WebA shunt is an abnormal communication between the right and left sides of the heart or between the systemic and pulmonary vessels, allowing blood to flow directly from one circulatory system to the other. A right-to-left shunt allows deoxygenated systemic venous blood to bypass the lungs and return to the body. WebA shunting lesion is one in which blood flows from one circulation to the other (most commonly the systemic to pulmonary arterial circulation) in the atrium, ventricle, arterial or venous circulation. The physiology depends upon the location of shunting. Atrial level …
