We report a case of emergent redo-mitral valve replacement during pregnancy at 23 week and 4 days of gestation. A 23-year-old woman, who underwent mitral valve replacement with a bioprosthetic valve(Carpentier-Edwards Perimount®27mm)for infective endocarditis 5 years ago, was transferred to our hospital due to severe congestive heart failure. Echocardiography revealed structural valve deterioration of the mitral prosthesis and severe mitral stenosis. Emergent redo-mitral valve replacement with a bioprosthetic valve was performed to save the patient with top priority. Cardiopulmonary bypass was operated under normothermic, high flow, high pressure and pulsatile fashion. Fetal heart rate was continuously monitored during the operation. Although her baby was delivered vaginally just after operation weighing only 520g, she was treated by the neonatologists successfully.
