    摘要: A natural tissue heart valve includes a tubular wall having an outflow section and valve leaflets which allow flow into the outflow section. A heart valve of this type is subjected to a fixative fluid to provide a first differential fluid pressure across the tubular wall of the outflow section and a second differential fluid pressure across the valve leaflets. The first differential fluid pressure acts outwardly on the tubular wall, and the differential pressures are unequal.
