摘要：
A valve prosthesis includes an expandable frame. The expandable frame has an outflow portion and an inflow portion connected to the outflow portion. The frame defines a central lumen extending between the outflow portion and the inflow portion. The frame is generally cylindrical in a fully expanded configuration. When the frame is in the fully expanded configuration, an outer surface of the inflow portion is concave. The inflow portion has an upper inflow portion and a lower inflow portion. When the frame is in the fully expanded configuration, the upper inflow portion flares outwardly from the central lumen of the frame to greater extent than the lower inflow portion.
