[High-tone therapy in complex rehabilitation of patients with post-sternotomy syndrome after coronary artery bypass surgery. (Open-label, prospective, randomized controlled trial)]. / Vysokotonovaya terapiya v kompleksnoi reabilitatsii bol'nykh s poststernotomicheskim sindromom posle aortokoronarnogo shuntirovaniya. (Otkrytoe prospektivnoe randomizirovannoe kontroliruemoe issledovanie).

INTRODUCTION: At present it remains relevant to develop new rehabilitation technologies for patients with circulatory system diseases who have undergone a cardiac surgery to restore the functions of the cardiorespiratory system more quickly, improve physical and mental health, and prevent the development of the atherosclerotic process. AIM: To study the effectiveness and safety of the new rehabilitation technology for the inpatient stage of medical rehabilitation of patients with post-sternotomy syndrome after coronary artery bypass surgery (CABS) using high-tone therapy. MATERIAL AND METHODS: The study included 85 men (the average age was 56.8±2.46 years old) with post-sternotomy syndrome after CABS. They were divided into two groups by simple randomization: the first/main (42 patients) and the second/control (43 patients). The control group of the patients had a standard rehabilitation complex; the main group was additionally prescribed a high-tone therapy according to a local method. The immediate results of the treatment were assessed by the dynamics of the clinical picture, the six-minute walk test, respiratory function, echocardiography, the level of cytokines, C-reactive protein and natriuretic peptide (NT-proBNP); distant - by QOL endpoints (questionnaire MOS SF-36). RESULTS: The groups of the patients were comparable in all baseline parameters. After the course of the procedures in the main group of patients there were positive reliable (p<0.05-0.001) shifts in clinical (pain, shortness of breath, general weakness), functional (forced expiratory vital capacity, forced expiratory volume1, effusion separation) and laboratory parameters (leukocytes, interleukin-2 and 10, NT-proBNP). The intergroup analysis of long-term results registered significant (p<0.05) differences in the QOL of patients in the main group by subscales: the role of somatic problems, vitality and mental health. Compliance to the III stage of medical rehabilitation (outpatient/home) was noted with 95.2% of the patients in the first group and 93.0% in the second. CONCLUSION: The additional appointment of a high-tone therapy to the rehabilitation standard for the patients with post-sternotomy syndrome after CABS significantly improves the immediate and long-term results of the treatment (QOL) contributing to a more pronounced reverse development of inflammatory and edematous syndromes, an increase in physical activity and psychosomatic health. The absence of adverse reactions with all the patients indicates the safety of rehabilitation complexes.

[Evolution of mitral valve replacement]. / Évoliutsiia protezirovaniia mitral'nogo klapana.

Historical development of mitral valve surgery at Petrovsky Russian Research Center for Surgery is described in the article. Evolution of artificial heart valves design and development of surgical techniques are presented.

[Decalcification of anterior cusp of mitral valve at marked calcification of aortic valve].

Short-term and long-term results of surgical treatment were analyzed in 108 patients with aortic valve disease, complicated significant calcinosis spreading on anterior cusp of mitral valve. Mean age of the patients - 53,5±10,8 years (from 25 to 88 years). All patients underwent aortic valve replacement and decalcification of anterior cusp of mitral valve. Coronary bypass grafting was additionally carried out in 10 cases (from 1 to 5 shunts, 1,9 - in average). Hospital lethality was absent. Functional improvement of mitral valve was observed basing on postoperative echocardiography and remained in long-term period.

[Preservation of subvalvular mechanism at mitral valve replacement].

According to literature data there is no common approach to method of mitral valve replacement with preservation of subvalvular structures. Results of 175 operations of mitral valve replacement are analyzed. The preservation of fibrous-papillary contact must not be regarded as the goal itself, but it must improve the clinical effect of operation. Further study of left ventricle remodeling at mitral valve disease and repair of physiological function after surgery permits to predict and improve the functional results in early and long-term postoperative period.
