Abstract 11531: Neurodevelopmental Outcomes After Neonatal Tetralogy of Fallot Repair or Palliation: Scope of The Problem and Does Treatment Strategy Matter

Summary: | IntroductionNeonates with symptomatic tetralogy of Fallot (sTOF) require early intervention with either staged repair (SR; initial palliation with subsequent complete repair) or primary repair (PR). Implications of these neonatal management strategies on late outcomes are not well understood. Thus, we aimed to assess neurodevelopmental (ND) outcomes and identify risk factors for ND concerns. MethodsFrom 2005-2017, sTOF patients who underwent neonatal intervention across 9 centers were identified. To assess ND, all living patients were sent age-appropriate parent-rating scales of executive function (Behavior Rating Inventory of Executive Function - BRIEF) and psychosocial symptoms (The Behavior Assessment System for Children, 3rd Edition - BASC-3). The results were compared by primary treatment strategy (SR vs. PR) using multivariable models. Patient and clinical factors were compared between those with normal and clinically significant abnormal results (T-score ≥60). ResultsOf 572 patients in the initial cohort, surveys were sent to 511 survivors and returned from 144 (28%, 53% male, age 3.2-15.9 years). Up to 37% of respondents had a clinically concerning score on ≥ 1 scales, including 36% with ≥1 abnormal scale present on the BRIEF and 30% with an abnormal scale on the BASC. Across SR and PR strategies, there was no difference in ND outcomes (BRIEF adjusted odds ratio (AOR) 1.55 (0.57, 4.21, p=0.39); BASC AOR 1.13 (0.43, 2.99, p=0.81)). Factors associated with clinically significant executive dysfunction included genetic syndrome (p=0.001), need for invasive ventilatory support (p=0.003) and inotropic support (p=0.01) prior to the index procedure. Only genetic syndrome (p=0.026) was associated with clinically significant psychosocial problems. ConclusionsLate ND abnormalities, specifically executive dysfunction and psychosocial concerns, are common in sTOF patients. While initial treatment strategy does not appear to have impact, intrinsic patient characteristics and pre-procedure measures of clinical severity may predict late ND outcomes and help target increased surveillance for ND complications. Forthcoming analyses will explore existing ND service utilization and parental concerns in the context of these findings. |
