摘要： The present disclosure relates to a tricuspid valve frame and a valve prosthesis thereof. The tricuspid valve frame includes an inner frame part and an outer frame part. An end of the inner frame part is formed into an inflow end. An end of the outer frame part is formed into an outflow end. Another end of the inner frame part away from the inflow end is fixedly connected to another end of the outer frame part away from the outflow end. In an expanding state, the inflow end has a smaller radial size than the outflow end. The inflow end in the expanding state forms a support edge everting towards a side away from an axis of the tricuspid valve frame. In the present disclosure, the support edge is designed, so that the valve frame can be reliably supported on a valve annulus. Meanwhile, by using a structural form that the outer frame part and the inner frame part are processed separately, the molding of connecting claws are facilitated. In addition, the radial size of the inflow end is smaller than the radial size of the outflow end, it can be ensured that a force transmitted to the valve annulus does not have adverse effects on the valve annulus, and the valve prosthesis can also be prevented from falling off at the same time.
