What does the atrial septum do?

The atrial septal defect provides a communication between the right and the left atria. This allows blood to flow across the opening from the left atrium to the right atrium causing an increased volume of blood to be delivered to the right side of the heart, and subsequently to the lungs.

What is atrial ventricular septum?

Atrial and ventricular septal defects are holes in the walls (septa) that separate the heart into the left and right sides. Holes can be present in the walls of the heart between the upper heart chambers or between the lower heart chambers. Many defects are small, cause no symptoms, and close without treatment.

What is the most common cause of atrial septal defect?

Atrial septal defect occurs in 5 to 10 percent of all babies with congenital heart disease. The most common form of ASD is an ostium secundum, an opening in the middle of the atrial septum. For unknown reasons, girls have atrial septal defects twice as often as boys.

What is heart septum?

Septum, heart: The septum of the heart is the dividing wall between the right and left sides of the heart.

What happens if you have a hole in your heart septum?

The hole increases the amount of blood that flows through the lungs. A large, long-standing atrial septal defect can damage your heart and lungs. Surgery or device closure might be necessary to repair atrial septal defects to prevent complications.

Why is the septum in the heart important?

In this process, septum plays an important role, it separates the atria and the ventricle in such a way that it kind of forms a barrier between the chambers of the heart which prevents the mixing of oxygenated (oxygen-rich) and deoxygenated blood (oxygen-poor).

Does atrial septal defect go away?

Small atrial septum defects may close on their own. Atrial septum defects that are large or cause symptoms can be repaired. Most children who have had an atrial septal defect repair will live healthy lives.
