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|
