Atrial septal defects of 6 mm in adults do not resolve spontaneously and can usually be treated with interventional therapy or atrial septal defect repair.
Atrial septal defects are characterized by abnormal development, resorption, and fusion of the atrial septum, resulting in a residual unsealed defect between the right and left atria. The defect does not cause clinical symptoms in childhood, but in adulthood it causes weakness, palpitations, and arrhythmias. Adults with atrial septal defects of 6 mm should be treated with either interventional or atrial septal defect repair.
Interventional procedures deliver a blocker to the atrial septal defect by means of an interventional procedure to block the left-to-right shunt and achieve a therapeutic effect. If there are contraindications to interventional surgery, the surgical procedure of atrial septal defect repair can be used to treat the condition.
Adults who are found to have 6mm atrial septal defects should go to the hospital in time and receive symptomatic treatment under the doctor’s guidance to avoid delays.
