Due to the increased life expectancy and continual improvements in cardiological treatment options, diseases of the tricuspid valve, in particular tricuspid valve insufficiency will become increasingly more recognized as an interventional target. While tricuspid stenosis is rare and can be effectively treated with balloon valvuloplasty, no effective transcatheter approach to tricuspid regurgitation (TR) has yet been established. As the tricuspid annulus is a complex and highly dynamic structure that offers little resistance, orthotopic long-term fixation of transcatheter valves with the current techniques is challenging and has not yet been performed in human patients. Alternative treatment concepts include transcatheter caval valve implantation (CAVI) to address the regurgitation of blood into the caval veins, which has resulted in hemodynamic improvement and is currently undergoing further clinical investigation. Other interventional treatment concepts are aimed at tricuspid valve repair, e.g. by annular plication with the Mitralign™ device or the TriCinch™ system. In the medium-term it can be assumed that percutaneous systems and therapy options will become available for these indications whereby the functional and prognostic effects of these treatment procedures will be corroborated in the appropriate patient groups by corresponding studies.
