We here report the case of a stenosis of the CoreValve system due to reduced mobility of prosthesis cusps for which a surgical replacement of the aortic valve was proposed. The exact mechanism leading to this impaired mobility of the leaflets is yet to be determined. We also underline the fact a transcatheter aortic valve implantation (TAVI) device can be replaced by a surgical replacement without excessive operative risks despite the patient being initially considered as high-risk.
我们在此报告一例因人工瓣膜瓣叶活动度降低导致CoreValve系统狭窄的病例,针对该病例建议进行主动脉瓣手术置换。导致瓣叶活动度受损的确切机制尚待确定。我们还强调了这样一个事实,尽管该患者最初被认为是高风险患者,但经导管主动脉瓣植入术(TAVI)装置可以被手术置换所替代,且不会有过高的手术风险。
