Prospects of development in aortic surgery: literature review

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: patient’s 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.
