Bioprosthetic Heart Valves: Upgrading a 50-Year Old Technology
Frontiers in Cardiovascular Medicine, 2019 Prosthetic heart valves have been commonly used to address the increasing prevalence of valvular heart disease. The ideal prosthetic heart valve substitute should closely mimic the characteristics of a normal native heart valve.

International Journal of Clinical Practice, 2014 Heart valve replacements improve symptoms and life expectancy but may have potential problems. Biological replacements have limited durability but do not require anticoagulation and are usually used for the relatively elderly. Mechanical valves have a virtually zero primary failure rate but require anticoagulation and are usually used for the ...
