Several surgical options for the correction of damaged cardiac valves exist. Valvular replacement will be usually performed if the functional impairment of the Aortic or Mitral valve is severe.
There are two kinds of valvular prostheses:
1.Mechanical valves – made of materials such as plastic, carbon or metal. They are durable and resistant for extensive periods. Because blood tends to stick to these materials and create blood clots around them, people who underwent implantation of such valves must take anticoagulants for lifetime.
2.Biological valves – made of animal or human tissues. They are less resistant than mechanical valves, but do not require use of anticoagulants.
Usually, they must be replaced approximately every 10 years.
