Atrial septal defects of 6 mm in newborns are less likely to heal on their own, but no specific data are available. Atrial septal defects are relatively common in newborns. In general, atrial septal defects less than 5 mm may gradually improve on their own with age as Boab grows and develops. If the atrial septal defect is larger, up to 6 millimeters, it is less likely to heal on its own, but there is no definitive data. Surgery needs to be considered if the atrial septal defect is still present above the age of three years, or if there is a primary foramen ovale pattern, or if it is associated with complications such as heart failure or pulmonary hypertension. It is important to note that the presence of atrial septal defects requires regular review of the cardiac ultrasound in three to six months to follow up the closure of the atrial septal defects, and if necessary, interventional or surgical treatment can be carried out under the guidance of a specialized physician in order to cure the disease.
