ASD can be repaired non surgically or by surgery. Non-surgical treatment uses closure devices called septal occluders which are inserted using catheters from large veins of the leg. This device seals the hole over which tissue grows eventually and the device becomes a part of the heart. ASD can be repaired surgically using tissue patches. In addition to this the doctor also prescribes blood thinning medications which needs to be taken for a period of 6-12 months depending upon the recovery status of the patient
