Interrupted Aortic Arch


Early Diagnosis and Expert Repair for IAA


Mother and young child with Interrupted Aortic Arch play with blocks.

Interrupted aortic arch (IAA) is a rare, congenital (present at birth) heart condition that happens when the aorta (the blood vessel that carries blood from the heart to the rest of the body) does not form completely when a baby is developing in their mother’s womb. All babies born with IAA will need heart surgery soon after they’re born. At Nemours Cardiac Center, we offer leading-edge capabilities to detect heart problems early using fetal cardiac

diagnostics. Our board-certified, fellowship-trained pediatric cardiologists and cardiothoracic surgeons (specialists in surgical procedures of the chest, including the heart and lungs) are here to answer your questions, address your concerns, and help with treatment plans. Our cardiac teams offer the latest in research-backed care, delivered with compassion.

Services We Offer for Interrupted Aortic Arch


The expert teams in our Nemours Cardiac Center locations offer a full range of pediatric heart care for IAA and related heart defects. Services vary by specialist and location, but may include:

  • Fetal Diagnostics. Early detection in our perinatology and fetal medicine centers help us diagnose congenital heart defects like IAA as early as possible, and make a treatment plan for when your baby’s born. 
  • Cardiac Catheterization. A procedure used to diagnose or treat cardiac problems by inserting a thin plastic, flexible tube (called a “catheter”) into an artery or vein, and threading it through the bloodstream into the heart and its large blood vessels. 
  • Cardiac Diagnostics and Kid-Friendly Imaging. State-of-the-art, noninvasive and minimally invasive tests for kids of all ages. 
  • Cardiology. Your baby’s cardiologist will use medications like prostaglandin right away, and after surgical repair will work with your family to monitor your child and create a coordinated treatment plan.  
  • Cardiovascular Genetics Counseling. For conditions like IAA that may be caused, at least in part, by changes in genes. 
  • ECMO. Also known as extracorporeal life support or “ECLS,” this treats serious problems, using the technology to give hearts and lungs a chance to rest and heal.
  • Heart Surgery. All babies with IAA will need surgery, probably within a few days after they’re born. Our pediatric heart surgeons have the experience, skills and advanced technology required to provide swift diagnosis and repair in children of all ages, even the tiniest newborns.
