Valvular & structural heart diseaseCohort study
Relevance of Residual Tricuspid Regurgitation for Right Ventricular Reverse Remodelling After Tricuspid Valve Intervention in Patients with Severe Tricuspid Regurgitation and Right-Sided Heart Failure
- Cohort study
- four sites
- two independent validation cohorts
Authors' conclusion
In patients with severe TR and right-sided heart failure undergoing TTVI, superior procedural results were associated with more pronounced RVRR.
Study context
- Population
- Patients with severe tricuspid regurgitation (TR) and right-sided HF treated with transcatheter tricuspid valve intervention (TTVI) (T-TEER, transcatheter annuloplasty, orthotopic or heterotopic TTVR)
- Participants
- 253 patients
- Exposure
- Residual TR ≤1+ vs 2+ vs ≥2+ after TTVI
- Outcome
- RVRR (3D echocardiography and cardiac magnetic resonance (CMR))
- Follow-up
- 30 days after the procedure
Main finding
As reported in the abstract
RVRR · 30 days
- Residual TR ≤1+: pronounced reduction of RV end-diastolic and end-systolic volumes
- Residual TR ≥2+: Right ventricular reverse remodelling (RVRR) effect gradually decreased with higher residual TR
- Findings validated in two independent cohorts
Observational data: associations, not effects.
Further findings
1-year survival
- Residual TR ≤1+ and 2+ associated with similar 1-year survival
RVRR by treatment modality
- RVRR only after T-TEER or orthotopic TTVR, not after heterotopic TTVR
Decongestion and functional improvement · 30 days
- Significant decongestion and functional improvement with all three treatment modalities
