The corrected transposition of the great arteries with pulmonary stenosis was completely repaired in a 5 1/2-year-old boy. To relieve the stenosis of the pulmonary valve ring which was located posterior to the aorta and heart chambers, the valve-bearing tube-graft made of the pericardium was implanted as a bypass graft between the right-sided ventricle and the pulmonary trunk. Postoperative hemodynamics and cineangiographic findings were satisfactory. The use of the viable autologous tissue such as the pericardium is definitely more advantageous than that of the other homografts, since the former requires neither sterilization nor long-term preservation.
