   The papillary muscles attach the mitral valve (the valve between the left atrium and the left ventricle) and the tricuspid valve (the valve between the right atrium and the right ventricle) to the wall of the heart. If the papillary muscles are not functioning properly, the mitral valve may leak during contraction of the left ventricle.

   Mechanical failure could result from a valve not working properly, allowing blood to flow backwards and pool in the heart, rather than be propelled forward from chamber to chamber and into the vessels as it should.

[14] Bovine (cow) tissue is most commonly used, but some are made from porcine (pig) tissue. [15] The tissue is treated to prevent rejection and calcification (where calcium builds up on the replacement valve and stops it working ...
