The ventricular septum is underdeveloped during the fetal period, what is the cause of the neonatal

Ventricular septal defect in children with congenital heart disease is mainly caused by the dysplasia of the ventricular septum in the embryonic stage of children, which is the most common congenital heart disease in the child stage. When the damage is large, the left-to-right shunt is large, and the patient is more stunted in growth and development, has no weight gain, has weight loss, feeding difficulties, sleepiness after activity, chest tightness and shortness of breath, easy to sweat, is prone to continuous respiratory tract infection, acute bronchitis, and is easy to cause congestive energy exhaustion.

Many parents of children with congenital heart disease ventricular septal defect are confused about what are the main causes of ventricular septal defect in their children

The key judgment of the baby's ventricular septal defect is early pregnancy, because the fetus is born with incomplete development of capillaries in the heart, and the ventricular septal defect caused by the fetus is also very likely to be related to genetic inheritance. In addition, it is possible that in the early stage of pregnancy to get the virus infection or germs, seriously affect the normal development of the fetus, if you take the medicine without authorization, you can also digest and absorb through the embryo, affecting the fetus.

The main causes of ventricular septal defects in babies are as follows:

1. Fetal heart development is affected by external factors, such as pregnant mothers infected with viruses and germs during pregnancy, especially within 12 weeks;Then the chance of the baby suffering from congenital heart disease is very high.

2. Factors of the pregnant mother itself, such as taking fetal drugs, weak nutritional status, suffering from air pollution and diffusion, etc

3. Congenital factors can cause the inheritance of genes in the next generation, but the share is relatively small. However, according to Chinese and foreign data, if the mother's first child is ventricular septal defect, the probability of the second child is about four times that of the normal population. In addition, the incidence of cardiovascular and cerebrovascular disease malformations in children of patients with congenital heart disease is significantly higher than that of ordinary pregnant mothers, which indicates that congenital heart disease has a certain relationship with genetic inheritance.

Others, such as exposure to excessive doses of radiation during pregnancy, the use of some drugs, metabolic diseases or chronic diseases, insufficient oxygen, and maternal age, are all at risk of congenital heart disease.

Genetic inheritance: Most congenital heart diseases are inherited from both single and polygenic defects, which may be caused by genetic mutations or chromosomal malformations.

It is possible that the mother was infected during pregnancy, or was exposed to radiation, or it may be genetic, so this situation occurs.

External disturbances include infection with viruses and bacteria during pregnancy, maternal factors, tocolytic drugs, poor maternal nutrition or exposure to radiation, etc.

Answer] :d ventricular septal defect is caused by the left ventricular pressure being higher than that of the right ventricle, and the shunt caused by the ventricular septal defect is a left-to-right shunt, which can lead to a decrease in systemic blood volume, which is manifested as growth retardation, emaciation, fatigue, excessive sweating, feeding difficulties, chest tightness, shortness of breath, and palpitations after activity. Pulmonary congestion manifestations:

It is easy to suffer from recurrent respiratory infections or pneumonia, which can easily lead to heart failure and exhaustion. Therefore, the answer in the laughing shed is d.

Fetal ventricular septal defect is the best case scenario, so what is the rapid rate of fetal ventricular septal defect self-healing?

A fetus with a ventricular septal defect is a type of congenital heart disease. Membranous defects are more common among the types of ventricular septal defects. If there is a ventricular septal defect, you can regularly observe the cardiac ultrasound to determine whether the defect is gradually healing.

If healing occurs before school age, no special treatment is required. In general, the self-healing rate of ventricular septal defect can reach more than 50%. Of course, if there is no healing, it is still necessary to perform cardiac interventional closure surgery or cardiac surgery in time.

In fact, there is a high probability that the ventricular septal defect will close spontaneously. About 20 to 50% of perimembranous or trabecular defects may heal within 5 years of age, but most cases occur within 1 year of age. If aortic prolapse occurs in the early stages and the aortic valve is regurgitated, surgery should be performed as soon as possible**.

