This report deals with a rare complication of disc-valve prosthesis in the mitral area. A significant disc poppet and struts destruction of mitral Beall valve prostheses occurred 20 and 17 months after implantation. The resulting valve incompetence in the first case contributed to the death of the patient. The durability of Teflon prosthetic valves appears to be in question and this type of valve probably will be unacceptable if there is an increasing number of disc-valve variance in the future.
本报告涉及二尖瓣区域碟瓣假体的一种罕见并发症。二尖瓣Beall瓣假体植入20个月和17个月后，碟片提动头及支柱出现显著破坏。在第一例中，由此导致的瓣膜功能不全致使患者死亡。聚四氟乙烯人工瓣膜的耐用性似乎存在问题，如果未来碟瓣差异数量不断增加，这种类型的瓣膜可能将无法接受。
