Left-to-right shunt

Left-to-right shunt

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. [DorlandsDict|seven/000096615|left-to-right shunt]

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.
