Atrial Septal Defects (ASD)

An atrial septal defect (ASD) is an abnormal hole (defect) in the wall (septum) between the heart’s upper chambers (atria). The hole might be as small as a pencil point or as large as the entire septum. The exact causes of an ASD are not known. Many ASDs close spontaneously in the first years of life.

The GORE® CARDIOFORM Septal Occluder is a minimally invasive device intended for the closure of an ASD using cardiac catheterization. It is a permanent implant consisting of a wire frame covered with a thin ePTFE membrane.
