    Abstract:
    One hundred nine consecutive patients underent 115 palliative shunts between 1971 and 1979 for the initial management of symptomatic tetralogy of Fallot. A single Blalock-Taussig shunt was done in 78 patients, including 38 infants below 12 months of age, with two deaths (2.5% mortality rate). Thirty-two patients underwent a Waterston shunt, with one death (3.1% mortality rate). The total early shunt mortality rate was 2.7% (three deaths among 109 patients). There was one later noncardiac death and one instance of nonfatal brain abscess between the two stages. Fifty-nine of the previously shunted patients have undergone total correction at a mean postshunt interval of 37.1 months, with one early postoperative death (1.6% mortality rate). The mean patient age at total repair was 4.8 years. The two-stage combined operative mortality rate was 3.6% (four deaths among 109 patients). The Waterston shunt is considered undesirable because it complicated the total repair and was associated with a high incidence of residual right pulmonary artery obstruction at postoperative cardiac catheterization. The Blalock-Taussig shunt had a low mortality rate, high long-term patency rate, absence of interval complications, and no adverse effect at the time of total correction. It is considered the shunt of choice in all symptomatic infants and small children with tetralogy of Fallot. Our experience suggests that, at the present time, the two-stage surgical approach compares favorably with primary total correction, especially in infants under 1 year of age.
