What Is Valve Insufficiency?

A valve is a membrane-like structure that can be opened and closed in the organs of humans or certain animals. This article only describes the valves in the human heart. There are four valves in each person's heart. That is, the aortic valve connecting the left ventricle and the aorta, the pulmonary valve connecting the right ventricle and the pulmonary artery, the mitral valve connecting the left atrium and the left ventricle, and the tricuspid valve connecting the right atrium and the right ventricle. They all act as one-way valves, allowing blood to flow from one direction to the other and not backward.

Cyclic process:

The crispness of the heartbeat sound indicates whether the valve is closed well; the murky sound indicates the size of the opening of the valve, or whether the valve has a leak. ) The most common valve problems are

Respiratory tract infection, long-term pulmonary congestion can easily lead to lung infection, which can further aggravate or induce heart failure.

Heart failure is the most common complication and leading cause of death from rheumatic heart disease.

Arrhythmia, all kinds of arrhythmia can occur, with

Rheumatic

Artificial heart valves fall into two broad categories.

One is a mechanical flap, and the other is a biological flap.

The former is made of advanced synthetic materials, while the latter is made of both artificially synthesized advanced materials and complex chemically treated biological tissue membranes. Each has its advantages and disadvantages. The advantage of a mechanical valve is its durability, but its disadvantage is that it needs to last a lifetime

Influencing factors of valve sound include:

1) Related to making materials.

2) The angle of opening and closing and the radian across the leaflets. The larger the opening angle, the louder the noise should be. However, the main determinant is that the leaflet spans the arc when it opens, and the murmur of a double-leaflet is generally smaller than that of a single-leaflet.

3) The relationship between closing speed, specific gravity, and valve weight.

4) factors such as function and thoracic structure.

The same kind of artificial valve, when transplanted to different patients, can have different volume of murmur. Furthermore, the same patient produces different noises at different times after surgery.

Prevention and nursing

In order to protect the function of the kidneys and bladder, the best method is early detection. Ultrasound examination of the prenatal fetus should be performed, and the newborn should be carefully examined for physical examination to observe urination and test urine. Children with azotemia and prolonged urinary tract infections have a poor prognosis, even if the obstruction has been lifted.
