Clinical Trial Summary

Approximately 40,000 infants are born each year in the United States with congenital heart defects (CHD), and heart defects are the leading cause of birth defect-related deaths in the United States. While advances in surgical treatment, cardiac bypass, and post-operative management have improved mortality for children born with heart defects, these children continue to have significant morbidity related to post-operative malnutrition, multiple organ dysfunction (MODS), and sepsis. Proposed mechanisms for post-operative sepsis and MODS is via loss of intestinal epithelial barrier function (EBF) or intestinal micro biome diversity.

The purpose of this multi-center observational cohort study is to understand the extent to which practice variation for routine post-operative care might worsen intestinal barrier dysfunction and reduce diversity of the intestinal microbiome for infants undergoing surgical correction of left sided cardiac obstructive defects. We will enroll 80 children with left sided obstructive congenital cardiac lesions across several US congenital cardiac centers to obtain clinical data and biological specimens. We will leverage existing differences in nutritional and antibiotic strategies at these centers to better understand how intestinal barrier function and the intestinal microbiome may contribute to post-operative multiple organ dysfunction syndrome.
