Atrial septal defect Left-to-Right Shunting
A left-to-right shunt is a cardiac shunt which allows, or is designed to cause, blood to flow from the left heart to the right heart. This occurs when:
- there is an opening or passage between the atria, ventricles, and/or great vessels; and,
- left heart pressure is higher than right heart pressure and/or the shunt has a one-way valvular opening.
