[Percutaneous mitral valvuloplasty during pregnancy].

The mitral valve stenosis is the most frequently valvuloplasty in pregnant patients. When it carries a significant risk of mortality for both mother and fetus, it can be performed a surgical commissurotomy, with a high risk for the fetus. We report our experience in percutaneous mitral valvuloplasty (PMV) in 3 patients during the third trimester of pregnancy with severe mitral stenosis. In this cases, we performed PMV in NYHA (New York Heart Association) CF III patients refractory to medical treatment. We used the transseptal double balloon technique protecting the abdominal wall using a lead apron. The mitral areas increased from 1 to 2 cm2, without a significant development of mitral regurgitation. In all cases, the infants delivered at term without complications and with normal weight. The PMV arise like an ideal intervention for the treatment of mitral stenosis during pregnancy.
