grafts) made of Gore-Tex without a prosthetic valve was undertaken in 6 patients ranging in age from 8 1/2 to 32 years. Three patients had tetralogy of Fallot with pulmonary atresia, and the other 3 had transposition of the great vessels, ventricular septal defect, and pulmonary obstruction. Pulmonary pressure was low in all patients. The technique for implantation of this valveless, noncrimped type of prosthesis is described.
