Abstract
A heart valve prosthesis anchored to an interventricular septum. The heart valve prosthesis includes a valve supporting frame and a fixing device. The valve supporting frame includes a valve stitching section and an artificial valve. The artificial valve is fixedly connected to the valve stitching section. The fixing device includes a fixing and supporting section and a fixing member. One end of the fixing and supporting section is connected to a proximal end of the valve stitching section, and another end of the fixing and supporting section is connected to the interventricular septum of a patient by the fixing member, to support the heart valve prosthesis and prevent the heart valve prosthesis from axially moving.
