Abstract

A replacement heart valve can have an expandable frame configured to engage a native valve annulus. A valve body can be mounted onto the expandable frame to provide functionality similar to a natural valve. The valve body has an upstream end and a downstream end, and a diameter at the downstream end is greater than a diameter at the upstream end.
