An 82-year-old woman had a history of mitral valve replacement with a 25-mm MOSAIC (Medtronic, USA) for severe mitral regurgitation (MR) 8 years previously. Recently, she developed heart failure due to MR secondary to prosthetic valve failure. She underwent transcatheter valve-in-valve implantation with a 23-mm SAPIEN XT (Edwards Lifesciences, USA) to the prosthetic mitral valve by transapical approach. To our knowledge, this is the first reported case of transcatheter valve implantation for failed mitral prosthetic valve using valve-in-valve technique in Japan.
一名82岁女性8年前因严重二尖瓣反流（MR）接受了二尖瓣置换术，植入了一枚25毫米的美敦力（美国）MOSAIC人工瓣膜。最近，她因人工瓣膜功能衰竭继发MR而出现心力衰竭。她通过经心尖途径，在人工二尖瓣上植入了一枚23毫米的爱德华生命科学公司（美国）SAPIEN XT经导管瓣膜。据我们所知，这是日本首例报道的使用瓣中瓣技术对失败的二尖瓣人工瓣膜进行经导管瓣膜植入的病例。
