摘　　要：本文报道了1例单纯超声心动图引导经导管主动脉瓣置换术治疗主动脉瓣生物瓣衰败的病例。患者8年前行外科主动脉瓣生物瓣置换术,此次因生物瓣狭窄接受单纯超声心动图引导经导管主动脉瓣瓣中瓣置换治疗。本例单纯超声心动图引导瓣中瓣置换技术的成功应用,为生物瓣衰败术后再次瓣膜置换提供了新的微创治疗手段,展示了超声心动图引导介入技术在经导管主动脉瓣瓣中瓣置换技术中的可行性。同时本文还报道探讨了该介入技术在瓣膜定位、减少并发症风险及改善预后中的作用。This article reports a case of transcatheter aortic valve replacement guided by echocardiography only for the treatment of aortic valve bioprosthesis failure.The patient developed bioprosthesis stenosis eight years after surgical bioprosthetic aortic valve replacement and underwent successful transcatheter aortic valve-in-valve replacement under echocardiography guidance.This offers a new treatment option for valve replacement after bioprosthetic valve failure under echocardiography guidance,and demonstrates the feasibility of echocardiography-guided interventional transcatheter valve-in-valve replacement.Also,this report discusses the technique details in valve positioning,reducing the risk of complications and improving prognosis.
