... side effect of high shear stresses created by the design of the valves ... An ideal heart valve from an engineering perspective would produce minimal pressure drops, have small regurgitation volumes, minimize turbulence, reduce prevalence of high stresses, and not create flow ... One measure of the quality of a valve is the effective orifice area (EOA), which can be calculated as follows where is the root mean square systolic/diastolic flow ...
