摘　　要：经导管主动脉瓣置换术(TAVR)已成为重度主动脉瓣狭窄的重要治疗方法。但TAVR相关并发症仍不能忽视,其中急性肾损伤(AKI)是常见的并发症,使用对比剂是其重要原因。为探索降低AKI发生的方法,本文报道了两例单纯超声心动图引导下行TAVR成功治疗重度主动脉瓣狭窄的病例,患者分别为75、69岁老年女性,均置入26 mm Evolute Pro瓣膜(美敦力,美国),术后超声心动图显示瓣膜位置、功能良好。Transcatheter aortic valve replacement(TAVR)has become an important therapeutic approach for severe aortic stenosis.However,complications associated with TAVR cannot be overlooked,among which contrast agents induced acute kidney injury(AKI)is a common complication.To explore methods to reduce the occurrence of AKI,this article reports two cases of successful treatment of severe aortic stenosis by TAVR under pure echocardiographic guidance,both of whom were elderly women aged 75 and 69,respectively,and both were implanted with a Evolute Pro 26 mm valve.Postoperative echocardiography showed good valve positioning and function.
