Authors' conclusion

Assessment of the RV capacity to adjust for changes in loading conditions predicted mortality in patients with severe symptomatic TR undergoing T-TEER.

Study context

Population
Patients with relevant tricuspid regurgitation (TR) undergoing tricuspid transcatheter edge-to-edge repair (T-TEER), EuroTR registry 2019–2022, ≥2 years follow-up
Participants
364 patients
Exposure
Right ventricular (RV) function parameters and Dandel's index as predictors of mortality
Outcome
All-cause mortality
Follow-up
2 years

Main finding

As reported in the abstract

univariable
Hazard ratio (95% CI)
Dandel's index
0.67(0.53–0.85)
TAPSE
0.72(0.62–0.84)
FAC
0.73(0.59–0.91)
TAPSE/sPAP
0.8(0.65–0.99)
Died at 2-year follow-up
36%
Dandel's index maintained predictive value in multivariate model, with TAPSE and absence of signs of right HF
P < 0.001
Optimal Dandel's index threshold (ROC)
20.5

Observational data: associations, not effects.

Further findings

Cardiac hospital readmission

Dandel's index threshold of 20.5 also predicted cardiac hospital readmission
