Tricuspid Regurgitation
Conditions
Brief summary
This is a prospective, single-arm, multi-center trial to evaluate the LuX-Valve Plus system for treating symptomatic at least severe TR in patients who are deemed high risk for tricuspid surgery. Treatment with the LuX-Valve Plus system may enable patients with tricuspid regurgitation to have a complete tricuspid valve replacement with a minimally invasive approach. Up to 150 subjects will be implanted at up to 24 institutions worldwide. No single institution will be allowed to register more than 25% of total subjects. There is no minimum number of subjects to be registered at any site. Up to3 per site, may be implanted by operators without prior experience using the LuX-Valve Plus device to gain hands-on experience.Each site has a maximum of 3 roll-in cases. The data of roll-in subjects will not count towards the overall enrollment cap. Safety and performance results of roll-in subjects will be analyzed in subgroups. All subjects will be evaluated at baseline, procedure, discharge, 30 days, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years post-procedure.
Interventions
Due to unsustainable effect of medical therapy and high risks of surgical treatment, transcatheter tricuspid valve intervention (TTVI) has been a major field of study in the world in the last 10 years. TTVI could potentially reduce TR with lower periprocedural risk and improve the patient's clinical status and prognosis. Per the ESC guidelines for surgical and interventional treatment of tricuspid regurgitation (2021 ESC/EACTS Guidelines for the Management of Valvular Heart Disease), Transcatheter intervention for symptomatic secondary severe TR may be considered in inoperable patients at a Heart Valve Centre with expertise in the treatment of tricuspid valve disease (Class IIb). Transcatheter tricuspid treatment options can be divided into categories based on their mechanism of action: coaptation enhancement (edge-to-edge repair and spacer device), annuloplasty devices, caval valve implantation and valve replacement.
