A new staging system for functional tricuspid valve pathology incorporating TR severity, annular dilation, and leaflet coaptation is proposed to improve clinical appraisal and decision-making.
Proposes a new staging system for functional tricuspid regurgitation that incorporates annular dilation and leaflet coaptation alongside TR severity to improve clinical decision-making.
The assessment of the etiology and severity of functional tricuspid regurgitation (FTR) has many limitations, especially when tricuspid regurgitation (TR) is more than severe. Instead of relying solely on TR severity, a new approach not only takes into account the severity of TR, but also pays strict attention to tricuspid annular dilation (size), the mode of tricuspid leaflet coaptation, and tricuspid leaflet tethering-factors often influenced by right ventricular enlargement and dysfunction. To simplify things, we propose a new staging system for functional tricuspid valve pathology using 3 parameters that may more accurately reflect the severity of the disease: TR severity, annular dilation, and mode of leaflet coaptation (extent of tethering). We believe that by utilizing these parameters, cardiologists and cardiac surgeons will be offered a better system for appraisal and decision-making in FTR.
Dreyfus et al. (Mon,) conducted a review in Functional tricuspid regurgitation. New staging system for functional tricuspid valve pathology was evaluated. A new staging system for functional tricuspid valve pathology incorporating TR severity, annular dilation, and leaflet coaptation is proposed to improve clinical appraisal and decision-making.
