Changes in Right Ventricular Function and Clinical Outcomes Following Tricuspid Transcatheter Edge-to-Edge Repair

Eur J Heart FailPublished

  • Retrospective cohort study

Authors' conclusion

Post-procedural increase in RVFAC after T-TEER is associated with improved outcomes in patients with RV dysfunction.

Study context

Population
Patients undergoing tricuspid transcatheter edge-to-edge repair (T-TEER) with echocardiographic follow-up at 3 months45 with baseline RV fractional area change (RVFAC) <35%
Participants
204 patients
Exposure
Right ventricular (RV) responders vs RV non-responders after T-TEER, by baseline RVFAC
  • RV respondersn = 71
Outcome
Composite of:
  • Mortality
  • HF hospitalization
Follow-up
Within 1 year

Main finding

As reported in the abstract

  • Baseline RVFAC <35%: RV responders had a lower risk of the composite outcome than RV non-responders
  • Baseline RVFAC ≥35%: association not significant
  • Significant interaction between RV responder and baseline RVFAC

Observational data: associations, not effects.

Further findings

Predictors of RV response (baseline RVFAC <35%)

Smaller RV diameter and greater reduction of tricuspid regurgitation predicted RV response
