2024年1月23日 · An atrial septal defect (ASD) is a heart condition that you're born with. That means it's a congenital heart defect. People with an ASD have a hole between the upper heart chambers. The hole increases the amount of blood going through the lungs.

ASD is a defect in the septum between the heart's two upper chambers. The septum is a wall that separates the heart's left and right sides. What causes it? Every child is born with an opening between the upper heart chambers. It's a normal fetal opening that allows blood to detour away from the lungs before birth.

An atrial septal defect (ASD) is a congenital heart defect that involves a hole in the atrial septum. This is the muscular wall that separates the two upper chambers (atria) of the heart. Small ASDs usually don’t need treatment.

2025年1月21日 · Atrial septal defect (ASD) is one of the most common types of congenital heart defects, occurring in about 25% of children. An ASD occurs when the communication between the right and left atria fails to close. ASD encompasses defects in the true septal membrane and other abnormalities that permit communication between the atria.

2024年10月21日 · An atrial septal defect is a hole in the wall (septum) that divides the upper chambers (atria) of the heart. People with this condition should schedule routine checkups with a heart doctor to stay as healthy as possible.

2024年1月23日 · Some atrial septal defects (ASDs) are found before or soon after a child is born. But smaller ones may not be found until later in life. If an ASD is present, a healthcare professional may hear a whooshing sound called a heart murmur when listening to the heart with a device called a stethoscope.

An atrial septal defect (ASD) is a congenital heart defect, a problem with the heart’s structure that is present at birth. Put most simply, an ASD is an abnormal hole in the wall that divides the atria—the two upper chambers of the heart.

What is Atrial Septal Defect (ASD)? Atrial septal defect (ASD) is a heart defect that is present at birth (congenital). As a baby develops in the womb, a wall (septum) forms that divides the upper chamber into a left and right atrium. When this wall does not form correctly, it can result in a defect that remains after birth.
