Fascia lata composite graft for right ventricular outflow tract and pulmonary artery reconstruction. Surgical technique.

Because there is no `ideal' method for the complete correction of some of the more complex congenital cardiac abnormalities, a technique of making a composite graft of autologous fascia lata has been developed. Three types of grafts are described, all of them being based on the same general principle. The composite graft comprises a conduit, which serves to enlarge or reconstruct the outflow tract of the right ventricle and the main pulmonary artery, and an inner valve attached inside it, which provides the conduit with a one-way flow mechanism. The technique of preparing these composite grafts is outlined and the surgical implantation of the grafts in the right ventricular outflow is described. Since November 1969, fascia lata composite grafts have been used in 18 patients with a variety of complex congenital heart malformations with very good early results.
