Heterotopic Implantation Of the Edwards-Sapien Transcatheter Aortic Valve in the Inferior VEna Cava for the Treatment of Severe Tricuspid Regurgitation (HOVER)

This is a prospective multi-center, non-blinded (open label), non-randomized safety and feasibility study of the heterotopic implantation of the Edwards-Sapien XT or S3 valve in the inferior vena cava for the treatment of severe tricuspid regurgitation in patients who are inoperable or at a very high surgical risk for tricuspid valve replacement.
