During the last 12 years, 37 infants under three months of age have undergone systemic to pulmonary artery shunt for cyanotic congenital heart disease. The procedures were : Blalock-Taussig shunt (15), Waterston shunt (14), modified Blalock-Taussig shunt interposing a 5mm EPTFE graft between the divided subclavian artery and the pulmonary artery (3), modified Waterston shunt interposing a 4 mm EPTFE graft between the ascending aorta and the right pulmonary artery (5). There was no death in 10 infants who have undergone Black-Taussig shunt during the last three years. An excellent palliation has been achieved in eight of these patients for 8 to 27 months postoperatively. Of three patients with modified Blalock-Taussig shunt, two required an additional shunting operation for inadequacy of shunt after 13 to 18 months and in one patient an excellent palliation has been achieved for 35 months. Six of 14 infants with Waterston shunt were the long range survivors with an excellent palliation for more than four years. In five patients with modified Waterston shunt, there were two late deaths (not shunt related) but an excellent palliation has been achieved in three patients for 10 to 42 months. Our experience provided a conclusion that the modified Blalock-Taussig or Waterston shunt using an EPTFE graft is an effective and safe procedure when the classical shunt procedure is not feasible but the period of palliation provided by these modified procedures is relatively shorter than by the classical operation.
