Early Feasibility of 'Pivot Extend' for Tricuspid Regurgitation Treatment

Recruiting now · Not applicable

Conditions studied: Tricuspid Regurgitation (TR)

In brief

This clinical trial aims to evaluate the safety and demonstrate the efficacy of treatment to improve tricuspid regurgitation (TR) symptoms in patients with severe and clinically symptomatic TR through long-term implantation of an investigational medical device. 1. Determine the safety of long-term implantation of the investigational medical device "Pivot Extend" by monitoring for MACEs associated with the investigational medical device or procedure that may occur with long-term associated with the investigational medical device or procedure that may occur with long-term implantation. 2. Device success, procedural success, and clinical outcomes of long-term implantation of the investigational medical device "Pivot Extend" will be monitored.

Those with a coexisting condition, which most likely limits the participant´s life expectancy to less than one year.
Those with a preexisting pulmonary valve prosthesis or RV to PA conduit.
Those with clinical findings other than the above that, in the opinion of the investigator, are medically inappropriate for this clinical trial
