Tricuspid valve prosthetic annuloplasty

Tricuspid valve annuloplasty with a flexible prosthetic band

We thank the authors for this very interesting information [1]. It is known that with functional tricuspid regurgitation (TR) the annulus becomes larger, more planar, and circular. We support, ideally, annular remodeling with tricuspid annuloplasty to correct increased circularity and planarity, and restore the normal bimodal – elliptical shape of the tricuspid annulus to reduce leaflet tethering and stress [2]. This may be achieved by using prosthetic remodeling annuloplasty (i.e. flexible band and remodeling ring), especially in patients with significant TR and right-sided cardiac chambers dilatation, with history of right heart failure. We have a large experience in surgical treatment of significant TR due to left-sided valves disease. We suggest, that tricuspid valve prosthetic annuloplasty with remodeling flexible ring should be performed for correction of functional TR in patients with:

• significant TR (3+ or 4+) and/or significant tricuspid annulodilatation
  
• significant right ventricle enlargement and/or high pulmonary hypertension
  
• systolic dysfunction in one or both heart ventricles
  
• tricuspid leaflets tethering
  

In addition, we perform downsized ring annuloplasty. The systematic downsizing of the prosthetic ring has played an important role in decreasing the incidence of significant residual or recurrent TR, or both, after repair.
