Study Details

Study Description

Brief Summary

The trial aims to evaluate the safety and effectiveness of LuX-Valve transcatheter tricuspid valve and delivery system which are intended to use in symptomatic patients with severe tricuspid regurgitation and high surgical risk.

Condition or Disease	Intervention/Treatment	Phase
Tricuspid Valve Insufficiency	Device: Tricuspid Valve Replacement System	N/A

Detailed Description

The TRAVEL study is a prospective multi-center single-arm trial for transcatheter tricuspid valve replacement with LuX-Valve. A series of physical, imaging and laboratory exams will be performed to determine whether a subject has severe tricuspid regurgitation with high surgical risk. Subjects who meet the criteria will then receive LuX-Valve implantation if an informed consent is obtained.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Tricuspid Valve Replacement System Subjects who received transcatheter tricuspid valve replacement with LuX-Valve and delivery system will be included in this arm.	Device: Tricuspid Valve Replacement System; To eliminate the tricuspid regurgitation through orthotopically replacing tricuspid valve with LuX-Valve system.

Outcome Measures

Primary Outcome Measures

1. Death [1 Year]

   All-cause Death

2. Tricuspid Regurgitation Reduction [1 Year]

   Tricuspid regurgitation measured with echocardiography in core lab reduces at least 2 grades.

Secondary Outcome Measures

1. Device or Procedure-Related Adverse Events [1 Year]

   Device related mortality, device malposition, right ventricular outflow tract obstruction, conduction system disturbances, new onset shunt across ventricular septum, coronary artery injury, valve failure, convert to open surgery, reintervention, embolization.

2. Device or Procedure-Related Adverse Events [2 Year]

   Device related mortality, device malposition, right ventricular outflow tract obstruction, conduction system disturbances, new onset shunt across ventricular septum, coronary artery injury, valve failure, convert to open surgery, reintervention, embolization.

3. Device or Procedure-Related Adverse Events [3 Year]

   Device related mortality, device malposition, right ventricular outflow tract obstruction, conduction system disturbances, new onset shunt across ventricular septum, coronary artery injury, valve failure, convert to open surgery, reintervention, embolization.

4. Device or Procedure-Related Adverse Events [4 Year]

   Device related mortality, device malposition, right ventricular outflow tract obstruction, conduction system disturbances, new onset shunt across ventricular septum, coronary artery injury, valve failure, convert to open surgery, reintervention, embolization.

5. Device or Procedure-Related Adverse Events [5 Year]

   Device related mortality, device malposition, right ventricular outflow tract obstruction, conduction system disturbances, new onset shunt across ventricular septum, coronary artery injury, valve failure, convert to open surgery, reintervention, embolization.

6. Major Adverse Event (MAE) [1 Year]

   MAE includes death, myocardial infarction, stroke, reoperation for bleeding, renal failure, pulmonary embolism, gastrointestinal hemorrhage, rehospitalization.

7. Major Adverse Event (MAE) [2 Year]

   MAE includes death, myocardial infarction, stroke, reoperation for bleeding, renal failure, pulmonary embolism, gastrointestinal hemorrhage, rehospitalization.

8. Major Adverse Event (MAE) [3 Year]

   MAE includes death, myocardial infarction, stroke, reoperation for bleeding, renal failure, pulmonary embolism, gastrointestinal hemorrhage, rehospitalization.

9. Major Adverse Event (MAE) [4 Year]

   MAE includes death, myocardial infarction, stroke, reoperation for bleeding, renal failure, pulmonary embolism, gastrointestinal hemorrhage, rehospitalization.

10. Major Adverse Event (MAE) [5 Year]

    MAE includes death, myocardial infarction, stroke, reoperation for bleeding, renal failure, pulmonary embolism, gastrointestinal hemorrhage, rehospitalization.

11. Functional Change in New York Heart Association (NYHA) Classification [1 Year]

    Subjects' heart function is ranged from NYHA I to IV based on how much a patient is limited during physical activity. NYHA I means no limited on physical activity while NYHA IV means unable to take any physical activity.

12. Change in Quality of Life (QOL) is evaluated with Kansas City Cardiomyopathy (KCCQ) [1 Year]

    KCCQ score ranges from 0 to 100, which 0 reflects the worst health status and 100 reflects the best health status.

13. Change in Quality of Life (QOL) is evaluated with Six Minute Walk Test (6MWT) [1 Year]

    6MWT distance is recorded and compared with baseline during follow-up.
