ABSTRACT
A soft synthetic semi-ring was used in reconstructive-plastic operations on 36 patients with rheumatic mitral insufficiency; it was sutured in the projection of the posterior cusp. The operative techniques and the immediate results are described. Lethality was 5.5%.

Nineteen patients suffering from congenital heart diseases were examined by means of the apparatus Pneumoscreen manufactured by Eger Company (FRG) and the mechanocardiograph H-106 designed by N. I. Savitsky, which synchronously recorded the curves of the volumetric speed of the flow and intrathoracic pressure. Analysis was made of the relationship of the magnitude of the instant maximal velocity characteristics of forced expiration in all lung capacities and their time-course of changes to the total pulmonary resistance. It is revealed that the decrease of the maximal velocity characteristics of forced expiration in large pulmonary capacities was directly proportional to the degree of pulmonary tissue rigidity in patients with congenital heart diseases and corresponded to the degree of hemodynamic disorders in pulmonary circulation. The fall of the instant velocity of forced expiration in small lung capacities in patients with congenital heart diseases evidences not only the presence of bronchial obstruction but also high total pulmonary resistance.

Experience in surgical correction of aortic valvular disease with extreme calcification of valves in 145 patients is generalized. The method for valve prosthetics preventing the development of specific complications is described. On the basis of analysis of the immediate and late postoperative results, it is recommended to use cold cardioplagia for protection of the myocardium. Hospital postoperative mortality was 13.9% in the last 4 years and 10.5% in the last 18 months. Preliminaly coronarography is suggested for the examination of patients with marked angina pectoris and with local changes on the ECG in the group of elderly patients for ruling out a concomitant organic lesion of the coronary artery.
