ABSTRACT:
A whole heart is collected shortly after the death of the animal. The left ventricle and left atrium of the animal heart is sectioned and exposed thereby exposing the mitral valve, the chordae tendineae and the papillary heads. The mitral valve is fixed in situ by fixing portions of the left ventricle and left atrium containing the mitral valve. The mitral valve is excised from the animal heart remnant to include a portion of the endocardium containing the papillary heads and the annulus. In the preferred embodiment of the invention, the excised mitral valve is further fixed to complete fixation of the papillary heads. Then, the excess myocardial tissue is trimmed away and the mitral valve is stored in fixing solution to await further processing.
