Early degeneration of prosthetic aortic valve in transcatheter aortic valve replacement (TAVR) is a rare complication.
We report the case of a 75-year-old woman who presented with severe calcific stenosis of Edwards SAPIEN-XT valve implanted only 4 years previously. She is a Jehovah's Witness and has background of Sjogren's syndrome with secondary cryoglobulinaemic vasculitis. She was not a suitable candidate for valve-in-valve TAVR in view of early prosthetic valve failure by calcification.
She underwent surgical explantation of the Sapiens XT valve and mechanical aortic valve replacement.
To our knowledge, this is the first time that early TAVR valve degeneration and failure of an Edwards SAPIEN-XT valve was reported which required surgical replacement with a mechanical valve.
经导管主动脉瓣置换术（TAVR）中人工主动脉瓣的早期退变是一种罕见的并发症。
我们报告了一例75岁女性的病例，她仅在4年前植入的爱德华SAPIEN-XT瓣膜出现严重钙化狭窄。她是一名耶和华见证人，有干燥综合征伴继发性冷球蛋白血症性血管炎病史。鉴于人工瓣膜早期钙化失败，她不适合进行瓣中瓣TAVR。
她接受了Sapiens XT瓣膜的手术取出并进行了机械主动脉瓣置换。
据我们所知，这是首次报道爱德华SAPIEN-XT瓣膜早期TAVR瓣膜退变及失败，且需要用机械瓣膜进行手术置换。
