Ultrasonography of heart
Ultrasound examination of heart (ultrasonography of heart) is the tool way of a research of heart allowing to reveal a large number of various pathologies which can meet at any age. Sometimes mistakenly it is considered that it is necessary to do ultrasonography of heart only to reveal inborn malformations of heart. Actually ultrasonography of heart allows to reveal a big range of various diseases in addition to inborn defects. Ultrasonography of heart very informative technique of a research allowing to obtain information not only on a condition of valves, but also the sizes of cardial cavities, existence of pathological blood flows, work of a cardiac muscle. This technique differs not only the informational content, but also full safety. Therefore performing ultrasonography of heart to the newborn and ultrasonography of heart at pregnancy is possible that in any way on health neither mother, nor the child will be reflected.
Indications for performing ultrasonography of heart
Indications for ultrasonography of heart can be both planned, and emergency.
The heart research at teenage age and before pregnancy belongs to planned indications. All teenagers at the age of 14 years are recommended to make ultrasonography of heart. Need of carrying out this research for this age is caused by the fact that teenagers begin to grow intensively. The organism grows unevenly: some bodies grow quicker, some more slowly. The cardiac muscle does not differ in a possibility of intensive growth therefore in the period of the increasing loads of a myocardium emergence of pathological processes in heart is possible.
If to speak about pregnancy, then need of performing ultrasonography of heart is caused by the fact that pregnancy increases load of cardiovascular system. For this reason if in a structure of heart any anomaly which was not diagnosed at earlier stages of life of the woman was observed, it can influence pregnancy course. It leads to disturbance of normal life activity of the woman therefore there can be a question of abortion. It is also possible to carry out ultrasonography of heart and at pregnancy if the woman has a chronic heart disease, and the research was not conducted in advance. Ultrasound does not make any impact on the developing fruit.
The raised exercise stresses can also affect a condition of heart therefore the people who are professionally playing sports have to do ultrasonography of heart periodically.

Also happens small children who are negative to this procedure cannot make ultrasonography of heart.
Technique of performing ultrasonography of heart
Ability of fabrics with various density differently is the cornerstone of performing ultrasonography of heart to reflect ultrasound. Sensors of the device catch ultrasonic waves which are reflected from heart and build the picture of the received results on the screen. Informational content of the received picture depends on degree of sensitivity of sensors. There are various nozzles on sensors which allow to expand information obtained when performing ultrasonography of heart. With use of similar sensors there is an opportunity to observe the movement of blood in cardial cavities that it allows to diagnose regurgitation (the return blood flow).
Diseases and states which can be diagnosed when performing ultrasonography of heart
Ultrasonography of heart at newborns allows to reveal malformations of heart and its anomaly. By means of ultrasonography of heart it is possible to diagnose insufficiency of cordial valve system, existence of the return blood flow, defeats of valves at an endocarditis are diagnosed.
