[Heart valve involvement in lupus erythematosus disseminatus. Apropos of 2 cases. Review of the literature].

Regarding two cases of idiopathic lupus valvulopathy, the authors review the various mechanisms responsible for the endocardial lesions in disseminated lupus erythematosus. In addition to the classic Libman-Sachs endocarditis, there are sclerous forms, ruptures of the chords, thromboses and bacterial superinfections. The role of steroid therapy in the genesis of valvular stenosis is not always determined. A surgical treatment, effective and without major risk, must be advocated at an early stage in the presence of poorly tolerated forms.
