OBJECTIVES: Management strategy for pulmonary atresia with intact ventricular septum is controversial. We treated patients with this anomaly according to a management protocol based on our quantitative assessment of right ventricular morphology (index of right ventricular development and right ventricle-tricuspid valve index). In the present study, we reviewed a 20-year experience of the surgical treatment at our institution to define guidelines for selecting the appropriate type of surgical procedure. METHODS: Between April 1981 and June 2002, 45 consecutive patients with pulmonary atresia with intact ventricular septum underwent surgical treatment. Open transpulmonary valvotomy was performed in 27 patients and Blalock-Taussig shunt in 18 patients as the initial palliative procedure. Three patients who underwent a successful transpulmonary valvotomy alone in the neonatal period required no further operation. Definitive repair was performed in 32 patients. Biventricular repair was performed on 19 patients, one and a half ventricular repair in 3, and Fontan-type operation in 10. RESULTS: There were 1 early and 2 late deaths before the definitive operation in patients who underwent transpulmonary valvotomy. Two patients who had coronary artery interruption died 3 months and 13 years after the initial Blalock-Taussig shunt. There were 1 early and 2 late deaths after the definitive operation. Actuarial survival, including noncardiac death, was 91.1% at 5 years after the initial procedure and 81.5% at 10 years. CONCLUSIONS: We treated patients with pulmonary atresia with intact ventricular septum according to a management protocol based on our quantitative assessment of right ventricular morphology with good results.
