A review of the in vivo and in vitro fluid dynamic performance of three bioprosthetic heart valves is presented. Data on Hancock porcine valves (standard models 242 aortic and 342 mitral and modified orifice model 250 aortic), Carpentier-Edwards porcine valves (model 2625 aortic and 6625 mitral), and the Ionescu-Shiley pericardial valve are reviewed. These valves were chosen because of their past or present popularity in clinical use and because of the variation in fluid dynamic performance reported by different investigators. The flow parameters that are reported include in vivo and in vitro mean pressure drop, cardiac output or cardiac index, regurgitant volume, effective orifice area, and performance index. These data provide a framework for differentiation of normal and abnormal bioprosthetic valve function.
本文综述了三种生物人工心脏瓣膜的体内和体外流体动力学性能。回顾了汉考克猪瓣膜（标准型号242主动脉瓣和342二尖瓣以及改良孔口型号250主动脉瓣）、卡朋蒂埃 - 爱德华兹猪瓣膜（型号2625主动脉瓣和6625二尖瓣）以及伊奥内斯库 - 希利心包瓣膜的数据。选择这些瓣膜是因为它们过去或现在在临床使用中很受欢迎，以及不同研究者报告的流体动力学性能存在差异。所报告的血流参数包括体内和体外平均压力降、心输出量或心指数、反流体积、有效孔口面积和性能指数。这些数据为区分正常和异常生物人工瓣膜功能提供了一个框架。
