Is atrial septal defect common in neonates

summary

Neonatal atrial septal defect (ASD) is a kind of neonatal disease, because the newborn just separated from the mother soon, their various organs are not mature, so the resistance will be much weaker than adults, let's talk about the common neonatal atrial septal defect.

Is atrial septal defect common in neonates

First: because under certain conditions, the baby's atrial septal defect has the possibility of closure. Generally speaking, some small central secundum ASD can be closed naturally, with a closure rate of about 20% ~ 39%. The mechanism of natural closure is that the atrial septum continues to develop, so it mostly occurs within 1 year old, and rarely occurs after 4 years old.

Second, the possibility of natural closure is very low when the diameter is less than 4mm, but the possibility of natural closure is very low when the diameter is more than 8mm. Atrial septal defect in infants and young children in general will not occur in the symptoms of cardiac insufficiency, there may be self closure, it does not need treatment. Even if there is no possibility of closure, there is no need to worry too much.

Third, the fundamental method to treat congenital heart disease is to correct the cardiac vascular malformation by surgical operation, so as to eliminate the pathophysiological changes caused by the malformation. For example, surgical operations often need to cut the viscera and require hypothermic anesthesia or cardiopulmonary bypass. If the ASD is too large, parents can allow the baby to have surgery after one year old.

matters needing attention

Therefore, the incidence of neonatal atrial septal defect is still very high, which also tells some expectant mothers that they must pay attention to their living habits during pregnancy, and never catch some bad habits, which will also have an impact on the future of the baby.
