Valve Types

Aortic valves can be replaced with either a mechanical (metal) or biologic (tissue) prosthetic valve.

Discuss with your provider the advantages and disadvantages of each valve.

  Mechanical or Metal Valve Biologic or Tissue Valve
Durability metal |Lifetime expectancy

tissue |Average expectancy is 10–20 years

Note: Long-term durability of TAVR valves is less certain than surgical tissue valves since they have only been in use for approximately 10 years.

Primary risk metal |Blood clot  tissue |Additional surgery to replace valve
Additional medications metal |Lifetime requirement for blood thinners to prevent blood clots tissue |Long-term use of aspirin recommended
Insertion approach metal |Surgical tissue |Surgical or transcatheter
