Abstract
The investigation of the flow pattern inside artificial ventricles and downstream of heart valve prostheses gives indications to the hydrodynamic optimization of such systems. The turbulent and laminar shear stresses within show strong local variations. The degree of damage of the blood components and the wall epithel depend on the value and duration of stresses.
