Results: The durability of recent xenografts has been reported to be over 90% at 10years after aortic or mitral valve replacement for elderly patients more than 65years of age, and therefore the guidelines now recommend the use of bioprostheses for patients over 65years of age. Bioprostheses are also recommended for valve replacement of the right side of the heart by several authors; however, no clear guidelines are available. Trans-catheter aortic valve replacement and percutaneous pulmonary valve implantation are promising procedures for high-risk patients, although evaluation of the long-term durability of these valves is mandatory. Conclusions: This article will review the development of the tissue valve for valve surgery.
