(rollover to compare with normal) What Is It?

In this defect, the muscle wall that separates the right and left ventricles (ventricular septum), is much thicker than normal. In some cases, the ventricular septum may be as much as 4 times the normal thickness. This is a rare defect that may run in families and affects girls and boys equally.
