EuroPCR 2025 | TRI-SCORE for Predicting Mortality After Tricuspid Valve TEER: The EURO TR Registry

Researchers analyzed a total of 1062 patients who underwent transcatheter edge-to-edge repair (TEER) for tricuspid regurgitation (TR).

Risk was classified using the TRI-SCORE: low (0–3 points), intermediate (4–5 points), and high (≥6 points).

Mortality was assessed at 30 days and two years.

The average age was 80 years, 48% of subjects were women, 63% had undergone prior hospitalization, the average TRI-SCORE was 6, the ejection fraction was 55%, and 27% had an RV pacemaker lead.

The cause of TR was secondary in 76.3% of cases, primary in 14.4%, and mixed in the remainder.

Thirty-day and two-year mortality rates were as follows:

• Low risk population: 0% and 4.6%
• Intermediate risk population: 1.9% y 13.9%
• High risk population: 2.9% y 27.8%
