Abstract
We report two emergency mitral valve replacements performed successfully on 16-week and 29-week pregnant women for infective endocarditis in the active phase. The first patient was in severe acute heart failure on admission, and the fetus was already dead. Induced abortion was performed uneventfully 6 days after mitral valve replacement. The second patient presented with several episodes of systemic embolization. An echocardiography revealed giant movable vegetation on the mitral valve. The patient had emergency mitral valve replacement just after the Caesarian section. Both the patient and her baby weighting 1, 374g had an uneventful good courses with no complication. We concluded that in emergency operations in pregnancy, saving the mother's life should have priority over all else, but we should find the way to rescue the fetus life if at all possible. Therefore, depending on the situation, we should not hesitate about doing a simultaneous operation, Caesarian section and heart surgery, for that purpose.
