Valvular & structural heart diseaseCohort study
Cardiac Remodeling Following Transcatheter Tricuspid Valve Annuloplasty for Tricuspid Regurgitation
- Retrospective cohort study
- multicentre
- 2 German high-volume centres
Authors' conclusion
TTVA is associated with a significant and sustained reduction of TR for more than 1 year. Additionally, patients demonstrated distinct positive cardiac remodeling and functional improvement.
Study context
- Population
- Consecutive patients undergoing transcatheter tricuspid valve annuloplasty (TTVA) (Cardioband) for severe tricuspid regurgitation (TR), 2019–2023
- Participants
- 156 patients
- Exposure
- Follow-up vs baseline after TTVA
- Outcome
- Long-term efficacy and right heart remodeling (right atrial and RV parameters, NYHA class)
- Follow-up
- Median 435 days
Main finding
As reported in the abstract
| Group | Right atrial area | Right ventricular (RV) length | RV midventricular dimension | RV basal dimension |
|---|---|---|---|---|
| Baseline | 36.0 ± 10.1 cm² | 67.5 ± 9.4 mm | 42.6 ± 8.6 mm | 47.8 ± 6.8 mm |
| Follow-up | 30.4 ± 10.7 cm² | 63.7 ± 9.1 mm | 35.6 ± 7.8 mm | 42.6 ± 7.5 mm |
- TR reduction to ≤2+
- 71%
- NYHA class improved to ≤II
- 68%
- TR and NYHA improvement
- P < 0.001
- All right heart dimensions significantly reduced at follow-up
- P < 0.001
Observational data: associations, not effects.

RV basal diameter, torrential to severe TR reduction (subgroup)
