Device Closure

Device Closure

An Atrial Septal Defect (ASD) is an opening or hole in the wall that separates the two upper chambers of the heart. This wall is called the atrial septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side. This causes extra work for the right side of the heart, since more blood than necessary is flowing through the right ventricle to the lungs.

If the ASD is small enough, it can be closed with a special device. The procedure is done in the heart catheterization lab.

Types of Atrial Septal Defects :

Atrial Septal Defects are classified by where they occur and their size.

  • A secundum ASD is a hole in the middle of the atrial septum, which lets blood flow from the left chamber to the right chamber, or from the right chamber to the left chamber, depending on pressures in the atria.
  • A patent foramen ovale (PFO) is a “flap” that is present when the atrial septum does not close properly at birth. A PFO allows blood to flow from the right atrium to the left atrium. This type of defect generally only permits blood flow when there is more pressure inside the chest, such as straining during a bowel movement, coughing or sneezing.
