[Circulating system for performing immersion topical hypothermia of the myocardium]. / Tsirkuliruiushchaia sistema dlia provedeniia immersionnoi topicheskoi gipotermii miokarda.

A special circulating installation for topical hypothermia of the myocardium is proposed. An advantage of the installation is the possibility of the permanent controlled irrigation of the whole surface of the heart, especially of the posterior surface represented mainly by the left ventricle mass with the ice-cold solution.

[Prognosis of the effectiveness of electroimpulse therapy of auricular fibrillation according to the roentgenocardiometric data]. / Prognozirovanie effektivnosti elektroimpul'snoi terapii mertsatel'noi aritmii po dannym rentgenokardiometrii.

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.

[Evaluation of the hypotensive effect and indications for the operation of nephropexy in patients with arterial hypertension combined with nephroptosis]. / Otsenka gipotenzivnogo éffekta i pokazaniia k operatsii nefropeksii u bol'nykh arterial'noi gipertoniei v sochetanii s nefroptozom

The results of the examination and nephropexy operation in 11 patients with arterial hypertension and nephroptosis are presented; a hypotensive effect was achieved in 5 of the operated patients; the follow-up period was up to 3 years. The recordings included the elevation of the arterial pressure in orthostasis, the changes in the urine sediment, the activity of plasma renin at rest and after 1-hour's orthostasis; excretory urography and the Seldinger abdominal aortography in a lying and upright position of the patient were conducted, as well as intraoperative biopsy of the renal tissue. Patients with a hypotensive effect exhibited a regular elevation of the arterial pressure in orthostasis, an increased plasma renin activity, congestive features in the descended kidney. The above symptoms permit to distinguish groups of patients with a hypotensive effect achieved after nephropexy, and those without effect. On the basis of the obtained results it was concluded that in some cases nephroptosis may be the cause of symptomatic arterial hypertension. In such cases it seems rational to recommend the nephropexy operation taking into account, when determining the indications for surgery, the degree of the orthostatic elevation of the arterial pressure and of the renin activity, and the symptoms of disorders in the renal evacuation function.
