[Cardiac abscesses].

The paper analyzes the experience in treating 75 patients with cardiac abscesses of various sites. Abscesses complicated the natural history of infectious endocarditis in all patients. The clinical features of cardiac abscesses are shown to be related to the stage of the destructive process. Echocardiography, follow-up analysis of ECH, PhCG and overall clinical data are demonstrated to play a role in their diagnosis. The paper discusses the specific features of surgical intervention into the heart if abscesses are present. Out of 75 patients who have been operated on for abscessing infectious endocarditis, 53 have had an operation and survived.

[Intensive plasmapheresis: complications and their prevention].

Upon the analysis of 246 plasmapheresis sessions performed for autoplasma provision, the correction of the blood rheology and the decrease in endogenic intoxication of 216 patients, it was stated that the frequency of various reactivity and complications comprised 12.9%. The causes of these complications and the means of their prevention were analyzed.

[Possibilities of predicting the outcome of diseases after cardiosurgical interventions].

A multifactorial correlation and regression analysis with the use of a pack of applied programs "SAND" in the computer SM-4 was performed for prognosis of the outcome of the disease in 38 patients with acquired heart diseases operated upon under conditions of extracorporeal circulation. A linear mathematical model was obtained which allowed predicting the course of the postoperative period and outcome of the disease of cardio-surgical patients with 70-80% probability.

[The surgery of suppurative-septic diseases of the heart: its characteristics and outlook].

An analysis of the experience with surgical treatment of more than 320 patients with infectious endocarditis has shown the necessity to isolate pyo-septic cardiosurgery into an independent line. The arguments are: the specificity of the contingent of patients, special features of diagnosing, operative technique and period of rehabilitation, sanitizing regimen of the artificial blood circulation and others. The organizational aspect includes the necessity of active surgical tactics in treatment of pyo-surgical foci of cardiac localization. Successful treatment of this category of patients can be performed due to the availability of special antiseptic centers which must closely cooperate with cardiosurgical departments functioning in the regimen of emergency diagnostics and cardiac surgery.

[Plasmapheresis and the immune system in heart surgery patients].

An analysis of results of investigation of the influence of apparatus plasmathrombocytopheresis on the immune status of 29 patients with heart diseases is presented. It was shown that intensive plasmapheresis was not followed by substantially decreased level of IgA, IgM and C3 fraction of the complement. The curative effect of this operation in cardiosurgical patients manifests itself as decrease of the level of circulating immune complexes.

[Surgical treatment of septic endocarditis in drug addicts].

The clinical picture of endocarditis in addicts is characterized by mainly right-sided localization of the process in the heart, poor auscultatory picture of the heart, pleuro-pulmonary manifestations against the background of a feverish course of the disease. The leading role in diagnosis of infectious endocarditis in addicts should be given to echocardiography. A description of three cases of surgical treatment of infectious endocarditis in addicts is presented.

[Use of cryopreserved autologous thrombocytes in cardiac surgery].

Cryopreserved autologous thrombocytes were used for the prevention of thrombohemorrhagic complications after operations with extracorporeal circulation in 17 patients. An obvious hemostatic effect was produced. Studies carried out in cardiosurgical patients showed satisfactory maintenance of the main hemostatic characteristics of the blood platelets during cryopreservation. Plasma thrombocytapheresis in an apparatus allows simultaneous preparation of the autothromboconcentrate and large amounts of autoplasma used for filling the extracorporeal circulation apparatus, and compensation for the blood loss.
