[Emergency percutaneous balloon mitral valvuloplasty in a pregnant woman]. / Valvoplastia mitral percutânea de urgência em gestante.

We report the case of a 33-year-old woman in the 28th week of pregnancy and with signs of fetal death, admitted to hospital in an emergency due to pulmonary edema secondary to severe mitral valve stenosis. Intensive medical treatment was unsuccessful and the patient was submitted to an emergency percutaneous balloon mitral valvoplasty with prompt clinical improvement. Subsequent clinical deterioration secondary to fetal death was managed by cesarean section resulting in clinical establization. The patient was discharged 10 days after admission and at 11 months after the procedure she had mild symptoms without drug therapy and echocardiographic signs of mild residual mitral stenosis (mitral valve area: 2.0 cm2).
