Abstract
In some cases, there are fairly coarse structural changes in the fibrous ring (FR) of mitral valve (MV), when
it is not possible to implant a prosthetic MV in a classical way (intra- or supra-annular). One of the common
causes of gross lesions of the FR of the MV is prosthetic infective endocarditis (IE), the occurrence of which
is 0.5% per year from all operations on the MV, regardless of the type of implant prosthesis. Due to the high
risk of developing a recurrent infection with prosthetic IE, excision of all pathologically altered tissues is required, which often leads to the need for reconstruction of the FR of the MV and surrounding structures.
Despite a large number of methods for reconstructing the FR, in the current literature, there is not enough
research that would fully demonstrate the effectiveness of reconstruction techniques for gross lesions of FR.
Thus, the survival rate of patients within 10 years after prosthetics of the MV with reconstruction of the FR
for prosthetic endocarditis is from 28 to 38%. The article presents a method for fixing a mitral valve prosthesis
through the interatrial septum with a prosthetic infective endocarditis with destruction of the “anterior”
fibrous ring.
