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.
The normal TVA has a bimodal shape with distinct high points located anteroposteriorly and low points located mediolaterally. With functional TR, the annulus becomes larger, more planar, and circular. These changes in annular shape with TR have potentially important mechanistic and therapeutic implications for tricuspid valve repair.
