Abstract:
Recurrent tricuspid regurgitation after failed ring annuloplasty is associated with high mortality rates and unfavourable clinical outcomes. Transcatheter tricuspid valve-in-ring (TVIR) replacement offers an alternative to high-risk surgical reoperation, but challenges remain. We present a case of a 67-year-old male who underwent tricuspid annuloplasty 3 years ago and developed severe recurrent tricuspid regurgitation (regurgitation volume = 36 mL) 6 months ago. To avoid a high-risk thoracotomy, we finally performed TVIR replacement using the novel device, LuX-Valve Plus system, via the transjugular approach. Cardiovascular three-dimensional printing technology was utilized to investigate the distinct advantages offered by the new device in this specific intervention, as well as to simulate the procedure. Successful TVIR replacement resulted in significant symptomatic improvement. TVIR replacement with the LuX-Valve Plus system is feasible for failed annuloplasty ring cases. Patient-specific three-dimensional printed models enable personalized procedural planning, enhancing safety and precision.
