The Medtronic-Hall valve was developed to improve on existing tilting disc valves by reducing the risk of valvular thrombosis. This was to be accomplished by improving the hemodynamics and by allowing the disc to move downstream away from the orifice during opening. The valve was also designed for maximal structural durability to minimize the risk of mechanical breakage. With more than 1,000 Medtronic-Hall valves implanted since 1977, the clinical results have been very encouraging. The rates of thromboembolism and thrombosis are low, there have been no mechanical failures and the hemodynamic function, especially with the smaller valves, is excellent.
美敦力-霍尔瓣膜的研发旨在通过降低瓣膜血栓形成风险来改进现有的倾斜盘式瓣膜。这将通过改善血液动力学以及在瓣膜打开时使盘片向下游远离孔口移动来实现。该瓣膜还设计为具有最大的结构耐用性，以尽量减少机械破损的风险。自1977年以来已植入了1000多个美敦力-霍尔瓣膜，临床结果非常令人鼓舞。血栓栓塞和血栓形成的发生率很低，没有出现机械故障，血液动力学功能，尤其是较小瓣膜的血液动力学功能非常出色。
