Bicaval TricValve Implantation in Patients With Severe Tricuspid Regurgitation: 1-Year Outcomes From the TricBicaval Registry
Authors' conclusion
In this highly comorbid population with severe TR, caval valve implantation using the TricValve system led to significant 1-year clinical improvement, with mortality rates aligned with baseline TRI-SCORE.
