What is Artificial heart valve?

22:00 - 4 May , 2021

Medical procedure



Also known as heart valve prosthesis, it is a mechanical or biological device that replaces the injured natural heart valve, and which is implanted through heart surgery. 

A damaged heart valve leads to stenosis or heart failure. The first causes the valve to narrow, preventing it from opening properly and hindering blood flow; while the second causes blood to travel in the wrong direction. 

The replacement of a valve with a prosthesis or artificial valve is indicated in patients whose symptoms are severe and significantly affect their quality of life, or in people in whom, despite not having important symptoms, their life is in danger due to their pathology. 

Prostheses classification:

  • Mechanical: they are made of various metals, plastics, or a combination thereof. They last between 15 and 25 years.
  • Biological: human or animal tissues are used in their making. They last between 10 and 12 years.

Potential risks of artificial heart valves:

  • Sudden blockages in the valve or in another body area due to blood clots.
  • By having to take anticoagulants permanently, the patient may experience serious bleeding. 
  • Infections that cause endocarditis that can damage or block the prosthesis.
  • Blockage or leak due to scar tissue. 
  • Hemolytic anemia due to damage to red blood cells.

Potential risks of replacement surgery:

  • Prosthesis functional problems. 
  • Bleeding and infection.
  • Blood clots.
  • Arrhythmia.
  • Stroke.
