A review of animals receiving a TAH with 4 mechanical valves suggests that the least damage to the blood cell components is associated with the BS valve when compared with the MH valve at similar heart rates. Clinical anemia in varying stages was observed in most animals in this study. However, most calves compensated for the increased rate of hemolysis and none required blood transfusions. The BS valve would appear to combine minimal turbulence and mechanical crushing in a physiological setting.
一项对接受带4个机械瓣膜的全人工心脏（TAH）的动物的回顾表明，在相似心率下，与美敦力（MH）瓣膜相比，百多力（BS）瓣膜对血细胞成分的损伤最小。在本研究中，大多数动物出现了不同阶段的临床贫血。然而，大多数小牛代偿了溶血率的增加，无一需要输血。在生理环境中，BS瓣膜似乎兼具最小的湍流和机械挤压作用。
