Eligibility Criteria
Inclusion Criteria
- •Aged 60 or older, regardless of gender;
- •Patients with moderate-severe or worse tricuspid regurgitation (TR≥3+);
- •The multidisciplinary cardiac team (composed of experts in cardiovascular internal medicine and surgery, imaging, anesthesiology, etc. \[No. of experts in cardiovascular surgery \>=2\]) considers the subjects to be at high risk for surgical operation (STS score \> 6.0%) and expects that they will benefit from the transcatheter tricuspid annulus repair;
