title: Frequency and outcomes of cardiac operations and catheter interventions in Turner syndrome.
abstract: Cardiac malformations occur commonly in Turner syndrome (TS), but the outcomes of cardiac operations and catheter-based procedures are unknown. The Pediatric Cardiac Care Consortium database was queried for individuals with TS and other female subjects without genetic abnormalities or syndromes (non-TS [NTS]). Procedures for left-sided heart lesions represented most TS procedures (95.2%). Three hundred ninety-eight patients with TS who underwent 637 of these procedures of interest were compared with 25,913 female NTS subjects who underwent 56,625 procedures. The numbers of procedures per admission (1.47 vs 1.61, p = 0.01) and per patient (1.85 vs 2.16, p <0.0001) were significantly lower in patients with TS. Procedures for cyanotic heart disease other than hypoplastic left heart (HLH) were performed 4.5-fold less frequently in patients with TS. Patients with TS and NTS subjects had equivalent hospital lengths of stay, except for patients with TS who underwent hypoplastic aortic arch operations, patent ductus arteriosus ligation, pulmonary artery balloon dilation, balloon atrial septostomy, and catheter closure of atrial septal defects. There were 34 deaths among patients with TS and 1,795 among NTS subjects (8.6% vs 7.2%, p = 0.30). When HLH was excluded, mortality was lower in the TS group (3.9% vs 6.5%, p = 0.05). Operations for partial anomalous pulmonary venous connection (14.3% vs 1.9%, p = 0.03) and HLH (90.4% vs 70.5%, p = 0.08) were more likely to result in death in patients with TS. In conclusion, given generally comparable lengths of stay and numbers of procedures as well as uniformly excellent results, these data suggest that the diagnosis of TS does not increase the utilization of limited health care resources. Operations for HLH and partial anomalous pulmonary vein connection carry additional risk for those with TS. These results will permit risk stratification, prognostication, and counseling of individuals with TS and their families.
