Systemic-to-pulmonary shunt
- Systemic-to-pulmonary shunt
A systemic-to-pulmonary shunt is a cardiac shunt which allows, or is designed to cause, blood to flow from the systemic circulation to the pulmonary circulation. This occurs when:
#there is a passage between two or more of the great vessels; "and",
#systemic pressure is higher than pulmonic pressure and/or the shunt has a one-way valvular opening.A systemic-to-pulmonary shunt functions as follows:
# left-to-right in the absence of discordance.
# right-to-left if the great vessels are d.
