Transcatheter tricuspid valve implantation with the Cardiovalve system.

Historically considered the 'forgotten valve', there has been increasing attention on the percutaneous transcatheter treatment of tricuspid regurgitation (TR). Prevalence of TR is high in the elderly population and prior studies have shown worse outcomes in patients with severe TR. Advances in transcatheter-based therapies have shed a new light in the treatment of TR and one such treatment option is tricuspid valve replacement with the Cardiovalve system. This device is approved as an early feasibility study in the US and also approved for clinical study in Germany, Italy and Switzerland. The Cardiovalve device is in the early stage of clinical studies and this article reviews the existing clinical data and future studies on percutaneous transcatheter treatment of severe TR.
