Comparative Study
Outcomes after the palliative arterial switch operation in neonates with single-ventricle anatomy.
Newborns with single-ventricle anatomy, transposition of the great arteries, and systemic outflow obstruction are challenging patients most often managed with a Norwood or Damus-Kaye-Stansel (DKS) procedure. The palliative arterial switch operation (pASO) offers the theoretical advantage of avoiding a systemic-to-pulmonary artery shunt physiology and posterior entrapment of the left pulmonary artery while aligning the single left ventricle with the posterior semilunar valve. Limited outcome data exist for the pASO. The purpose of this study was to examine the clinical course of patients after this operation. ⋯ The pASO should be considered in neonates with single ventricle, transposition, and systemic outflow obstruction because it affords a favorable anatomic arrangement for long-term palliation, with excellent survival and preserved ventricular function.

Multicenter Study Comparative Study
Differential case ascertainment in clinical registry versus administrative data and impact on outcomes assessment for pediatric cardiac operations.
Administrative datasets are often used to assess outcomes and quality of pediatric cardiac programs; however their accuracy regarding case ascertainment is unclear. We linked patient data (2004-2010) from the Society of Thoracic Surgeons Congenital Heart Surgery (STS-CHS) Database (clinical registry) and the Pediatric Health Information Systems (PHIS) database (administrative database) from hospitals participating in both to evaluate differential coding/classification of operations between datasets and subsequent impact on outcomes assessment. ⋯ This study demonstrates differences in case ascertainment between administrative and clinical registry data for children undergoing cardiac operations, which translated into important differences in outcomes assessment.
