[A new surgical approach to the membranous heart septum and a method for eliminating its defect by a closed procedure].

On the basis of an analysis of the operative wound parameters carried out in significant autopsy material it is concluded that longitudinal median sternotomy and anterolateral thoracotomy in the third intercostal right space permit reaching the upper edge of the membranous septum of the heart using the new para-aortal access. This access allows to place a suture around the septum without opening the heart cavities by the closed method which is an alternative to the open correction of the interventricular septum defect in this ares. In clinical conditions the defect of interventricular septum was completely sutured in 3 patients, partially--in 2 patients, was not sutured in 1. In one patient only on of two interventricular septum defects was closed.
