Prognostic Implications of Residual Tricuspid Regurgitation Grading After Transcatheter Tricuspid Valve Repair
- Registry cohort study
Authors' conclusion
The moderate residual TR group was heterogeneous and encompassed patients with markedly different clinical outcomes. Refining TR grade classification with a more granular 4-grade scheme improved outcome prediction.
Study context
- Population
- Patients with severe isolated functional tricuspid regurgitation (TR) who underwent transcatheter tricuspid valve (TTV) repair in TRIGISTRY
- Exposure
- Residual TR grades after TTV repair
- Moderaten = 319
- Mild to moderaten = 201
- Moderate to severen = 118
- Outcome
- Survival by residual TR severity at discharge
- Follow-up
- 2 years
Main finding
As reported in the abstract
2-year adjusted survival by residual TR grade at discharge
None/mild vs None/mild: P = 0.0001 · None/mild vs None/mild: P = 0.001 · Moderate to severe vs Mild to moderate: P = 0.006 · None/mild vs Mild to moderate: P = 0.67 · Moderate to severe vs Severe: P = 0.96
