经股动脉球囊扩张式主动脉瓣置换术的初步经验

Aortic valve replacement via transfemoral balloon dilation: an initial experience

目的探讨经股动脉球囊扩张式主动脉瓣置换术治疗严重主动脉瓣狭窄患者的可行性。方法选取3例严重主动脉瓣钙化狭窄的患者,术前评估无法耐受传统开放手术,行经股动脉球扩式主动脉瓣置换术。结果 3例均经股动脉完成,其中1例经心尖穿刺辅助完成。3例手术全部成功,术后患者主动脉瓣功能显著改善,无并发症,无死亡。结论经股动脉球扩式主动脉瓣置换术可用于国人严重主动脉瓣狭窄患者,但在术前准备与评估、术中操作等方面提出了更高的要求。

Objective To discuss the feasibility of treating patients with severe aortic valve stenosis by aortic valve replacement via transfemoral balloon dilation.Methods Three patients with severe aortic valve stenosis,who could not tolerate traditional open surgery,were chosen to receive aortic valve replacement via transfemoral balloon dilation.Results All the three operations were successfully done by transfemoral approach,including one assisted by transapical puncture.The aortic valve function of patients was improved,and there was no related complication or death.Conclusion Aortic valve replacement via transfemoral balloon dilation can be used for treatment of Chinese patients with severe aortic valve stenosis;but which demands more detailed preoperative preparation,evaluation,and surgical manipulation.
