Outcomes in Adult Congenital Heart Disease Patients With Down Syndrome Undergoing a Cardiac Surgical Procedure.

Background: As the life expectancy of patients with Down syndrome (DS) improves, the number of older patients with DS who require a cardiac surgical procedure for congenital heart disease will increase. Perioperative risk factors and outcomes in these patients are unknown.

Methods: In a multicenter retrospective study, teenaged and adult patients with DS who underwent a cardiac surgical procedure between 2008 and 2018 were matched by age and surgical procedure with patients who did not have DS.
