Treatment depends on the size of the hole, the types and severity of symptoms and the presence or absence of other conditions. Small holes may not cause any symptoms and may not need treatment. For larger defects causing symptoms the aim is to manage symptoms and prevent complications. No medications can repair the hole, but certain drugs can help to prevent clots and keep the heartbeat regular.
If the defect needs to be repaired, a catheter procedure may be used to plug the hole. Open heart surgery may be needed for very large defects.
