A cardiac valve prosthesis, comprising: an expandable valve support provided with multiple fixing holes, an artificial valve provided on the valve support, and a thorn structure comprising an expandable thorn support and multiple thorns. The multiple thorns are provided on the thorn support, and are used for, when the cardiac valve prosthesis is implanted into a cardiac chamber, passing through the multiple fixing holes and penetrating tissue in the cardiac chamber so as to fix the valve support. The thorn structure and the valve support are provided independent of each other so that separate manufacturing and processing thereof can be achieved, and the thorn structure and the valve support work together in a non-connected manner so as to facilitate step-by-step load and release, such that the size of a delivery catheter and the length of the valve support can be effectively reduced, the risk of breakage is reduced, and it also facilitates recovery when the cardiac valve prosthesis is not released in place.
