What is a bicuspid aortic valve?

This pathology, first of all, is a malformation of the heart, so you should not take it lightly! It is a violation of the structure of the valve leaflets, it can be both congenital and acquired, in order to answer this question exactly, it is necessary to compare the ultrasound of the heart from the very birth of the child.

Violation of the valve structure consists in the presence of only two leaflets instead of three (a truly two-leaf valve) or there were initially three leaflets and for some reason they fused together or the third leaflet is underdeveloped (functionally a two-leaf valve) and practically does not participate in the operation of the valve.

In such a situation, the function of the valve may not suffer (this is a very good option), but in some situations the operation of the valve may be disrupted either towards the narrowing of the valve opening, and then the vital organs will receive insufficient blood and oxygen and lag behind in development. In other cases, a reverse situation may occur when the valve will not close tightly and will constantly pass part of the blood in the opposite direction, thereby overloading the left ventricle with additional volume and developing heart failure.

This pathology must necessarily be observed by a cardiologist and the function of the valve by ultrasound be monitored until the child completes all critical periods of his development and intensive growth.

How bad is mitral valve prolapse?

Prolapse itself (MVP) is considered a minor anomaly in the development of the heart and may be one of the symptoms of connective tissue dysplasia syndrome. During the growth of children, during the so-called “stretching periods”, mitral valve prolapse within 5 mm appears in almost all children due to the different growth rates of various heart tissues. So the heart muscle, like all other muscles, grows much faster than the valve apparatus and can simply “stretch” somewhat both the valve flaps themselves and the chords that attach them.

In such a situation, it is important to correctly assess the operation of the valve and not miss the moment when you need to intervene. Valve operation is assessed by ultrasound of the heart, and only with the help of examination and listening, one can only establish the presence of prolapse, but not its degree.

In children with MVP, most often nothing bothers, but there may be complaints of a different nature, from simple pain in the heart area to dizziness and fainting. Therefore, a child with MVP must be monitored by a cardiologist.
