Figure 5
Effective orifice areas obtained by the different CMR methods (continuity equation, JSLD, and SPVT) in the in vitro study under steady flow conditions. Panels A, B, C, and D show the results obtained with an orifice of EOA of 0.48, 1.00, 1.38 and 2.11 cm2, respectively. The dashed line represents the EOA predicted by the potential flow theory (EOA = 0.61 × GOA); where GOA is the geometrical orifice area.
