Key result
IVC-to-tricuspid annulus distance varies widely in symptomatic TR, averaging ~18 mm.
Why the study?
The anatomic relationship between the inferior vena cava and tricuspid annulus and its impact on transcatheter tricuspid valve interventions is not well characterized.
Observational (n=50)
CT analysis reveals significant variability in the IVC-to-TA relationship among patients with symptomatic TR, highlighting the importance of pre-procedural imaging for planning transcatheter tricuspid valve interventions.
No takes yet. Share an insight, caveat, or question.
Variability may support individualized pre-procedural CT planning for transcatheter TR interventions; leaves open effects on outcomes.
Ranard et al. (2022) conducted an observational in Symptomatic tricuspid regurgitation (n=50). Anatomic relationship between the inferior vena cava (IVC) and tricuspid annulus (TA) was evaluated on IVC-TA relationship. The anatomic relationship between the inferior vena cava and tricuspid annulus exhibited significant variability (mean 18.2 ± 7.9 mm) in patients with symptomatic tricuspid regurgitation.
