A stent () used for a heart valve prosthesis and the heart valve prosthesis that includes the stent () and is used for heart valve replacement. The stent is configured to support a heart valve () and includes, along a longitudinal axis, an inflow section (), an outflow section () and a transition section () between the inflow section () and the outflow section (). The stent () has a contracted delivery configuration and an expanded deployed configuration. In the expanded deployed configuration, the inflow section () defines a concave contour that is complementary to a structure of a native valve annulus. The concave contour enables self-deployment and close adherence of the stent (), thereby preventing its displacement and perivalvular leakage after implantation.
