Ventricular septum defect

Ventricular septum defect

Normally, the heart has four chambers. Two cameras are on the left and two on the right. The wall separating the left side of the right is called the septum. A defect of the ventricular septum is a hole in the wall between the two lower chambers of the heart (called ventricles). The hole allows oxygen-rich blood to be mixed from the left ventricle with oxygen-poor blood from the right ventricle.
