Early Outcomes of the Norwood Procedure in a Reference Center in Brazil.

Background: Only two papers have addressed the early outcomes of patients with hypoplastic left heart syndrome (HLHS) undergoing the Norwood operation, in Brazil.

Objectives: We evaluated patients with HLHS undergoing the first-stage Norwood operation in order to identify the predictive factors for early (within the first 30 days after surgery) and intermediate (from early survival up to the Glenn procedure) mortality.

Methods: Patients with HLHS undergoing the stage I Norwood procedure from January 2016 through April 2019, in our service, were enrolled.
