[X-ray evaluation of the results of mitral valve bioprostheses]. / Rentgenologicheskaia otsenka rezul'tatov bioprotezirovaniia mitral'nogo klapana.

An analysis of results of investigations performed in 66 patients has shown that roentgenometric examinations facilitate obtaining an objective estimation of the dynamics of postoperative period in patients with bioprostheses of the mitral valve. After performing such operations many roentgenological signs of the defect undergo involution, the duration of the process being determined by the character of the defect and the initial state of the myocardium. The dynamics of volumetric alterations of the heart were shown to reflect specific functioning of the bioprosthesis.

[Late results of the surgical treatment of a postinfarct interventricular septal defect]. / Otdalennye rezul'taty khirurgicheskogo lecheniia bol'nykh s postinfarktmym defektom mezhzheludochkovoi peregorodki.

Surgical treatment of patients with post-infarction defect of the interventricular septum is highly effective. Despite the complexity and large volume of operation in this contingent of patients results of the operation are much better than in patients treated conservatively. At late periods after operation fairly high physical activity of patients is observed, which permits return to work to some of them, and to patients of pension age, enables them to do house chores, while the survived nonoperated patients are hardly capable of self-help.

[Surgical treatment of multiple heart valve defects]. / Khirurgicheskoe lechenie mnogoklapannykh porokov serdtsa.

The article deals with the study of problems of the surgical treatment of patients with multivalvular heart diseases. Problems of myocardial protection, the methods for correcting tricuspid disease, and the attitude towards attendant valvular diseases depending on their severity are discussed on the grounds of the analysis of hospital fatality rate in a group fo 505 patients who underwent one-stage correction of two or three defective heart valves and the appraisal of late results. Analysis of the late results indicates that a more radical approach to the surgical treatment of mitral valvular disease is necessary and that marked relative insufficiency and all forms of organic tricuspid disease must be corrected without fail.

[Hemodynamics and the heart volumes of patients before and after mitral valve prosthesis]. / Gemodinamika i ob'emy serdtsa u bol'nykh do i posle protezirovaniia mitral'nogo klapana.

The article deals with a complex study of parameters of the hemodynamics and volume of the cardiac cavities in comparison with a clinical state of patients suffering from mitral defect before and in different periods following prosthesis of the mitral valve. On the basis of the results obtained during examination of 54 patients there was revealed a complete conformity between their clinical state, data of the hemodynamics, the volume of the heart and left auricle. A reverse development of many signs characteristic of the defect was established. The absence of an absolute improvement of some clinical and hemodynamic indices in remote periods following the operation in a number of patients was connected with a marked increase of the cardiac volumes before the operation, an unsatisfactory contractile capacity of the myocardium, the remaining of cardiac fibrillation after the operation.

[Results of the aortic valve prosthesis with a follow-up period of over 3 years]. / Rezul'taty protezirovaniia aortal'nogo klapana pri sroke nabliudeniia bolee 3 let

The results of the aortic valve prosthetics in 71 patients discharged from the A.N. Bakulev institute of Cardio-Vascular Surgery of the AMS of the USSR as far back as three and more years ago are analyzed. All these patients had been given implanted a Soviet-made ball-type prosthesis, model AK4-02. In 5 patients some additional operative interventions were performed. No indirect action anticoagulants were used. Nine patients (12.7 per cent) died late after the operation. Good, persistent results were achieved in 48 cases (67.6 per cent) with follow-up period ranging from 3 to 9 years. Major causes responsible for a reduced effect of surgery were thromboembolic complications, paravalvular fistulas and also uncorrected or inadequately corrected concomitant failures of other valves. Ways of increasing the effective prosthetics of the aortic valve with the ball-type prosthesis are discussed.
