Authors' conclusion
In this large cohort of invasively characterized patients undergoing TTVI, congestion patterns involving right-sided congestion were associated with low procedural success and higher mortality rates after TTVI.
Study context
- Population
- Patients with severe tricuspid regurgitation (TR) undergoing right heart catheterization before transcatheter tricuspid valve intervention (TTVI)
- Participants
- 813 patients
- Exposure
- Congestion patterns by invasive right atrial pressure (RAP) and pulmonary capillary wedge pressure (PCWP) before TTVI
- Outcome
- Mortality
- Follow-up
- 2 years
Main finding
As reported in the abstract
2-year mortality
- Mean RAP and PCWP associated with 2-year mortality (Youden cut-offs 17 mmHg and 19 mmHg)
- P < 0.01 for all
Observational data: associations, not effects.
