Abstract

OBJECTIVE: To describe the results of surgical treatment of hypoplastic left-heart syndrome (HLHS) and HLHS-like disorders in the Amsterdam-Leiden Centre for Congenital Heart Disease, the Netherlands. DESIGN: Retrospective, descriptive. METHOD: Data were collected on 43 neonates with HLHS or similar disorders who underwent surgical treatment between December 1999 and December 2005. HLHS was present in 37 patients and 6 had disorders similar to HLHS (unbalanced atrioventricular septal defect, truncus arteriosus with hypoplastic left ventricle, double inlet left ventricle). Surgery was performed in 3 steps: Norwood operation shortly after birth (n = 43), bidirectional cavopulmonary anastomosis a few months later (n = 30) and total cavopulmonary connection at the age of 2-3 years (n = 10). During the Norwood operation, the first 21 patients received a modified Blalock shunt (between the right brachiocephalic artery and pulmonary artery), whereas the following 22 patients received a Sano shunt (between the right ventricle and pulmonary artery). RESULTS: Of the 43 patients, 11 died: 7 within 30 days of the first operation, 2 between the first and second operation, and 2 between the second and third operation. Actuarial survival for the entire group is 74% (32/43). The mortality rate was lower with the Sano shunt (9%; 2/22) than with the modified Blalock shunt (43%; 9/21). Catheter interventions were necessary in 10 patients: 6 had balloon dilatation of the distal aortic arch and 4 had balloon dilatation/stent placement for narrowed pulmonary arteries. With a median follow-up of 22 months (range: 1-75), 2 patients had marked neurological side effects. All 32 surviving patients were in good clinical condition
