How often does the corrective surgery for asd fail?

Very rarely. ASD surgery is usually very successful. There are some types of ASD that are more challenging, and there is a higher risk of having a small residual defect. While not a complete closure, small residual defects are not considered failures.
Device closure. Is the standard now. It has a very high success rate (in our series >95%) the remainder are referred to surgery with a 100% success rate.
