durability: A comparison between Hancock standard and Hancock II bioprostheses.
Examination of the extracted bioprosthetic valve revealed devitalized porcine valve
with rare mononuclear cells on the surface of the leaflets (Figure 1, A and B).
In several studies, by 15 years the porcine valve
has failed in 30 percent to 60 percent of patients.
The type III tear was an oval perforation at the center of one cusp of a Carpentier-Edwards porcine valve
, measuring 0.

Second-generation pericardial valves are more durable than traditional porcine valves
as aortic valve replacements, said Guangqiang Gao, M.
Mechanical valves appear to be superior to porcine valves
in patients undergoing mitral or aortic valve replacement, according to Dr.
