Mitral valve of a pig for human use, United States, 1976-1979

Made:
1976-1979 in United States
maker:
Unknown

Artificial mitral valve made from mitral valve of pig, mounted for display, from USA, 1976-1979

The mitral valve is in the heart and in some cases may need to be replaced because of narrowing – which prevents blood flow – or as a result of disease. The practice of replacing damaged or diseased mitral valves with those from pig hearts began in the 1970s and continues today – the pig heart has a very similar structure to the human heart. The valve has to be chemically treated before it can be implanted. Despite this, it may still be rejected.

It is a controversial treatment as pigs have to die in order for us to harvest the valves.
