Tissue valves only last 10-15 years. In spite of chemical treatments to improve durability, tissue valves typically last about 10 to 15 years. They usually fail because of the same calcification process that affected the original valve. Tissue valves can also tear and become infected.
Tissue valves are most appropriate for people who are less likely to outlive their valves, which includes people who:
Are older than 65.
Are younger than 60 and have lung disease.
Have heart failure
Have coronary artery
Have a life expectancy of less than 10 years.
