The heart is divided into four separate chambers. The upper chambers, or atria, are divided by a wall called the septum. An atrial septal defect (ASD) is a hole in that septum. Atrial septal defects are one of the most common heart defects seen. Find out more...

A ventricular septal defect [VSD] is a hole between the right and left pumping chambers of the heart. The heart has four chambers, a right and left upper chamber called an atrium and a right and left lower chamber called a ventricle. In the normal heart, the right and left chambers are completely separated from each other by a wall called a septum. The right atrium is separated from the left atrium by the atrial septum and the right ventricle is separated from the left ventricle by the ventricular septum. Find out more...
