Mitral Prosthesis Insertion for Functional Mitral Regurgitation: Indications and Results

Mitral regurgitation (MR) is the most frequent valvulopathy in the general population (up to 9.3% in the elderly). The main pathogenesis is “functional” and this is a negative prognostic factor for both survival or occurrence of heart failure. Hence, the presence of moderate or more functional MR has to be always treated. There is general agreement that overreductive mitral annuloplasty. Nevertheless, the evolution of MR after surgical correction is not always favorable. In patients with high grade of papillary muscles displacement, mitral prosthesis insertion should be preferable to mitral repair, taking in account the preservation of the mitral apparatus. In conclusion, the surgical treatment of functional MR has to be tailored in order to offer the best option for every single patient
