Mitral Valve Disease


Expert, Gentle Care for Congenital Mitral Valve Defects

The mitral valve separates the two left chambers of the heart and includes two leaflets (thin, mobile flaps) that function like doors that open and close with each contraction of the heart. Among the group of mitral valve defects are two congenital (present at birth) conditions that can affect the mitral valve’s function: it’s either too loose (mitral insufficiency) or too tight (mitral stenosis). Some babies born with mitral valve disease may need surgery, and some may not need 

surgery at all — or won’t need it until they are a bit older. 

At Nemours Cardiac Center, we offer leading-edge capabilities to detect heart problems early. If your baby has been diagnosed with any type of congenital mitral valve defect, 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 for today, and the longer term. Our cardiac teams offer the latest in research-backed care, delivered within a family-centered setting.

Services We Offer for Mitral Valve Disease


The expert teams in our Nemours Cardiac Center locations offer a full range of pediatric heart care for mitral valve and other types of congenital heart disease. Services vary by specialist and location, but may include:

  • 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, even babies still in the womb. 
  • Cardiology. Your baby’s cardiologist will work with your family to monitor your child and create a coordinated treatment plan.  
  • Cardiovascular Genetics Counseling. For conditions that may be caused, at least in part, by changes in genes. 
  • Dentistry. Good dental hygiene can help prevent infection if your child has mitral valve disease. 
  • Heart Surgery. In some cases, babies with mitral valve disease will need surgery 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.
