Balloon valvuloplasty during pregnancy

Although rheumatic diseases are reported to be almost eradicated in the developed countries, they still continue to contribute significantly to maternal mortality in the developing world. Surgical therapies need to be considered for those patients who do not respond satisfactorily to medication. However, valve replacement or valvulotomy during pregnancy carries significant risks for both the mother and the fetus. Two patients with severe mitral stenosis refractory to medical therapy are presented. Both patients were subjected to percutaneous balloon valvuloplasty during pregnancy without any complications. They were able to discontinue medication and deliver vaginally at term. Balloon valvuloplasty appears to be a safe alternative to conventional surgical approaches in pregnancy.
