Preliminary experiences closing secundum atrial septal defect using the modified Cardia Intrasept device.

During the past decade, transcatheter occlusion of secundum atrial septal defects (Type II ASDs) has become a widely accepted alternative to surgical closure. To date, over 6,000 patients have been treated with the Cardia Intrasept PFO occluder (Cardia Inc., Burnsville, Minnesota) for the percutaneous closure of patent foramen ovale (PFO). This is a report of the use of a modified Intrasept device to close Type II ASDs in 4 patients.
