Pediatric Tricuspid Atresia

Key Points About Tricuspid Atresia in Children

  • Tricuspid atresia (TA) occurs when the tricuspid valve does not develop correctly. This prevents blood flow from the right atrium to the right ventricle.
  • TA may be identified during a prenatal ultrasound or shortly after birth when the baby becomes blue (cyanotic).
  • Your child will stay in the intensive care unit (ICU).
  • Your child will need medicines and a series of surgeries to allow oxygen-rich (red) blood to be pumped to the body.
  • Your child will need to be followed by a specialist in congenital heart conditions throughout their life.
