Overview
The Amplatzer septal occluder (ASO) is currently the most widely used device because it is easy to implant and has high success rates. It first came to be used for human subjects in 1995. However, the device is still not approved for usage in percutaneous closure of primum, sinus venosus and coronary sinus type of atrial septal defects.
Type of occluders
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 Ampltazer septal occluder 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. The prevalence of residual defect is low. The Food and Drug Administration has authorized the following percutaenous transcatheters for usage:[1].
- Amplatzer septal occluder
- CardioSEAL
- HELEX septal occluder
- Sideris patch
