Atrial Septal Defect. Hole in the heart...a residual communication between the two upper heart chambers. In most hearts, the flow is from the red side towards the blue (or right) side of the heart. This causes overload of the right heart, but is usually well tolerated. There are several varieties of ASDs depending on the location and associated abnormalities. Repair is by direct suture closure or patch closure.

Atrial septal defect. Normally there is a wall or "septum" between the right and left atrium, the upper, low-pressure chambers of the heart. When there is a hole in that wall allowing blood to flow both directions it is called an atrial septal defect or"ASD".

Atrial Septal Defect. a hole in the wall between the atria.

See Atrial septal defect

Atrial septal defect. An abnormal opening or hole in the septum between the right and left atria. Normally, the flow of blood will be from left to right (left to right shunt). Blood flow from right to left (right to left shunt) will be present only if there are other complicating conditions leading to a higher pressure on the right side, such as pulmonary stenosis or tricuspid atresia, which impede or prevent the normal flow of blood from the right ventricle to the lungs.
