The hemodynamic effect of closed mitral recommissurotomy based on data from manometry in the heart chambers and from echocardiography

: The work analyzes causes of high blood loss in operations under conditions of nonperfusion deep hypothermia. It was found to be related with the division of massive adhesions in the preocclusive period and with the presence of prolonged heparinemia after occlusion. A combination of a minimal trauma of adhesions, reliable surgical hemostasis, early suturing the wound of the chest and early neutralization of activity of heparin allowed the operation blood loss to be 2.4 times less and the postoperative blood loss--2.7 times less.
