From May 1977 to February 1981, 36 modified Blalock-Taussig shunts were performed in 34 patients for a variety of cyanotic congenital cardiac lesions. Microporous expanded PTFE was utilised as a conduit between the subclavian artery and the ipsilateral pulmonary artery. Graft diameter was 4 mm in 15 cases, 6 mm in 17 cases, and 8 mm in the remaining 4. ⋯ This shunt has all the advantages of the original Blalock-Taussig procedure. In addition, it preserves the integrity of the subclavian artery and minimizes the technical problems associated with the classical shunt. It is the procedure of choice at our hospital.
