Pulmonary Artery Sling


Expert Diagnosis and Care for Rare Pulmonary Artery Disease in Children


Nemours doctor checks baby for pulmonary artery sling.

Pulmonary artery sling is a rare condition where the left pulmonary artery (transports oxygen-depleted blood from the heart to the lungs) has an unusual starting place and route as it travels to the left lung. Usually, it would branch off from the main pulmonary artery. In a heart with pulmonary artery sling, it branches from the right pulmonary artery and passes between the trachea (windpipe) and esophagus (tube that carries foods and liquids from the mouth 

to the stomach). This unusual path causes pressure on the trachea and esophagus. Because of this, all children with pulmonary artery sling will require surgery. 

Pulmonary artery sling is a congenital heart defect, which means babies are born with it. At Nemours, we offer leading-edge capabilities to detect heart problems early, including babies still in the womb — giving children the best chance. If your child has been diagnosed with pulmonary artery sling, our board-certified, fellowship-trained pediatric cardiologists and cardiothoracic surgeons (specialists in surgical procedures of the chest, including the heart and lungs) will offer the latest treatment options, including advanced surgical repair techniques. The Nemours Cardiac Center teams offer the latest in research-backed care, delivered with compassion.

Services We Offer for Pulmonary Artery Sling

Services We Offer for Pulmonary Artery Sling


The expert teams in our Nemours Cardiac Center locations offer a full range of pediatric heart care to diagnose and treat pulmonary artery sling. Services vary by specialist and location, but may include:

  • Fetal Diagnostics. Early detection in our perinatology and fetal medicine centers help us diagnose some congenital heart defects and make a treatment plan for when your baby’s born. 
  • Cardiac Diagnostic Testing. State-of-the-art, noninvasive and minimally invasive tests for kids of all ages, even babies still in the womb. 
  • Cardiology. Your child’s cardiologist will help with medications and monitoring, as well as long-term treatment plans. 
  • 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. 
  • Heart Surgery. Surgical repair is needed for pulmonary artery sling and will probably be done as soon as your baby is born to position the artery and take pressure off and possibly repair the trachea or esophagus.
