Abstract: A heart valve prosthesis, the heart valve prosthesis comprising a large stent (10) and a valve stent (20) that are manufactured separately, the large stent (10) being connected to the valve stent (20). Since the stent and the valve are separated, the stent has stronger radial stiffness so as to provide a greater radial supporting force, and even if the valve stenosis of a patient is very serious, the stent may still be opened to ensure the success rate of an operation; in addition, the thickness of the valve is not affected by the thickness of the stent, and thus the design range of the thickness of the valve is increased. During loading, a raw material having a small thickness does not need to be selected for the valve due to the stiffness of the structure of the stent being strong and the space occupied thereby being large. Meanwhile, usage is not affected due to the valve being easily crushed by the structure of the stent having strong stiffness.
