Emergent Balloon Mitral Valvuloplasty during Pregnancy

Balloon mitral valvuloplasty has been performed safely during pregnancy with good results, but maternal complications and influent fetal outcome during pregnancy still exist. Prognostic factors of rheumatic mitral stenosis during pregnancy and puerperium were the mitral valve area and functional class strongly associated with maternal complications but not associated with fetal/neonatal events. Here, we present a patient who suffered from severe mitral stenosis complicated by severe pulmonary hypertension, acute pulmonary edema, acute respiratory failure, and cardiogenic shock, and the patient improved dramatically after emergent balloon mitral valvuloplasty.
