Abstract:
The presented scientific work presents a comparative analysis of
echocardiographic parameters in healthy babies and babies born with congenital
heart defects.
Key words:
congenital heart defect, EXOKG examination, white defects, blue
defects.
Relevance of the topic
Reducing infant mortality in the world is one of the important tasks of the
health care system at the state level. In recent years, the rate of births with congenital
heart defects among children has been increasing. Currently, congenital heart disease
is distinguished by its high prevalence and high mortality compared to other
developmental defects in children. In medicine, cardiovascular diseases are one of the
main causes of disability and death [1,5].
According to the World Health Organization (WHO), 56% of all deaths are
caused by cardiovascular diseases. Cardiovascular diseases cause 4.3 million (48%)
deaths per year in European countries. The rate of birth with congenital heart defect
in America from the Nordic countries is 8.2/1000 live births [4,6].
Among CHD, ventricular septal defect is the most common, and in the general
structure there are children with isolated VHD in 20% of cases. About 90% of small,
hemodynamically insignificant muscle defects have been identified to close
spontaneously by the age of 10 months. In terms of size, VHD can be small (up to 4
mm) and wide. In 30 - 50% of cases, VHD is complicated by the development of high
pulmonary hypertension (PH), which is progressive. This pressure in the pulmonary
artery is independent of the diameter of the patent arterial passage [3,7,2].

The purpose of the study.
Comparative analysis of echocardiographic
indicators in babies born with congenital and congenital heart defects in Bukhara
region.
Research materials and methods
In this paper, an analysis of echocardiographic examination of healthy and
congenital heart defects in Bukhara region is presented. For the purpose of
investigation, 48 healthy children and 23 children born with congenital heart defects
were conducted.
Research results
In infants, the width of the aorta varies from 7.1 to 11.3 mm, the average is
9.7±0.29 mm, the width of the left ventricle is from 9.1 to 12.0 mm, the average is
10.4±0.20 is mm. In infants, the thickness of the wall of the right ventricle varies from
6.1 to 12.2 mm, the average is 9.5±0.42 mm, the thickness of the interventricular
septal wall varies from 2.6 to 5.4 mm, the average is 4.0± 0.19 mm, end-diastolic size
from 7.0 to 12.0 mm, average 9.6±0.35 mm, left ventricular posterior wall thickness
varies from 5.0 mm to 9.0 mm, average - 7.0±0.28 mm, end systolic size from 3.0 to
6.4 mm up to 4.6±0.23 mm on average.
In children of the same age, the ejection fraction of the heart varies from 54.3
to 75.0%, the average is 62.0±1.44%, the end diastolic volume is from 2.5 to 6.5 ml,
the average is 4.4±0. 28 ml, the end-systolic volume varied from 1.40 ml to 2.0 ml,
average - 1.62±0.04 ml, stroke volume varied from 5.2 ml to 8.8 ml, it was found that
the average was -7.2±0.25 ml.
In infants, the number of heart contractions varies from 66.0 to 138.0, the
average is 108±5.04, the blood circulation speed in the pulmonary artery is from 1.15
to 1.86 m/s, the average is 1.40±0.04 m/s, and the speed of blood circulation in the
mitral valve is 0.62 to 1.40 m/s varies up to m/s, average - 1.0±0.05 m/s, blood
circulation in the tricuspid valve varies from 0.70 to 1.30 m/s, the average is -1.0±0.04
m/s, in healthy children of the same age, blood circulation in the aorta is from 1.0 to
1.58 m/s , on average - 1.30±0.04 m/s, the width of the base of the lung stem is from
6.4 to 12.0 mm, the average was 9.6±0.39 mm.

In babies born with congenital heart defects, the width of the aorta varies from
10.0 to 14.0 mm, the average is 11.3 ± 0.36 mm, the width of the left ventricle is from
11.0 to 13.0 mm, the average is 11. It is 7±0.18 mm. In boys born with congenital
heart defects, the thickness of the wall of the right ventricle varies from 9.6 to 11.5
mm, on average - 10.6±0.17 mm, the thickness of the interventricular septal wall
varied from 5.0 to 6.0 mm, with an average of -5.4±0.09 mm, and the end-diastolic
size was from 12.0 to 14.0 mm, with an average of 13.0±0.18 mm, the width of the
posterior wall of the left ventricle varies from 4.0 mm to 5.0 mm, the average - It was
4.5±0.09 mm, the last systolic size was from 6.0 to 10.0 mm, and the average was
7.5±0.36 mm.
In children of this age, the ejection fraction of the heart varies from 75 to
89.0%, the average is 82.6±1.28%, the end diastolic volume is from 4.0 to 8.0 ml, the
average is 5.5±0.36 ml , the final systolic volume varies from 1.0 ml to 4.0 ml, the
average - 2.4±0.27 ml, the stroke volume varied from 3.0 ml to 5.0 ml, and the average
was -3.9±0.18 ml.

to 3.0 m/s, the average is 2.33±0.10 m/s, and the speed of blood circulation in the
mitral valve is 1.40 to 1.07 m/s varies up to m/s, average - 1.24±0.03 m/s, blood
circulation in the tricuspid valve varies from 0.97 to 1.09 m/s, on average -1.01±0.01
m/s, blood circulation in the aorta in children of the same age ranges from 1.13 to

Summary
The results of our research showed that the analysis of echocardiographic
indicators of healthy and children born with various forms of congenital heart defects
proved that the echocardiographic indicators of children born with congenital heart
defects were greater than the echocardiographic results of healthy children. This
shows that children with congenital heart defects have an enlarged heart.
