摘要：
A prosthetic heart valve having an inflow end and an outflow end includes a stent having a collapsed condition, an expanded condition, and a plurality of cells arranged in circumferential rows. The stent may include one or more securement features. One securement feature may be an anchor arm having a body portion and a free end extending from the body portion, the body portion being coupled to a perimeter of one of the plurality of cells, with the free end extending toward the inflow end in an expanded condition of the anchor arm. Another securement feature may include a flange formed of a braided mesh and having a body portion coupled to the stent and a flared portion adjacent the inflow end of the prosthetic heart valve. A valve assembly is disposed within the stent and has a plurality of leaflets.
