Implication
Functional tricuspid regurgitation is characterized by a larger, more planar, and circular tricuspid valve annulus, which has mechanistic and therapeutic implications for tricuspid valve repair.
Key Points
- Characterize the three-dimensional geometric alterations of the tricuspid valve annulus associated with functional tricuspid regurgitation.
- Evaluated the geometry and spatial topography of the tricuspid valve annulus in normal configurations compared to states of functional tricuspid regurgitation.
- Normal tricuspid valve annuli demonstrated a bimodal configuration, featuring distinct anteroposterior high points and mediolateral low points.
- Development of functional tricuspid regurgitation resulted in annular enlargement alongside progressive loss of three-dimensional height, shifting toward a more planar and circular shape.
