Key result
TricValve implantation improved NYHA class and prevented rehospitalization at 8 months in a severe TR case.
Why the study?
Severe tricuspid regurgitation carries a poor prognosis and conventional surgery poses high risk in elderly patients with comorbidities, leaving transcatheter alternatives under evaluation in complex anatomy.
Does endovascular TricValve implantation improve symptoms and reduce rehospitalizations in a high-risk patient with severe tricuspid regurgitation and multiple pacemaker leads?
Does endovascular TricValve implantation improve symptoms and reduce rehospitalizations in a high-risk patient with severe tricuspid regurgitation and multiple pacemaker leads?
Transcatheter heterotopic bicaval valve implantation (TricValve) can be successfully performed and provide meaningful symptomatic relief in high-risk patients with severe tricuspid regurgitation and complex right-sided anatomy, including multiple pacing leads.

May warrant consideration in high-risk severe TR with multiple pacemaker leads; extends evidence to complex anatomy but remains hypothesis-generating pending randomized trials.**[[1]](https://www.sciencedirect.
Maia et al. (2026) studied this question. Transcatheter bicaval TricValve implantation improved symptoms from NYHA IV to I and prevented rehospitalizations at 8 months in a high-risk patient with severe tricuspid regurgitation and multiple pa.
