“…Due to the special properties of this material, gauges can be modeled, giving them the desired shape and allowing more convenient measurement of the distance between the commissures, then they are also used as templates for cutting the leaf. In addition to improved meters, Benaki's operation uses special "three-armed" forceps for the comfort of creating aortic valve neocusps [7].

“…Performing neocuspidization according to the formulas is possible only in the absence of aortic root expansion (the diameter at the level of the sinotubular junction is not more than 35 mm and the diameter at the level of the fibrous ring is not more than 25 mm). Otherwise, it is necessary to perform neocuspidization in combination with aortic root replacement in the Moscow (Russian) conduit modification [7,8].…”

Acquired heart disease – the concept of “acquired heart disease” includes a variety of pathological conditions acquired during the life of the patient. The lion’s share of these diseases are acquired heart defects. The significance of this problem is special for our region, since the incidence of rheumatic diseases and its complications in our Republic is still significant. However, in recent decades, statistical data on acquired defects, especially on aortic heart defects, have changed markedly. Thus, the prevalence of aortic heart disease among the elderly and senile is about 10.7%, significantly increasing for sclerotic lesions of the aortic valve – up to 25–48%. According to Euro Heart Survey on valvular heart disease, damage to the aortic valve was detected in 44.3% of patients with valvular heart disease (33.9% – aortic stenosis, 10.4% – aortic valve insufficiency. At the same time, aortic stenosis in 81.9% and insufficiency – in 50 .3% of patients were of degenerative origin. According to the statistics of our Republic, more than 400 patients with rheumatism per 100 thousand of the population are detected per year, of which, after an appropriate examination, in terms of the population of our Republic, more than 16,000 require surgical correction of acquired heart disease, which confirms the importance of discussing the problem for our healthcare.

“…Основным методом лечения данной патологии является хирургическая коррекция порока, позволяющая восстановить нормальные гемодинамические параметры в организме человека. Хирургия клапана аорты начала развиваться еще в 1910 году в эпоху до появления искусственного кровообращения, с момента выполнения закрытой комиссуротомии пациенту с декомпенсированным пороком [3]. За прошедший век методы лечения патологии совершенствовались и модифицировались: появились искусственные клапаны, начали использоваться в практике гомотрансплантаты и аутотрансплантаты, адаптировались к применению рентгеноэндоваскулярные методы замены клапана.…”

Successful reconstruction of the aortic valve requires the preliminary creation of the anatomical design of its image, which includes a set of parameters of the valves of a particular valve. Errors in operation at the stage of design of valve components are fraught with subsequent dysfunction. In the present, the optimal sizes of the aortic root and the valves of the aortic valve were evaluated and the presence and values of correlations between them were determined. Statistically significant anatomical and functional correlations of morphometric characteristics of aortic root structures were revealed to achieve the optimal level of their correspondence in autologous grafts during surgical correction of the aortic valve. The main morphometric parameters of the aortic root were analyzed on the example of 54 samples obtained post mortem from patients whose death occurred from causes not associated with heart disease. The cases with aortic valve disease were excluded from the study. The following parameters were evaluated: circumference of the ventriculo-arterial junction; circumference of the sinuses of Valsalva; circumference of the sinutubular junction. Separately, for each of the three cusps of the native aortic valve, were evaluated: the length of the free edge of the cusp (L1); the length of the junction of the leaflet and the fibrous ring of the aortic valve (L2); leaflet height (A); intercommissural distance (IC). A search was made for the correlation between the size of the valves and the parameters of the circumference of the aortic root at the level of the ventriculo-arterial junction, of the sinuses of Valsalva and of sinutubular junction. A significant presence of a correlations was found between all parameters of the aortic valve cusps and the length of the aortic circumference at the level of the ventriculo-arterial junction, of the sinuses of Valsalva and sinutubular junction (r>0.6 for IC, L1, L2 and r>0.5 for A at p<0,01). The data obtained by correlation analysis make it possible to standardize the design of the autograft of the aortic valve, thereby ensuring the best coaptation of the valves and, as a result, the function of the aortic valve.
