What is heart valve replacement?

Replacement is necessary when the valve is degenerated beyond repair. The old valve is removed and replaced with a new valve mechanism, which can be:

  • bioprosthetic, made from animal tissue
  • mechanical, typically carbon covered with cloth
  • homograft, from donated human tissue
In some cases, replacement of a damaged aortic valve is accomplished by using the patient's own pulmonary valve (Ross Procedure).

Dr. Mehmet Oz, MD

As your heart beats, the tricuspid, pulmonic, mitral, and aortic valves open and close to control the flow of blood. Heart valve replacement is a surgical procedure to replace a natural valve that is not opening or closing all the way with an artificial one.
