Foreign sources of literature regarding the issue of aortic surgery are analyzed. Special attention is paid to aortic valve replacement using the Ozaki technique. The first replacement of aortic valve cusps with synthetic material was implemented by H. Th. Bahnson in 1959; he implanted the neocusp from Teflon. Nowadays, so as to replace the aortic valve, mechanical, biological valves, homotransplants, autotransplants and valves imitated endovascularly are actively applied. All the above mentioned types of the valves have both merits and demerits, therefore each patient should have an individual approach. When choosing the prosthesis and type of surgical intervention, cardiosurgeons take into account the following factors: patients age, availability of concomitant diseases (atrial fibrillation, chronic renal disease, malignant tumors), presence of small aortic ring, aortic dilatation, availability of other valve diseases, infectious endocarditis, first or repeated surgery on the valve as well as pregnancy or planning of pregnancy. In 2007, Shigeyuki Ozaki proposed the technique for replacement of all aortic valve cusps from autopericardium treated with 0.6 % glutaraldehyde solution. This surgery permits to form the aortic valve with excellent hemodynamic characteristics and low rate of reoperation in the early and remote periods. Aortic valve replacement using Ozaki technique is a perspective technique and good alternative for surgical treatment of aortic valve along with prostheses.

Objective. To assess the efficiency and realizability of the surgical technique of aortic valve reconstruction using autologous pericardium treated by glutaraldehyde in different aortic valve diseases such as aortic stenosis, aortic regurgitation, rheumatic and degenerative diseases of aortic valve. In 2014, Ozaki presented the technique described. Materials and methods. In this work we analysed 10 cases of ministernomy combined with Ozaki procedure in patients operated at Sukhanov Federal Center for Cardiovascular Surgery. Results. No hospital mortality was registered in our study. Intraoperatively, transition to a full sternotomy was not required. A mean time of aortic cross-clamping was 84.6 ( 14.4) minutes, a mean value of artificial circulation was 103.1 ( 17.7) minutes, a mean time of ventilation was 8.4 hours, and a mean time of staying in intensive care unit room was 1.6 days. Conclusions. Minimally invasive approach combined with Ozaki procedure is realizable; it is an alternative to conventional sternotomy and should be used for patients in grave condition having concomitant diseases.
