Key result
Placement of a rigid or semi-rigid annular ring for functional tricuspid regurgitation has superior longevity compared with suture and flexible band repair techniques.
Why the study?
Does the placement of a rigid or semi-rigid annular ring improve repair longevity compared to suture and flexible band techniques in patients with functional tricuspid regurgitation?

Surgical repair of functional tricuspid regurgitation using rigid or semi-rigid annular rings provides superior longevity compared to suture or flexible band techniques.
Should not yet change tricuspid repair practice; leaves open need for randomized confirmation of ring durability.
Functional tricuspid regurgitation (TR) is a consequence of asymmetric dilation of the tricuspid annulus due to right ventricular dysfunction and enlargement from valvular and myocardial abnormalities of the left heart. Even if TR is negligible at the time of left-sided valvular surgery, it can worsen postoperatively and appear late, which implies a poor prognosis. Surgery for functional TR is underutilized, despite data demonstrating poorer outcomes in the face of residual TR. When performed, common repair techniques include placement of a rigid or semi-rigid annular ring, which have superior longevity compared with suture and flexible band repair techniques.

Weir et al. (2018) conducted a review in Functional tricuspid regurgitation. Rigid or semi-rigid annular ring placement vs. Suture and flexible band repair techniques was evaluated. Placement of a rigid or semi-rigid annular ring for functional tricuspid regurgitation has superior longevity compared with suture and flexible band repair techniques.
