Early Outcomes of the Norwood Procedure in a Brazilian Reference Center, 2016-2019

80 patients with hypoplastic left heart syndrome (HLHS) underwent the stage I Norwood procedure at a Brazilian center from January 2016 through April 2019. The study by Rodrigo Freire Bezerra analyzed demographic, anatomical, and surgical data to identify predictive factors for early and intermediate mortality. The 30-day survival rate was 91.3%, and the intermediate survival rate was 81.3%.

Use Cases

• Predicting 30-day mortality risk based on patient weight, aortic valve anatomy, and postoperative ECMO need.
• Analyzing intermediate mortality risk factors related to mitral valve anatomy.
• Comparing survival rates for hypoplastic left heart syndrome surgery across different geographic regions.

Strengths

• Includes 80 patient records, described as the largest Brazilian cohort for this procedure in the recent era.
• Reports specific survival rates: 91.3% 30-day survival and 81.3% intermediate survival.
• Identifies statistically significant predictive factors (e.g., lower weight, aortic stenosis) with p-values and odds ratios.

Limitations

• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to a single reference center in Brazil.