After birth, avoiding respiratory infections, choking on milk, and crying can greatly increase the likelihood of natural closure.

Summary. Hello, if the ultrasound reveals a fetal ventricular septal defect, it should be further determined whether the fetus is a complex congenital heart disease or a simple ventricular septal defect in order to determine the next step** plan. For fetuses with complex congenital heart disease, tests such as amniocentesis are needed to determine whether there is a chromosomal problem in the fetus.

If the fetus is chromosomally normal, the pregnant woman should consult a pediatric cardiac surgeon to find out what the protocol is after the birth of the fetus and how it works. For fetuses with simple ventricular septal defects, that is, without other cardiac malformations, such as right heart double outlets, transposition of large vessels, etc., observation can continue during pregnancy.

Hello, if a fetal ventricular septal defect is found on a canopy ultrasound, it should be further determined whether the fetus is a complex congenital heart disease or a simple ventricular septal defect in order to determine the next step** plan. For fetuses with complex congenital heart disease, tests such as amniocentesis are needed to determine whether there is a chromosomal problem in the fetus. If the fetus is chromosomally normal, the pregnant woman should consult a pediatric cardiac surgeon to find out what the protocol is after the birth of the fetus and how it works.

For fetuses with simple ventricular septal defects, i.e., if there is no stall, it is combined with other cardiac malformations, such as right heart double outlets, transposition of large vessels, etc., and can continue to be observed during pregnancy.

Hello, if you find a ventricular septal defect in the third trimester of pregnancy, you must pay attention to regular follow-up visits and reexaminations to see the specific changes in the fetus. If it is normal to keep the hole straight, then Na Trembling Hu will be eliminated according to normal delivery.

Hello, fetal ventricular septal defect is first recommended for pregnant women to do further examination, if the symptoms of the deficiency are mild, it can usually heal on its own. If the symptoms of fetal defect are more severe, the deficiency can be performed by surgery**. It is recommended that pregnant women relax their mood and pay more attention to rest.

Summary. It is generally accepted that ventricular septal defects of 3 mm or less are not necessary. If the defect is greater than 3mm, it can be achieved by surgery or intervention.

Hello dear, glad to answer for you. For fetal ventricular septal defects, chromosomal tests are recommended to pay attention to whether the fetus's chromosomes are normal. If a fetal ventricular septal defect is found in the second trimester of pregnancy, further fetal ultrasonography is recommended to measure the extent of the ventricular septal defect.

If it is a small defect, the impact on the fetus is generally small, and it is recommended to do amniocentesis and pay attention to the chromosomes.

If the chromosomes are normal, Zaoju recommends that Huilian recheck the fetal heart color ultrasound every month, and pay attention to the degree of change in the ventricular septal defect. After birth, the baby will need to be consulted in a cardiac surgeon, which may need surgery to correct it. In addition, it is necessary to do a detailed fetal three-dimensional color ultrasound to pay attention to whether other organs of the fetus are combined with malformations at the same time.

For particularly severe ventricular septal defects, if accompanied by obvious chromosomal abnormalities, it is recommended to terminate the pregnancy and give up the fetus, because such fetuses are difficult to correct after birth, and the prognosis is not good.

Are all official?

This is a further examination that is required, and you can talk to your doctor to see what he needs to do.

At present, it is generally believed that the size of the ventricular septal defect is 3mm or less and there is no need to talk about it. If the defect is greater than 3mm, it can be achieved by surgery or intervention.

So can this fetus still have a problem with future growth?

Dear, this needs to be further done fetal heart color ultrasound, to measure the degree of ventricular septal defect in the balance wheel stockings. If it is a small defect, it generally has no effect on the fetus.

If the defect is small, do I need surgery after giving birth? It will heal automatically.

If it is a small defect, it will heal automatically, and there is no need for **.
