A heart valve bioprosthesis (100) and a manufacturing method therefor. The heart valve bioprosthesis (100) comprises a valve stent (1), valve leaflets (2) and a valve auxiliary structure. The valve leaflets (2) are connected to the valve auxiliary structure. The valve auxiliary structure is connected to the valve stent (1). Both the valve leaflets (2) and the valve auxiliary structure are made of biomaterials. The valve stent (1) is integrally manufactured from an elastic material, and a sewing logo is preset on the valve auxiliary structure. The heart valve bioprosthesis enhances the biocompatibility with a human body, reduces the integral height of a valve, shortens sewing time and reduces the probability that thrombus or bacteria are attached to the heart valve bioprosthesis. Besides, the heart valve bioprosthesis is simple in manufacturing process and is good in compliance with heart tissue, thereby prolonging the service life of the valve. |
