Atrial septal defect is a congenital heart defect where blood flows between the upper chambers of the heart, the atria, because of a hole in the interatrial septum. It is usually asymptomatic in children but can cause difficulties breathing, respiratory infections, palpitations, and shortness of breath with activity. While small defects may close on their own, larger defects require cardiac evaluation and treatment to prevent issues like strokes or lung illnesses.

2. WHAT IS IT ???
Atrial septal defect (ASD) is a congenital heart defect in which
blood flows between the atria (upper chambers) of the heart.
Normally, the atria are separated by a dividing wall, the interatrial
septum.
Congenital heart defect (CHD), also known as a
congenital heart anomaly or congenital heart
disease, is a problem in the structure of the heart.
• The ASD is an illness that affects kids.
• It is found in the atria (heart).
• As you know, the “wall” that separes the atrium is called septum.

4. SYMPTOMS
Symptoms that do occur may begin at
any time after birth through childhood.
They can include:
1.Difficulty breathing (dyspnea)
2.Frequent respiratory infections in children
3.Feeling the heart beat palpitations in adults
4.Shortness of breath with activity

5. DEFECTS:
• Blood from both atria mixes
• It can produce other heart illnesses such as
stroke or lung illnesses.

7. SOLUTIONS
• If the hole is small, it can close on its own.
• If it is big, you should go to the cardiology
pediatrician.

8. CURIOSITIES:
• It is more common in girls than in boys.
• If you have this illness your heart produces a
murmur.
• In adults the hole is 6 mm
• In kids is 4 mm
• 1 of 1000 babies are born with ASD
