Defining an Optimal Result of Transcatheter Tricuspid Valve Intervention: Results From the Tri-QOL Study

Health status improvement after TTVI was most strongly associated with the degree of TR reduction, although there was minimal additional improvement for most patients beyond a 3-grade reduction in TR. These findings support the goal of achieving mild or less TR with TTVI, although patients with torrential TR at baseline may be well served if moderate TR can be achieved.
