The incidence of gonorrhea has decreased substantially in the past decade. Disseminated gonorrhea is more common in women than in men, although gonococcal endocarditis is more common in men. Disseminated gonorrhea is most commonly described in women during menses or pregnancy. Only two cases of gonococcal endocarditis during pregnancy have been reported in the literature since 1942. We report a patient who experienced sudden hemodynamic decompensation at 30 weeks' gestation, resulting in fetal death. Aortic valve replacement was performed, but extensive involvement of the aortic root made complete eradication of infection impossible and eventually resulted in maternal death.
