What is the cause of the small hole in the baby's heart?

Babies are a special group because they have poor resistance and immunity and weak physical fitness. Therefore, they can suffer from various diseases if they are not careful. So what is the cause of the small hole in the baby's heart? If you are not very clear about this disease, it is best to send your baby to a regular children's hospital for examination. Only in this way can your baby receive treatment as soon as possible.

Congenital heart disease is the most common heart disease in children:

1. Congenital heart disease is the most common heart disease in children, usually due to abnormal development of heart structure caused by harmful factors in early pregnancy

2. According to your situation, you are one year and two months old and have heart murmurs. You have been to Dayao County People's Hospital for treatment and were diagnosed with congenital heart disease. In this case, a cardiac ultrasound examination is required to determine the type of congenital heart disease and whether there is pulmonary hypertension;

3. If conditions permit, surgical treatment should be performed at around 3 years old. Currently, surgery for congenital heart disease is very mature and does not involve much risk.

Before birth, newborns rely on the mother's umbilical cord for blood supply. The left and right sides of the heart are connected through the oval foramen, which will close by itself within a period of time after birth, so you don't need to worry. Neonatal jaundice is also a common phenomenon and it will get better after observation and treatment in the hospital for a period of time.

This is a congenital heart disease. There are different types of congenital heart disease according to the location of the "hole". Generally, atrial septal defect and ventricular septal defect are the most common. The cause of its occurrence is still unclear. The internal factors are mainly related to genetics. The more important external factors are intrauterine infection, especially viral infections such as rubella and influenza in the early pregnancy. Drugs such as anticancer drugs and anti-epileptic drugs are also one of the reasons. Some cold medicines and antiviral drugs also have the risk of teratogenicity. Therefore, drugs should be used with caution during pregnancy, especially in the early pregnancy. Whether the child's "hole" will heal on its own depends mainly on the location and size of the hole, the shunt volume, the pulmonary artery pressure level, etc. Generally speaking, atrial septal defects smaller than 3mm will close naturally within 3 months, while atrial septal defects larger than 8mm are less likely to close naturally. Those with larger shunt volumes require surgery or interventional cardiac catheterization treatment. Ventricular septal defects may also close naturally within 5 years of age, but after 5 years of age, the possibility of natural closure is very small. Therefore, small and medium-sized defects can be followed up in the outpatient clinic until the preschool period, while large and medium-sized defects and those with a continuous increase in pulmonary artery pressure to a certain standard should be treated early. During the observation period, you should follow the doctor's instructions: pay attention to preventing respiratory infections, go to the hospital for treatment in time if you have symptoms such as a cold, and regularly check your heart with color Doppler ultrasound to understand your heart condition. If necessary, go to an authoritative pediatric heart disease hospital for treatment to avoid missing the best time for surgery.

Since babies are relatively young, they have certain problems in expression. So at this time, mom and dad play a vital role. They should always pay attention to the baby's physical changes. If you find that there is anything wrong with your baby, you must receive treatment in time. Although a small hole in the baby's heart is a relatively serious condition, it does not mean that there is no cure.
