Surgical therapy
Surgical closure of an ASD involves opening up at least one atrium and closing the defect.
General techniques for engaging in surgical closure include:
- Median sternotomy
- Right anterolateral submammary sub pectoral (most preferred in females)
Other minimally invasive approaches include:
- Upper hemisteronomy
- Right parasternal
- Right submammary bikini line (for females)
- Limited median sternotomy (for males)
- Transxiphoid sternotomy (for children or young adults)
It is advised that an anterolateral approach only be used in adults as it may damage prepubescent girls during development of breast tissue.
Surgical approaches for small atrial septal defects
In the case of a small atrial septal defect, a surgeon can perform a direct arterial and double venuous cannulation via a median sternotomy incision. Most small atrial septal defects can be repaired while the heart is under an a cardioplegia solution induced arrest utilizing a prolene suture.
Surgical approaches for larger atrial septal defects
In larger atrial septal defects, the atrium of the aorta can become distorted during closure. A superior defect, when closed directly, may result in an distortion of the aortic anulus. Instead, a synthetic patch made of Dacron or PTFE can be used to close the aorta. If performed inappropriately, this procedure runs the risk of an air emboli.
