Prosthetic valve with protective fabric covering around tissue anchor bases

A prosthetic valve for implantation within a native mitral valve, the prosthetic valve comprising:

• an annular valve body;
• a plurality of tissue anchors arranged about the valve body and configured to extend from connection points on the valve body;
• and
• at least one protective fabric covering extending over each of the connection points between each tissue anchor and the valve body,
• wherein:
• each connection point is covered by a separate protective fabric covering,
• each of the at least one protective fabric covering covers less than half of a surface area of the corresponding tissue anchor, and
• the at least one protective fabric covering is positioned in a radially outer direction relative to the annular valve body.
