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.
