Also known as: ASD, coronary sinus atrial septal defect
An Atrial Septal Defect is a heart condition that is present at birth due to abnormal development of the fetal heart during pregnancy. An ASD is a hole in the wall between the two upper chambers of the heart called the right and left atria.
Most of the time this heart defect occurs by chance, with no clear reason for their development.
An ASD may be discovered during your child's physical exam, while a pediatrician is listening to his/her heart. If a murmur (an abnormal heart sound) is detected, your child will be referred to a pediatric cardiologist for a diagnosis. Tests that a pediatric cardiologist may recommend include:
If the ASD is small, it may not cause problems and close up on its own as your child grows. In this case, your doctor may recommend monitoring your child's condition. Some ASDs are treated with cardiac catheterization, while other children need surgical repair. This condition is also treated with a Transcatheter Atrial Septal Defect Device Closure.

Tricuspid atresia is a problem with the development of the right side of the heart where this valve has not developed, with a smaller than normal lower right pumping chamber.
When the heartbeat is interrupted by unusual sounds such as blowing, whooshing or rasping, it’s called a heart murmur.
Transcatheter atrial septal defect device closure is a minimally invasive solution for ASD that is as effective as open heart surgery.
Your child may need atrial septal defect (ASD) repair if they have a hole between the two upper chambers of their heart. During ASD surgery, the physician sews a patch into the heart to close the hole.
