The invention relates to a cardiac prosthesis fixing device made up of a
tubular element that can be accommodated inside a valve annulus of a heart
and is provided with a bottom flange and top flange, between which the
valve annulus can be accommodated. According to the invention the bottom
flange is bent, or can be bent, reversibly, against a resilient force,
from a first outward-pointing position into a second position in which the
projection of the bottom flange on a radial transverse surface of the
tubular element is located essentially on and/or within the periphery of
the tubular element and the bottom flange is fixed or can be fixed in said
second position in such a way that the fixing can be released in order to
bend back the bottom flange towards the first position under the influence
of said resilient force.
