Transcatheter Tricuspid Valve Replacement

Tricuspid regurgitation (TR) is a common entity, most commonly functional in nature due to right-sided dysfunction in the setting of concomitant cardiac disease or pulmonary hypertension. Patients living with TR often experience numerous limitations as a result of right-sided heart failure symptoms, including functional decline, frequent hospitalizations, liver failure, and kidney failure. Furthermore, patients with significant TR demonstrate worse survival, although a cause-and-effect relationship has not been proven. For patients with a degenerated surgical bioprosthesis or valve ring, placement of a transcatheter aortic valve prosthesis in a valve-in-valve or valve-in-ring fashion may provide symptomatic benefit. For patients with native valve regurgitation, novel devices for treatment are currently under development.
