Major adverse events following over-shunting are associated with worse outcomes than major adverse events after a blocked systemic-to-pulmonary artery shunt procedure

Abstract

Objectives: Causes of major adverse event after systemic-to-pulmonary shunt procedure are usually shunt occlusion or over-shunting. Outcomes categorized on the basis of these causes will be helpful both for quality improvement and prognostication. Design: Retrospective cohort analysis of children who underwent a systemic-to-pulmonary shunt after excluding those who had it for Norwood or Damus-Kaye-Stansel procedure. Setting: The Royal Children's Hospital, Melbourne, VIC, Australia. Patients: From 2008 to 2015, 201 children who had a systemic-to-pulmonary shunt were included. Interventions: Major adverse event is defined as one or more of cardiac arrest, chest reopening, or requirement for ex..
