Abstract 14470: A Comparison Between Patent Ductus Arteriosus Stent and Modified Blalock-Taussig Shunt as Palliation for Infants With Ductal-dependent Pulmonary Blood Flow: Insights From a Multi-center Collaborative

Introduction: Infants with ductal dependent pulmonary blood flow (PBF) may undergo palliation with either ductus arteriosus stent (DAS) or Blalock-Taussig shunt (BTS). A balanced comparison of these two approaches has not been performed. Methods: Consecutive infants with ductal dependent PBF and confluent pulmonary arteries palliated with either DAS or BTS from 1/08 to 11/15 were retrospectively reviewed from the 4 member centers of the Congenital Catheterization Research Collaborative. Primary outcome was defined as death or reintervention to treat cyanosis prior to any definitive repair or next staged palliation. Secondary outcomes included: intensive care unit (ICU) and hospital length of stay (LOS), diuretic use at discharge, and procedural complications. Outcomes were compared between treatment strategies using propensity score adjustment to account for baseline differences between groups. Results: The cohort consisted of 105 DAS and 174 BTS patients. There were no differences in demographic and clin...
