Robots take on tricuspid valve repair in tiny early trial
NCT ID NCT07516145
First seen Jun 25, 2026 · Last updated Sep 18, 2026 · Updated 2 times
Summary
This early study tests a robotic catheter system to replace the tricuspid valve in 10 patients with severe leakage (regurgitation) who are too high-risk for open surgery. The robot aims to improve precision and safety while reducing radiation exposure for doctors. The main goal is to see if the procedure can be done successfully without major complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lux-Valve Plus system (transcatheter tricuspid valve replacement device) delivered via a robotic catheter
- What this could lead to
- If successful, this could make tricuspid valve replacement safer and more precise, reducing recovery time and radiation exposure for patients.
- What could go wrong
- This is a very early, small trial with only 10 participants. The robotic system is new and unproven; risks include procedural failure, bleeding, stroke, or device complications.

Inclusion Criteria: * Age 18-90 * Severe symptomatic TR * Deem high risk for tricuspid valve surgery determined by a multidisciplinary heart team (including cardiologists, cardiac surgeons and cardiac anesthetists) and * Anatomically feasible for transjugular transcatheter tricuspid valve replacement using the Lux-valve plus system * Able to consent Exclusion Criteria: * Prior TV repair or replacement that would interfere with Lux-valve plus implantation * severe pulmonary hypertension (pulmonary artery systolic pressure \>70 mm Hg or \>2/3 systemic with pulmonary vascular resistance \>5 WU after vasodilator challenge) * Pregnant or nursing patients and those who plan pregnancy during the study period. Female patients of childbearing potential must have a negative pregnancy * Left Ventricular Ejection Fraction (LVEF) \<40% or; * Evidence of intracardiac mass, thrombus or vegetation or; * Anatomical structures precluding proper device deployment or device vascular access, evaluated by echo or CT or; * Surgical correction is indicated for other concomitant valvular disease (e.g., severe aortic, mitral and/or pulmonic valve stenosis and/or regurgitation); Subjects with concomitant valvular disease may treat their respective valve first and wait 2 months before being reassessed for the trial. * Sepsis or active endocarditis within 3 months, or infections requiring antibiotic therapy within 2 weeks prior to the planned procedure or; * Active peptic ulcer or active gastrointestinal (GI) bleeding precluding anticoagulation or antiplatelet therapy or; * Underwent any cardiac or non-cardiac interventional or surgical procedure within 30 days prior to the procedure or planned to have the interventional or surgical procedure within 60 days after implant procedure (e.g., cardioversion, ablation, percutaneous coronary intervention, etc); * Recent (within 90 days prior to procedure) stroke, transient ischemic attack, or myocardial infarction; * Life expectancy is less than 1 year; * Current participation in another investigational drug or device study.
