摘要 目的： 探讨在心脏不停跳下保留二尖瓣结构的二尖瓣替换术临床应用价值。方法： 对1994年7月至1997年12月在浅低温体外循环心脏不停跳下对15例患者行保留二尖瓣结构的二尖瓣替换术并与同期不保留二尖瓣结构的12例比较。结果： 术后病情较稳定，心功能恢复较快，全部存活出院。两组相比，保留组SVI、EF改善明显，左房、左室缩小显著。结论： 在二尖瓣替换术中保留二尖瓣结构有维持左心室舒缩功能作用；在浅低温体外循环心脏不停跳下手术不存在心脏停跳后再灌注问题，起到减轻心脏损伤的作用，能及时发现和纠正由于手术引起的人工瓣膜的功能障碍。

Abstract Objective: To prope into theclinical value of mitral valve replacement by reserving the structures of valve with heartbeating.Methods: From July,1994 to December,1997,we had 15 cases of valvereplacement with valve structure reserved and 12 cases without in low hypothermia andextracorporeal circulation with heart beating.Results: All these patients'conditions were stable and rescoverel soon after operations.SVI & EF of thereservation group improved more obviously than the non-reservation group.Conclusion: It'suseful to keep the function of left ventricle of heart during mitral valve replacement,andthere was no problem in re-perfusion injury.It could reduce the cardiac injury and help todetect and correct the functional disorder of prosthetic valve.
