Babies born with a functional single ventricle heart and systemic outflow tract obstruction may require a Norwood (NW) procedure as the first of three staged procedures to obtain a Fontan circulation. This procedure and the following treatment pathway are associated with significant mortality. Risk factors for the Norwood procedure and the subsequent pathway are not necessarily the same. To identify these factors within New Zealand, the collective experience with the Norwood procedure was examined.Charts from 133 New Zealand children undergoing Norwood procedure from 1992 to 2014 were examined. Deaths were assigned as "early" (30-day or in-hospital) or "late" (based on timeframe from the Norwood procedure). Cardiac anatomic, patient demographic and surgery related variables were examined. Important risk factors were identified using univariate and multivariate analysis. Kaplan-Meier survival curves were calculated.Survival following the Norwood procedure was 83
