- The study examines the proportionality of secondary tricuspid regurgitation (TR) and its impact on outcomes post tricuspid transcatheter edge-to-edge repair, using data from the TRIVALVE registry.
- Patients were divided into tertiles based on the ratio of effective regurgitant orifice area (EROA) to right ventricular end diastolic diameter (RVEDD): RV-dominant (low ratio), RV-TR codominant (intermediate), and TR-dominant (high ratio).
- Analysis revealed a trend toward worse prognosis, specifically higher all-cause mortality, in the RV-dominant group compared to the RV-TR codominant and TR-dominant groups over a median follow-up of 9.7 months.
- Findings suggest that the proportionality framework, previously applied in mitral regurgitation, is applicable to TR, helping identify higher-risk phenotypes for targeted therapeutic strategies.
