Authors' conclusion

The conceptual framework of proportionality is applicable to TR with EROA/RVEDD, defining a higher risk RV-dominant phenotype with a trend towards worse survival after tricuspid transcatheter edge-to-edge repair.

Study context

Population
Patients undergoing tricuspid transcatheter edge-to-edge repair from the TRIVALVE registrypatients included · right ventricular (RV) dominant 67 · RV-TR codominant 68 · tricuspid regurgitation (TR) dominant 69
Participants
204 patients
Exposure
Tertiles of the ratio between effective regurgitant orifice area (EROA) and RVEDD
  • RV dominantn = 67
  • RV-TR codominantn = 68
  • TR dominantn = 69
Outcome
All-cause mortality
Follow-up
Median 9.7 months (4.2-12.0)

Main finding

As reported in the abstract

  • Trend towards worse prognosis for the RV-dominant group, as compared with the RV-TR codominant and TR dominant groups

Observational data: associations, not effects.

Further findings

Baseline characteristics

The 3 groups presented different baseline characteristics
