What is Ventricular Septal Defect?

Also known as: VSD.

The ventricles are the lower chambers of the heart. Ordinarily, the left ventricle pumps blood out to the body, while the right ventricle pumps blood to the lungs. A wall divides the ventricles from one another. But a ventricular septal defect is a hole in this wall. This causes the blood between the two ventricles to mix, which can cause circulation problems in the body.
