[Total correction of truncus arteriosus with severe truncal valve insufficiency in neonate]

The prognosis of infants with truncus arteriosus associated with severe truncal valve insufficiency is quite poor. Total correction was successfully performed in a neonate with such a complicated anomaly. The patient was 21 days old female with anuria due to severe congestive heart failure preoperatively in spite of medical treatment. She underwent Rastelli operation and pulmonary artery was reconstructed using autologous pericardial 3 valved conduit. Truncal valve was 4 cusps with the malformed nodular margins and one cusp had cleft. This cleft was closed suturing the cleft cusp and adjacent cusp each other and annuloplasty was added in 4 commissures. She survived and her truncal valve insufficiency was still mild at 2 years post-operative period. Although total correction with truncal valve repair for such a severely ill neonate and young infant with truncus arteriosus as this patient has not been reported, our experience suggests that severe truncal valve insufficiency could be fairly well repaired by valvulo-annuloplasty.
