They choose to mount the valves on systema skeletale or flexible stent . Later on , they enshroud the bottom part of the several valve by using a seamlessly knitted polytetrafluoroethylene fabric . This material is helpful in healing operation and in - increment of the tissue paper across the engraft valve .
In this manner , cardiac surgeons regale the valve chemically for preserve the tissue paper and foreclose immunological reaction after placing it in a affected role . cause behind applying this technique is that heart valve of humans and that of pigs have huge law of similarity based on both function and structure .
Because of this , the pig valve replacement method is more common than the cow cardiac tissue transposition one . Thus , with the assist of pig warmness valves , i.e. tissue valves , you may fend off taking blood thinner medication for your lifespan .
Why Pig Heart Valve Replacement?
Whenever compression of heart takes plaza , it expels the rakehell within the arterial circulation with the help of aortic valve . Significant abnormality in this case is that the newly replaced valve may interfere with the menstruum of parentage in man .

Longevity of the Pig Heart Valve Placed in Humans:
We may judge the longevity associate with slob heart valve replacement operating theatre in human existence based on the stick to central professional and cons of the adopted proficiency .
Pros of the Transplant Surgery
Cons of the Transplant Surgery
Major drawback associated with pig heart valve successor is that slovenly person valves fail to last for a long time . Because of this , medico often implant fuzz valves in patients exceeding 60 years age . base on detailed research reports provided by top cardiologists / cardiac surgeons worldwide , the biological valves i.e. pig valves last for about 15 years to 17 year only .
