1. A heart valve prosthesis anchored to an interventricular septum, comprising a valve supporting frame and a fixing device; the valve supporting frame comprises a valve stitching section and an artificial valve; the artificial valve is fixedly connected to the valve stitching section; the fixing device comprises only one fixing and supporting section and a fixing member, and the fixing and supporting section and the fixing member are two different components; one end of the fixing and supporting section is connected to a proximal portion of the valve stitching section; and another end of the fixing and supporting section is connected only to the interventricular septum of a patient by the fixing member, to support the heart valve prosthesis and limit axial movement of the heart valve prosthesis;
wherein the heart valve prosthesis further comprises a ring; the ring is connected to a main body of the valve stitching section, at a distal end of the valve stitching section, an end face of the ring is not higher than the valve stitching section; and in a free state, part of the ring is placed in the patient's atrium;
wherein in a cross-section perpendicular to a central axis of the artificial valve, a center of the valve stitching section and a center of the ring are not coincident.
