About this study
Official title: A Prospective, Multicenter, Randomized Controlled Clinical Trial to Evaluate the Efficacy and Safety of Transcatheter Tricuspid Valve Clipping Systems in Patients With Severe or Greater Tricuspid Regurgitation.
The transcatheter tricuspid valve clipping system is specially designed for the treatment of tricuspid regurgitation. Under the guidance of ultrasound and DSA imaging, the investigational device is advanced into the right ventricle via a femoral or jugular venous puncture approach. The clipping component grasps the edges of the dysfunctional valve leaflets (usually unable to close properly), thereby reducing the area of the tricuspid orifice that fails to coapt normally, achieving minimally invasive treatment of tricuspid regurgitation.
- Being tested
- Experimental: Transcatheter tricuspid valve repair using the transcatheter tricuspid valve clipping system +GDMT, Guideline Directed Medical Therapy
