Pediatric Ventricular Septal Defect (VSD)

Key Points About Ventricular Septal Defect (VSD) in Children

  • A VSD is an opening in the dividing wall between the two lower chambers of the heart.
  • The size of the opening affects how severe your child’s symptoms are.
  • Small VSDs may close on their as your child grows. If your child has a larger VSD, he or she will likely need surgery or a cardiac catheterization to fix it.
  • Most children whose defects close on their own or who have VSD repairs will live normal, healthy lives.
