Patients with isolated functional or recurrent tricuspid regurgitation are often considered high risk and denied surgery. There has been growing experience for transcatheter tricuspid valve implantation through valve-in-valve or valve-in-ring, and recently, but to a lesser extent, in native annulus. The NaviGate is a novel self-expanding valved-stent designed with unique features to treat tricuspid regurgitation, particularly, in the settings of severely dilated tricuspid annulus. Herein, we present the innovation facets and clinical application of the NaviGate system.

三尖瓣关闭不全的经导管创新：导航。

患有孤立的功能性或复发性三尖瓣关闭不全的患者通常被认为是高风险且被拒绝接受手术。通过瓣膜内瓣膜或瓣环内瓣膜经导管三尖瓣植入术的经验不断增长，最近在自然瓣环中的植入率有所下降，但程度较轻。NaviGate是一种新颖的自膨胀瓣膜支架，设计具有独特的功能，可治疗三尖瓣关闭不全，特别是在严重扩张的三尖瓣环位置。在这里，我们介绍了NaviGate系统的创新方面和临床应用。
