Total correction of transposition of the great arteries and left ventricular outflow tract obstruction has become feasible in recent years. Certain modifications are needed, however, to improve the long term function of the valved conduit required in the procedure. A stented porcine xenograft valve, sutured into a woven Dacron tubular graft, was used successfully in the total correction of such a malfunction. The patient described is the first so treated at the Henry Ford Hospital. The main advantage of this technique is its practicality. Both Dacron tubular grafts and stented porcine xenograft valves are commercially available. This approach is applicable also in the repair of congenital cardiac malformations which have discontinuity between the right ventricle and the pulmonary artery.
