Is There A Major Difference Between Cow And Pig Heart Valves For Replacement
Not really: Both offer the advantage of not requiring "blood thinning" on a long term basis. Unlike a "mechanical" valve, cow and pig don't last longer than 7-12 years(with a few exceptions). Otherwise, the outcomes in both valves are generally the same and for all intents and purposes, either one is a reasonable choice in a patient who does not desire blood thinning. ...Read moreGet help from a doctor now ›
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve.

Why is it that the human body does not reject bovine or pig heart valves. Can cells from different animals survive in humans?
Medical technology: The valves are derived from pig or bovine but are treated in a laboratory to remove the antigens that would cause a reaction against them in a human body. Medical technology is amazing! ...Read moreGet help from a doctor now ›
Mitral valve: Outcomes with mitral valve replacement are not quite as good as aortic valve replacement but, in many cases, the mitral valve can be repaired which is always preferable to replacement and has excellent outcomes if it's an option. The tricuspid and pulmonic valves are lower risk and less frequently needed operations. ...Read moreGet help from a doctor now ›
