Atrial septal defect (ASD) and patent foramen ovale (PFO) are common clinical congenital heart defects. As an effective method for the treatment of ASD and PFO, transcatheter closure with occluders presents many advantages, including safety, ease of operation, minimal invasiveness, and reduced complications. This contribution reviews the various types of occluders currently used in clinical applications and under development, including non degradable occluders, partially degradable occluders, and totally degradable occluders. A number of case studies are described in detail. Comparison is made on the treatment outcomes using different occulders. Future development of transcatheter closure is discussed, in particular the use of totally degradable occluders. © 2016 Wiley Periodicals, Inc.
