Predicted mortality percentages are the original model's score-specific estimates. They are not individualized guarantees and may not be calibrated to every contemporary centre or population.
About the TRI-SCORE
The TRI-SCORE is a disease-specific clinical risk score developed to predict in-hospital mortality after isolated tricuspid valve surgery in adults with severe, non-congenital tricuspid regurgitation. The original derivation cohort included 466 patients from 12 French centres (2007–2017); in-hospital mortality was 10%.
The simplified score contains eight preoperative variables and ranges from 0 to 12 points. Variables with an odds ratio between 1 and 2 receive 1 point; variables with an odds ratio of 2 or greater receive 2 points.
Variables and scoring
| Variable | Definition | Points |
|---|---|---|
| Age | ≥70 years | 1 |
| NYHA class | III–IV | 1 |
| Right-sided HF signs | Severe JVD, ascites and/or marked peripheral oedema | 2 |
| Furosemide | Daily dose ≥125 mg | 2 |
| Renal function | GFR/CrCl <30 mL/min (Cockcroft–Gault) | 2 |
| Total bilirubin | Above local laboratory reference threshold | 2 |
| LVEF | <60% | 1 |
| RV dysfunction | Moderate/severe | 1 |
Original predicted in-hospital mortality

| 2 | 3% | 1% |
| 3 | 5% | 0% |
| 4 | 8% | 10% |
| 5 | 14% | 18% |
| 6 | 22% | 25% |
| 7 | 34% | 32% |

Important application notes
- Use preoperative values and clinical findings relevant to the planned operation.
- The original development population was adults undergoing isolated surgery for severe non-congenital TR; do not assume the same calibration for congenital disease, concomitant procedures, transcatheter interventions, or non-operative populations.
- Right-sided HF signs and RV dysfunction require clinical and echocardiographic assessment; the calculator cannot replace clinician judgement.
- For bilirubin, the original online score specifies elevation above the laboratory threshold rather than a universal numeric cut-off.
- The Cockcroft–Gault calculation uses actual body weight in the conventional equation; clinical appropriateness of weight selection in extremes of body habitus requires judgement.
