OBJECTIVES: We sought to compare the maternal and fetal outcomes of @entity1 with severe @entity4794 submitted to percutaneous @entity384 versus open mitral valve commissurotomy (MVC) during pregnancy. BACKGROUND: @entity712 in @entity1 with @entity4794 complicating pregnancy is a common problem in developing countries. Since 1984, percutaneous dilation of the mitral valve using a balloon catheter has become a therapeutic alternative to open heart surgery. Although the efficacy of percutaneous mitral @entity384 is well established, its results have never before been compared with the results of commissurotomy during pregnancy. METHODS: We compared the clinical and obstetric complications in 45 @entity1 who were treated with percutaneous mitral @entity384 (group I, n = 21; from 1990 to 1995) or open MVC (group II, n = 24; from 1985 to 1990) for severe @entity712 due to @entity4794 during pregnancy. RESULTS: In our study, percutaneous @entity384 of the mitral valve had a success rate of 95% (Gorlin formula) and 90.5% (echocardiographic "pressure half-time" method), as demonstrated by the final mitral valve area achieved. This improvement was followed by a marked decrease in the mitral valve gradient, left atrial pressure and mean pulmonary artery pressure. @entity1 in both groups had similar improvements in symptoms. @entity1 who underwent percutaneous @entity384 had significantly fewer @entity2241 , with a reduction in fetal and neonatal mortality (1 death in group I vs. 8 in group II, p = 0.025). CONCLUSIONS: @entity661 is safe and effective and appears to be preferable for the fetus, compared with open MVC during pregnancy.
