Risk x clots


Artificial valves statistically are more prone to cause clots. Red blood cells crash against their hard surfaces triggering the cascade for clotting. This does not occur with bio prosthetic valves made of animals like pigs, or cadaver duramadre( meningeal layer).

Quite safe


In this day in age, several hundred thousand of these procedures have been performed successfully. Three types of valves: animal (porcine or bovine), bioprosthetic, mechanical. The latter requires long term blood thinners and blood test have to be performed periodically to ensure the blood is thinned enough. The latter tends to have a longer life, too.

Depends on the type.


There are several "artificial" heart valves, each with different manufacturers. Here in the US - Surgical mechanical valves - mostly St. Jude Surgical biologic valves - mostly Edwards Lifesciences Percutaneous (stented) valve - Edwards currently available in US, but other companies like Medtronic and St. Jude (and other small companies) have devices in trials or experimental phase.
