The case histories of 2 children who underwent repair of tricuspid atresia are reported. In the first case, the operation consisted in the partial closure of the foramen ovale through the right atrial appendage. The proximal pulmonary trunk was closed, and the pulmonary outlet was constructed by insertion of a pulmonary homograft between the right atrial appendage and the distal pulmonary trunk. In the second case, it was possible to do a direct anastomosis with the patient's own pulmonary artery. The vessel had previously been removed from the outflow tract of the right ventricle, so that there was no need of using a homograft. These techniques are presented as a means of repair in tricuspid atresia without pulmonary hypertension.
