Hydraulic characteristics of heart valve bioprostheses mounted on supporting structures of various rigidity have been studied under physiologic conditions. An actual mobility of the supporting structures made of different polymers is determined. Static and dynamic components of the support displacements have been shown to develop as the bioprosthesis is under the load, the dynamic component being strongly dependent upon the rigidity of fastening the bioprosthesis on the axis. It is noted that considerable improvements in hydraulic characteristics of bioprostheses are achieved through the use of flexible supporting structures.
在生理条件下，对安装在不同刚度支撑结构上的心脏瓣膜生物假体的水力特性进行了研究。确定了由不同聚合物制成的支撑结构的实际可移动性。研究表明，当生物假体承受负荷时，支撑位移的静态和动态分量会出现，动态分量强烈依赖于生物假体在轴向上固定的刚度。值得注意的是，通过使用柔性支撑结构，生物假体的水力特性有了显著改善。
