Transcatheter tricuspid valve replacement

In patients who have undergone prior tricuspid valve replacement with a bioprosthetic valve (BPV) or tissue valve, eventual valve failure is inevitable. For high-risk operative patients, transcatheter tricuspid valve-in-valve (TVIV) replacement is now becoming a common intervention with either the Medtronic Melody™ transcatheter pulmonary valve or the Edwards SAPIEN™ Transcatheter Heart Valve (THV).[56][57][58][59]​​​​​ More trials are underway that will help to evaluate the effects of transcatheter TV therapies on clinical outcomes.[36]​ The framework of the previously placed BPV provides a landing zone for the transcatheter valve, which allows the interventional cardiologist to implant a new functional valve within the orifice of the old dysfunctional valve with a much lower risk than if a redo sternotomy and cardiopulmonary bypass were required.[60][61]
