超声心动图引导经房间隔途径经导管二尖瓣置换术一例

Echocardiography-guided transseptal mitral valve replacement:a case report

近年来,经导管二尖瓣置换术是瓣膜介入领域的热点,这为不适合外科开胸术的二尖瓣反流患者带来了希望。该文报道了一例重度二尖瓣反流的老年女性患者,因经标准药物治疗效果不佳,在超声心动图的引导下成功使用了HighLife系统行经房间隔途径经导管二尖瓣置换术。在经导管二尖瓣置换术中,超声心动图不仅助力了手术进程,可引导导丝成环、收紧导丝、房间隔穿刺、固定环闭合、房间隔球囊扩张、人工瓣膜置入和术后即刻评估,也提高了手术的安全性,在术中发挥着十分重要的作用。

In recent years,transcatheter mitral valve replacement is a focused issue in the field of valve intervention,which brings hope to mitral regurgitation patients who are not suitable for surgical thoracotomy.This paper presents the case of echocardiography-guided transseptal mitral valve replacement with the HighLife system in an elderly female patient with severe mitral regurgitation who failed to respond to standard medical therapy.During the procedure,echocardiography was used to guide the wire looping,cinching,atrial septal puncture,ring closure,atrial septal balloon dilatation,prosthetic valve implantation and immediate postoperative evaluation.Echocardiography plays an important role in transseptal mitral valve replacement,which can help the procedural process and improve the safety of the procedure.
