Brief 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.

Ages Eligible for Study:   up to 2 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study population will consist of infants and young children who are diagnosed with left sided obstructive congenital heart disease and are scheduled for corrective surgery. Investigators will enroll a total of 80 patients in this multi-center trial. Investigators anticipate that local enrollment will be about 1-2 patients per month, or 12-24 per year when the cardiac program is active.

Inclusion Criteria:

  • pre-operative diagnosis of left sided obstructive congenital cardiac defect

Exclusion Criteria:

  • Corrected gestational age < 37 weeks at time of surgery
  • Short bowel syndrome
  • Intestinal graft vs. host disease
  • Inflammatory Bowel Disease (Ulcerative Colitis, or Crohn's disease)
  • Candidate for intestinal transplant
  • History of necrotizing enterocolitis (NEC)
  • Previous Randomization into this study
