Tricuspid atresia: results of treatment in 160 children

Abstract

Experience in managing 160 patients with tricuspid atresia is reviewed. The majority of these children require operative treatment in the 1st year of life. Clinical management of this rather complex anomaly is simplified by classifying each child according to total pulmonary blood flow. An overall plan of management for patients with decreased pulmonary flow is suggested. This consists of a Potts shunt as an initial procedure, limiting its anastomotic growth so that pulmonary flow becomes inadequate at age 10 to 12 years. A Glenn anastomosis is then constructed as the second procedue. The Fontan procedure should be considered carefully as an alternative to the Glenn anastomosis in these older children. Children with increased pulmonary blood flow and transposition of the great arteries are likely to require pulmonary arterial banding in infancy. Otherwise, patients in this smaller group are managed with the same overall plan. Results of long-term palliation have been good.
