What is a porcine heart valve?

Porcine aortic valve. In porcine BHV, the valve tissue is sewn onto a fabric covered metal wire stent, made from a cobalt-nickel or another alloy. A Dacron fabric covers the entire stent and a sewing skirt is fashioned and attached to the base of the wire stent.

Which type of valve is porcine heart valve?

Stented valves are made from porcine aortic valves (e.g., Mosaic) or from bovine pericardial tissue (e.g., Carpentier-Edwards Perimount; see Fig. 10-1 D).

What type of valve is porcine?

Tissue Heart Valves. Tissue heart valves (sometimes called “bioprosthetic” valves) are harvested from pig heart valves (porcine) or from the sac surrounding the heart of a cow (bovine). These tissues are treated and neutralized so that the body will not reject them.

How long does a porcine heart valve last?

Tissue valves, which are made from pig heart valves or cow heart-sac tissue, typically last about 15 years. But they usually don’t require the lifelong use of anti-clotting drugs. Older people are more vulnerable to the bleeding side effects of warfarin.

How are porcine valves used in heart surgery?

Recently, I toured Edwards manufacturing center and learned how porcine valves are manufactured. So you know, a porcine valve replacement is actually taken from the heart of a pig. I know that sounds a little odd…. But, porcine valves have been used in heart valve replacement surgery for over 20 years.

Are there any downsides to having a porcine heart?

Obviously, this is one of the downsides of porcine valves as porcine valve leaflets tend to calcify and degenerate. This can lead to a collapsed pig valve in the human heart. However, some recent studies are beginning to challenge that adverse effect of pig valves.

Can a pig be used for heart valve replacement?

But, porcine valves have been used in heart valve replacement surgery for over 20 years. That makes pig valves a very safe and very credible alternative for patients requiring valve replacement.

What’s the difference between bovine and porcine valve prostheses?

Survival after Aortic Valve Replacement with Bovine or Porcine Valve Prostheses: A Systematic Review and Meta-Analysis This systematic review and meta-analysis suggest no difference in survival between patients who received a bovine versus a porcine bioprosthesis after aortic valve replacement.
