The Ampltazer septal occluder (ASO) is the most commonly used device as it allows closure of large cavities, is easy to implant, and boasts high success rates. As an instrument, the ASO consists of two self-expandable round discs connected to each other with a 4-mm waist, made up of 0.004–0.005´´ nitinol wire mesh filled with Dacron fabric. Implantation of the device is relatively easy. The prevalence of residual defect is low. The disadvantages are a thick profile of the device and concern related to a large amount of nitinol (a nickel-titanium compound) in the device and consequent potential for nickel toxicity. | The Ampltazer septal occluder (ASO) is the most commonly used device as it allows closure of large cavities, is easy to implant, and boasts high success rates.

Percutaneous closure
Percutaneous transcatheter closure is current only indicated for the closure of ostium secundum atrial septal defects. It should not be used in patients with sinus venosus, primum or patent foramen ovale atrial septal defects. In patients with a secundum defect, there must be a sufficient rim of tissue around the septal defect.
The Food and Drug Administration has authorized the following percutaenous transcatheters for usage:[1]
- Amplatzer septal occluder
- CardioSEAL
- HELEX septal occluder
- Sideris patch
