Comprehensive Dynamic 3-Dimensional Analysis of the Tricuspid Valve in Functional Tricuspid Regurgitation: Implications for Prophylactic Tricuspid Valve Intervention
Authors' conclusion
3D echocardiographic assessment of TA helps better understand its geometry and dynamism in functional TR and is more accurate than 2D measurements for RV function assessment.
Study context
- Population
- Patients undergoing left-sided heart surgery, 2 US academic centres, November 2018–April 2020108 patients collected
- Participants
- 92 patients
- Exposure
- Significant functional tricuspid regurgitation (TR) vs no significant functional TR
- NTRn = 74reference
- Functional TR (FTR)n = 18
- Outcome
- 3D motion of TA (lateral, anterolateral, posterolateral coordinates)
Methodological detailsintraoperative 3D echocardiography, postprocessing software analysis, computational modeling, 2 academic centres

Main finding
As reported in the abstract
- Lower 3D tricuspid annulus (TA) motion in FTR vs NTR; larger TA size during the cardiac cycle, with less excursion and reduced annular dynamism in FTR
- FTR vs NTR: P = 0.02
- FTR vs NTR: P = 0.009
- FTR vs NTR: P = 0.002
Observational data: associations, not effects.

TA diameters in FTR
- Anteroseptal-posterolateral diameter consistently larger than conventional septolateral diameter in all cardiac cycle phases
