Ten patients underwent an aortapulmonary artery shunt with a polytetrafluoroethylene (PTFE) tube between December, 1976, and October, 1977. Five of them were less than 1 month old. The diameter of the PTFE tube was 5 mm in 9 patients and 4 mm in 1 patient. ⋯ In our institution, the Blalock-Taussig shunt is the procedure of choice. The PTFE shunt is used when the anatomy of a patient is unsuitable for a Blalock-Taussig shunt. A tube diameter of 5 mm is optimal for infants when further growth is considered, even if digitalization is necessary to control congestive heart failure.
