Can fetal atrial septal aneurysm heal itself?

Fetal atrial septal aneurysm may self-heal.

Fetal atrial septal aneurysm is a congenital weakness of the fetal atrial septum, which causes the atrial septum to bulge to the low pressure side under the action of cardiac load factors. If this occurs in the second trimester of pregnancy, as the fetal heart continues to grow and develop, the atrial septum can be further strengthened, the pressure capacity increases, and the bulge gradually shrinks, so the fetal atrial septal aneurysm may self-heal.

Pregnant women should regularly check and pay close attention to the fetal condition. If there is an atrial septal aneurysm, it can be detected in time for subsequent treatment.
