What are the symptoms of a ventricular septal defect?

The size of the ventricular septal defect (VSD) affects the type of symptoms, severity of symptoms and the age at which they first occur. Symptoms often occur in infancy and may include:

  • fatigue
  • sweating
  • rapid breathing
  • heavy breathing
  • congested breathing
  • disinterest in feeding, or tiring while feeding
  • poor weight gain

What are the causes of a ventricular septal defect (VSD)?

A VSD occurs during a baby’s development when the opening between the lower two heart chambers does not close properly. Most ventricular septal defects occur by chance, with no clear reason.
