From 1957 through September, 1983, 35 @entity1 with @entity215 and @entity338 underwent operation. Two subgroups of @entity1 were recognized: minimally symptomatic (Group A, n = 21) and markedly symptomatic (Group B, n = 14). Group B @entity1 were symptomatic at an earlier age and were younger at operation. Ages ranged from 1 day to 42 years (mean = 7.8 +/- 7.4 SD). Repair consisted of closure of the @entity1757 and relief of the right ventricle-pulmonary artery pressure gradient (nine @entity1 received a tissue valve). In five @entity1 , partial resection and/or plication of the @entity438 also was performed. Operative mortality was 4.8% in Group A and 35.7% in Group B. In up to 25 years of follow-up, there was one late death in Group A (an early case with complete @entity616 ); the remaining 19 @entity1 are asymptomatic. In Group B, there were four late deaths, three related to @entity1887 . These results indicate @entity338 is tolerated well in minimally symptomatic @entity1 . For markedly symptomatic @entity1 , results may be improved if repair includes @entity340 and reduction of size and length of @entity438 .
