A total cavopulmonary connection (Fontan surgery) is rarely performed in a child with trisomy 21 (Down syndrome) for a univentricular heart, and the outcomes after surgery are not well defined, but the incidence of mortality has been reported to be higher. To determine the mortality rate and contributing factors after Fontan surgery in children with Down syndrome, mortality data after Fontan surgery from the Pediatric Cardiac Care Consortium Registry were evaluated. Among Fontan procedures (n = 2,853), all patients with Down syndrome (n = 17) were selected, of whom 13 had hemodynamic data available. Thirteen children without chromosomal aberrations were then selected as a control group, matched 1 to 1 for gender, age, weight, lesion, and type of Fontan procedure. The following variables were evaluated: pulmonary artery pressure and vascular resistance, weight, hemoglobin, degree of atrioventricular regurgitation, previous Glenn operation, fenestration, and length of stay in the hospital. In children with Down syndrome, mortality after the Glenn operation was 28%. Mortality after the Fontan operation was increased significantly (p = 0.001) in children with Down syndrome (35%) compared with those without Down syndrome (10%). Between patients with Down syndrome and controls, there were no significant differences in the perioperative parameters evaluated. Almost all mortality was in the early postoperative period in children with Down syndrome. The relative risk ratio of mortality was 2.5 (95% confidence interval 0.63 to 10). In conclusion, Down syndrome was found to be an independent parameter associated with a significantly higher risk for mortality in the early postoperative period after Fontan surgery.
