The purpose of the work was to investigate the relationship between immediate results of the electroimpulse therapy and such roentgenocardiometric data as the voloume of the heart, the cardio-thoracic index, Moore's coefficient, the extent of the left atrium enlargement and of the radius of the contrasted esophagus deviation. An analysis of the experience gained with 197 defibrillation of the heart in patients with rheumatic heart diseases complicated by auricular fibrillation bears proof to a high degree of reliability achieved through inclusion of roentgenocardiometric data in prognosing the resultant effect of the electroimpulse therapy.

[Interstitial microfibrils in the myocardium in rheumatic and congenital heart defects].

Electron-microscopic and electron-histochemical studies of biopsies of the myocardium from the patients suffering from rheumatic and congenital affections of the heart showed that hyperplasia of aperiodic argyrophilic and ruteniophilic microfibrillae served as the ultrastructural equivalent of coarsening of the reticular frame of the hypertrophic myocardium. Relapse of the rheumatic process is accompanied by irregulation and possibly by an increase in the number of microfibrillae due to their accelerated neoformation and defibrillation of the collagen fibrils with a periodicity of 640 A. There was traced no direct relationship between the amount of microfibrillar material on the surface of the muscle cells and the extent of destruction of their organellae; this, however, did not exclude the possible interrelation between the myocardial insufficiency and hyperplasia of the myofibrillae as an integral component of fibrosis and sclerosis of the myocardium.

[Operative and postoperative neurological complications in heart surgery].

Intraoperative and postoperative neurologic complications in cardiosurgical patients refer to grave cerebral affections which aggravate markedly the operative issue and prognosis for patients' life. In 525 operations on the heart and major vessels neurologic complications were noted in 47 patients. In 21 of them death was directly caused by these complications. The character of cerebral lesions (brain hypoxia, acute disorders in the cerebral circulation) and their frequency were conditioned by the kind of operative interventions and characteristic features of the cardiovascular pathology. Routine prophylactic measures and their results are described.
