Transcatheter tricuspid valve replacement
Despite the explosion in the field of transcatheter aortic valve implantations over the last 10 years, only a handful of transcatheter tricuspid valve-in-valve implants have been described to date. This review describes the basic anatomy and pathology of the tricuspid valve. Current treatment remains surgical repair or replacement and the shortcomings is discussed. Results of surgical replacement are varied but generally not very good. Redo surgery has even more problems and this is the field where transcatheter valve-in-valve implants may have its biggest role. Technical aspects of the procedure is discussed, including the choice of valve, the approach and positioning of the device. © TOUCH BRIEFINGS 2012.
