What Are the Four Separate Congenital Heart Defects?

Q:

What are the four types of separate congenital heart defects?

A:

These four separate conditions together are called Tetralogy of Fallot.

Classically, there are four types of defects:

  • A ventricular septal defect, a hole between the two ventricles
  • Pulmonary stenosis, narrowing of the exit from the right ventricle
  • Right ventricular hypertrophy, enlargement of the right ventricle
  • An overriding aorta, which allows blood from both ventricles to enter the aorta

Q:

What are the causes of TOF?

A:

The cause is typically not known. But the risk factors include a mother who uses alcohol, has diabetes, is over the age of 40, or gets rubella during pregnancy. It may also be associated with Down Syndrome.
