Abstract
The most common pendulum valves as heart valve substitutes are the Björk-Shiley (BS) and the Lillehei-Kaster (LK) valves. Their discs are flat (Fig. 1). As has been shown by the author in earlier investigations, a disc curvature can favor the opening behavior of a pendulum valve in comparison to that of a valve with plane disc. The disadvantages of the flat disc are an incomplete opening and a strong asymmetric distribution of the flow with flow separation and a high risk of thrombus formation behind the valve ring.
