Impact of Proportionality of Secondary Tricuspid Regurgitation on Outcomes After Tricuspid Transcatheter Edge-to-Edge Repair

Key Points

The research aims to evaluate how the proportionality of secondary tricuspid regurgitation impacts patient outcomes following transcatheter edge-to-edge repair.
Analyzed the relationship between effective regurgitant orifice area (EROA) and right ventricular end-diastolic diameter (RVEDD)

Structured PICO

Does the proportionality of secondary tricuspid regurgitation impact survival after tricuspid transcatheter edge-to-edge repair?

Population

Patients with secondary tricuspid regurgitation undergoing tricuspid transcatheter edge-to-edge repair

Intervention

Assessment of proportionality of tricuspid regurgitation using EROA/RVEDD

Outcome

Survivalhard clinical

Applying the framework of proportionality to secondary tricuspid regurgitation identifies an RV-dominant phenotype associated with worse survival after transcatheter edge-to-edge repair.

Abstract

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.
