Introduction: Mitral stenosis (MS) is the most common type of valvular heart disease leading
to maternal and neonatal complications. Balloon mitral valvuloplasty (BMV) is considered as a gold
standard treatment for severe MS which does not respond to medical therapy. This study reports a case of
emergent balloon mitral valvuloplasty during pregnancy.
Case Report: A 35 year-old pregnant woman, G2L1 at 38th weeks of gestation was referred was referred
because of dyspnea and orthopnea. Echocardiography revealed Severe MS, Mitral valve area of 0.9 cm
and pulmonary artery pressure (PAP): 80 mmHg, ejection fraction (EF): 40%. Urgent BMV was planned.
Delivery was carried out 4 hours after BMV without any maternal and neonatal complications.
Conclusion: BMV is a safe and effective procedure for the treatment of severe mitral stenosis in
pregnancy, even in emergent situation.
