Papillary muscle septalization combined with restrictive annuloplasty offers a novel approach to tricuspid valve repair, but preliminary results highlight the need for larger studies with long-term follow-up.
Functional tricuspid regurgitation (TR) often occurs in the setting of tricuspid valve (TV) annular enlargement and leaflet tethering that can either alter or appear as a consequence of changes in right ventricular geometry.1 Similar to the mitral valve, degree of leaflet coaptation and severity of TV regurgitation depends on the complex anatomic relationship between the valvular apparatus and the structure of the heart.1 Several studies have reported recurrent or residual rates of TV regurgitation between 10% and 20%, with TV tethering noted to be an independent predictor of repair failure.

Hirji et al. (2021) conducted an editorial in Functional tricuspid regurgitation (n=11). Papillary muscle septalization with restrictive annuloplasty was evaluated on 30-day mortality and recurrent tricuspid regurgitation.
