Heart and Blood Conditions
Ventricular Septal Defect
What is ventricular septal defect?
Babies born with ventricular (pronounced ven-TRIH-ku-lar) septal defect (VSD) have a hole in the wall of their heart between the two lower chambers (right and left
s) where the blood leaves the heart. This wall is the ventricular septum.
Blood comes from the body into the right
. Then it flows into the right ventricle. The right ventricle pumps it to the lungs to get oxygen. Next, blood travels from the lungs to the left atrium. Then it flows into the left ventricle, which pumps it out to the rest of the body.
Normally, blood cannot pass between the ventricles. But when there is a hole between the sides of the heart, some oxygen-rich blood leaks from the left ventricle into the right ventricle and goes back to the lungs.
The hole may be small and cause no symptoms, or it may be large and cause serious problems with blood flow. If the hole is large, too much blood will be pumped to the lungs, leading to
congestive heart failure
Also, the heart will have to work harder to pump blood to the body. As a result of the extra work, the heart can get bigger.
Ventricular Septal Defect in Children
VSD is the most common heart birth defect. About 3 in every 1,000 babies has it.
VSD is often referred to as a hole in the heart. It happens early in the baby's development when the heart is forming.
Some children with VSD have other heart defects, like
atrial septal defect
. Some have other genetic conditions that increase the risk for VSD, like Down syndrome.

has extensive experience with the
patients may require for VSD, including using
to place a device that closes the hole in the septum, doing
