Is fetal atrial septal defect normal?

summary

Fetal atrial septal defect (ASD) is generally congenital, but neonatal ASD is not very common. Nowadays, with the rapid development of society, people's living standards and quality awareness have been improved, and medical conditions and health conditions have been greatly improved. Generally speaking, the children born by healthy parties are very healthy newborns, Pregnant women with rubella or virus infection in the third month of pregnancy, and the use of certain drugs can lead to fetal hypoplasia, resulting in atrial septal defect. The circulation resistance is high and the blood flow is small, so the blood returning to the right atrium must be able to enter the left atrium through the atrial septum to adapt to the special circulation physiological requirements of the fetus. Let's take a look at the following.

Is fetal atrial septal defect normal?

First, atrial septal defect (ASD) is a common congenital heart malformation in medicine, which is caused by the abnormality of the original atrial septum in the process of embryonic development, resulting in the left and right atrial pores. At the fourth week of embryonic development, the atrium was divided into left and right atrium by the original atrial septum which originated from the posterior superior wall and grew towards the endocardial cushion. With the growth of endocardial cushion, the atrium gradually contacted and fused with the lower edge of the original atrial septum, and finally closed the residual space between them.

Second: most of the children are thin and weak, and often show a slight protrusion of the left anterior chest wall, increased heart beat, and can touch the right ventricular lifting feeling. If the secundum atrial septal defect is less than 5mm, it can be observed and treated actively.

Third: most of the children with secundum atrial septal defect have no symptoms except for respiratory tract infection such as cold, and their activities are not limited. They usually show shortness of breath, palpitations, fatigue and so on in their youth. Atrial fibrillation, atrial flutter and other arrhythmias and congestive heart failure often appear, which is also an important cause of death.

matters needing attention

The natural course of the patients with atrial septal defect (ASD) is related to the type of ASD, the size of shunt and whether there are other types of cardiac malformations. Most of the patients can grow to adulthood, but their life span is shortened, and they die of congestive heart failure.
