Current knowledge of functional tricuspid regurgitation (FTR) as a progressive entity, worsening the prognosis of patients irrespective of its aetiology, has led to renewed interest in the pathophysiology and assessment of FTR. For the proper management of FTR, not only its severity, but also the mechanisms, the mode of leaflet coaptation, the degree of tricuspid annulus enlargement and leaflet tenting, and the haemodynamic consequences for right atrial and right ventricular morphology and function have to be taken into account. A better assessment of the anatomy and function of tricuspid apparatus and tricuspid regurgitation severity should help with the appropriate selection of patients who will benefit from either surgical tricuspid valve repair/replacement or a percutaneous procedure, especially among patients who are to undergo or have undergone primary left-sided valvular surgery. In this article, we review the anatomy, pathophysiology and the use of imaging techniques to assess patients with FTR, as well as the various treatment options for FTR, including emerging transcatheter procedures. The limitations affecting the current approach to FTR patients and the unmet clinical needs for their management have also been discussed.
