infective endocarditis is rare during pregnancy, more common in pregnant women with valvulopathy or congenital heart disease, its diagnosis may be delayed due to atypical clinical presentations, the prognosis is marqued by high maternal and fetal morbidity and mortality due to a high complication rate, management is often difficult and needs to be adapted on a case-by-case basis. We report the observation of a young pregnant patient admitted for mitral infective endocarditis complicated by multiple embolisms and a haemorrhagic stroke by rupture of mycotic aneurysm whose evolution was fatal.
