WebA pulmonary shunt occurs when there is re-diversion of blood from its usual path through pulmonary circulation.This can occur when there is an abnormal flow of blood from the right side of the heart to the left side of the heart, bypassing the lungs. Examples include conditions like patent ductus arteriosus, ventricular septal defect, and atrial septal defect.
