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.
Keywords: NaviGate valved-stent; Transcatheter implantation; Tricuspid valve.
