[Evaluation of the results of closed mitral commissurotomy in the early and late periods after surgery, based on data from a complex echocardiographic examination].
A study of early and late results of closed mitral commissurotomy demonstrated a 1.8-fold increase in two-dimensional mitral opening area, as compared to preoperative data, largely due to an increase in intercommissural diameter, with intercuspid diameter only slightly changed. In most cases, the operation was not conducive to complete recovery of the mitral opening area that averaged 3 cm2. Impulse doppler-echocardiography showed a 2.1-fold postoperative decrease in diastolic blood pressure gradient. The operation was less effective in cases of mitral calcinosis. One-dimensional investigation demonstrated an insignificant postoperative variation in Vef of the mitral anterior cusp.
