Abstract

Background: The purpose of this study was to describe the experience with staged surgical reconstruction of the hypoplastic left heart syndrome (HLHS) with a right ventricle to pulmonary artery conduit and to identify the risk factors that influence late outcome. Methods: Between February 1998 and June 2007, 62 patients with HLHS underwent a Norwood procedure by using right ventricle to pulmonary artery conduit (median age, 9 days [range, 1 to 57]; median body weight 2.7 kg [range, 1.6 to 3.9 kg]). The subsequent 47 patients underwent a bidirectional Glenn procedure (stage 2). Thirty-two patients underwent a modified Fontan procedure (stage 3). Follow-up was complete (median, 32 months; range, 1 to 101). Results: Hospital mortality after the Norwood procedure was 8% (5 of 62 patients). Between stages, 9 patients died, 3 before stage 2 and 6 before stage 3. There was 1 late death after stage 3. Overall survival was 76% (47 of 62). The estimated 1-year and and 5-year survival rates were 80% and 73%, respectively. Using the any-mortality as the endpoint, prematurity (gestational age
