Abstract: The present invention relates to a heterologous total stentless mitral valve prosthesis for the use in mitral and tricuspid position which provides for better hemodynamic performance. This mitral valve prosthesis addresses the specific needs of flow and contractility, thereby prolonging durability. The heterologous total stentless mitral heart valve prosthesis of this present invention comprises one sewing ring, leaflets, and subvalvar apparatus having new chordal insertions which are fixed between two heterologous pericardial patches. This heart valve prosthesis is obtained from heterologous mammals, such as swine, ovine, bovine, and moreover, the pericardial patches used may also be of synthetic material.
