Shear Stress Exposure Measurements on the Motionless Fluid Diode Valve in the Pulmonary Position

Pulmonary insufficiency is one of the consequences of congenital heart disease, and currently no permanent solution exists. The concept of a motionless diode valve to regulate the pulmonary circulation has been proposed and previously studied. The diode valve has shown the ability to regulate flow with levels of regurgitation and pressure gradient that are acceptable within the pulmonary circulation [1].
