Progress in Transcatheter Tricuspid Valve Repair and Replacement

Tricuspid regurgitation (TR) affects >1.5 million people in the United States (US) and is most often functional. The outcome of untreated TR is worse and isolated surgery for TR carries a poor prognosis. In recent times, transcatheter tricuspid valve replacement has gained momentum with an increasing number of devices and accumulating data. Sometimes, tricuspid valve anatomy is not suitable for transcatheter tricuspid valve repair due to large coaptation gaps or exceedingly tethered septal leaflets, and hence, replacement may be better for such situations. In this chapter, we describe the development of transcatheter tricuspid valve repair, replacement, outcomes, and future perspectives.
