If the diameter of the atrial septal defect is less than 5mm, no special treatment is needed; if the diameter is more than 5mm, surgery and minimally invasive interventional occlusion can be used.
Atrial septal defects are relatively small, and if the diameter is less than 5mm, they may grow back on their own, so they generally do not require special treatment. However, regular ultrasound examinations are needed to assess the right heart load, and if symptoms worsen, timely surgical intervention is needed.
Atrial septal defects that are relatively large, more than 5mm, are usually treated with traditional surgical procedures, which require an incision to repair the atrial septal defect. Alternatively, minimally invasive interventions can be used, which do not require an incision and deliver an occluder into the blood vessel to achieve a therapeutic effect.
Atrial septal defects may cause symptoms such as cyanosis, panic and shortness of breath.
