Imported heart biomembranes include xenograft valves and homograft valves, which are analyzed as follows.
1. Heterotopic valves: these valves are mainly taken from pigs or cows, respectively, pig aortic valve and bovine pericardial valve two, the patient for the compatibility of such valves is not good, easy to rejection, but such valves donor is more, so clinically used more.
2. Homograft valves: including fresh homograft dura mater valves, homograft aortic valves, and autologous broad fascia valves, the patient’s compatibility with such valves is more, and seldom appear rejection, but the donor is relatively small, so the use of the clinic is also relatively small.
Generally speaking, the effectiveness of biologic valves is much greater than that of mechanical valves, and choosing a biologic valve will help improve the patient’s life expectancy and reduce the patient’s pain.
If you need heart valve replacement, please consult the hospital in time and choose the appropriate program under the guidance of the doctor to avoid adverse consequences.
