Services We Offer

Services We Offer


We offer comprehensive services, which may vary depending upon the condition and location:

  • 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 diagnostic testing and kid-friendly imaging — state-of-the-art, noninvasive and minimally invasive tests for kids of all ages, including fetal testing for babies still in the womb
  • cardiovascular genetics counseling with a certified genetic counselor — for conditions that are caused, at least in part, by changes in genes
  • heart surgery — advanced procedures for congenital (present at birth) heart disease
  • heart transplants (available in the Delaware Valley only)
  • preventive cardiology — evaluation and guidance for kids with conditions that could put them at risk for future heart problems (such as obesity, high blood pressure, high cholesterol, diabetes and coronary artery disease)
