Pulmonary-to-systemic shunt
Pulmonary-to-systemic shunt (pronunciation: pul-mon-ary to sis-tem-ic shunt) is a medical term that refers to a condition where the blood bypasses the lungs and goes directly into the systemic circulation. This can occur due to various congenital heart defects or lung diseases.
Etymology
The term is derived from the Latin pulmonarius (pertaining to the lungs), the Greek systema (whole compounded of several parts), and the Middle English shunten (to flinch or shy away).
