Transcatheter Tricuspid Valve Intervention Risk Scores: Assessment in an International Multicenter Cohort
Authors' conclusion
The currently available TTVI risk scores derived from surgical or early TTVI cohorts may not be well suited for accurate risk assessment in contemporary TTVI. The surgical scores when applied to TTVI are miscalibrated, and the TRIVALVE score lacks discrimination.
Study context
- Population
- Patients undergoing transcatheter tricuspid valve intervention (TTVI) (tricuspid TEER, transcatheter tricuspid valve replacement or annuloplasty), 2019–2024
- Participants
- 457 patients6 international centres
- Exposure
- TTVI risk scores (TRI-SCORE) vs STS-TR vs TRIVALVE risk scores
- Outcome
- Discrimination (C statistic) and calibration of each score for its endpoint
