Objectives: This study aimed to describe the outcomes of Down syndrome patients who underwent cardiac surgery for congenital heart defects and to develop risk prediction models for in-hospital mortality, recurrent hospital admission, and the need for catheter intervention among a cohort of patients.
Methods: This single-centre retrospective cohort study included consecutive Down syndrome patients who underwent cardiac surgery for congenital heart defects between January 2018 and December 2021. We reviewed the electronic medical records.
