Percutaneous mitral valvuloplasty can be performed during pregnancy without a high risk of maternal-fetal mortality. In Cuba, there was no precedent of the implementation of this technique in this kind of patients. Nine valvuloplasties were performed in pregnant women (using the Inoue method), form a total of 110 procedures carried out in a consecutive way between June 17th 1998 and June 30th 2004 at the Cardiology and Cardiovascular Surgery Institute, which were assessed up to June 17th 2009. The longest follow-up was 11 years, the minimum 6.26 years and the average 8.26 years. Before the valvuloplasty, the pregnant women were in the functional classes III and IV (New York Heart Association). The valvular areas measured by echo-planimetry were ≤1,01 cm2 . A patient presenting a valvular area of 1.52 cm2, showed after the valvuloplasty a moderated mitral insufficiency which evolved to a severe insufficiency at 26 weeks, being necessary a mitral valve replacement with no maternal or fetal complication. The other patients did not present adverse events during the long-term follow-up or any alteration in the development of the children. There was no mortality. Therefore, it can be concluded that the percutaneous mitral valvuloplasty is a feasible procedure in pregnant women with mitral stenosis and its results are maintained in the short, medium and long-run.
