A bidirectional shunt is a cardiac shunt which allows, or is designed to cause, blood to flow freely between the right heart and the left heart. This occurs when:
- there is an opening or passage between the atria, ventricles, and/or great vessels; and,
- right and left heart pressures are approximately equal.
