What is atrial septal defect in newborn baby?

An atrial septal defect is a birth defect of the heart in which there is a hole in the wall (septum) that divides the upper chambers (atria) of the heart. A hole can vary in size and may close on its own or may require surgery. An atrial septal defect is one type of congenital heart defect.

What is atrial septal defect called?

An atrial septal defect (ASD) is a hole in the septum, which is the muscular wall that separates the heart’s two upper chambers (atria). An ASD is a defect you are born with (congenital defect) that happens when the septum does not form properly. It is commonly called a “hole in the heart.”

How does atrial septal defect occur?

An atrial septal defect occurs when there is a failure to close the communication between the right and left atria. It encompasses defects involving both the true septal membrane and other defects that allow for communication between both atria.

How common is ASD in newborns?

It’s the most common form of ASD. About 8 out of every 10 babies born with ASDs have secundum defects. At least half of all secundum ASDs close on their own. However, this is less likely if the defect is large.

How long does an ASD repair take?

The repair will take about 2 hours. The healthcare provider will insert a small, flexible tube (catheter) into an artery in the groin. This tube will have a small device inside it. The healthcare provider will thread the tube through the blood vessel all the way to the atrial septum.

What is the cause of atrioventricular septal defect?

The condition occurs when there’s a hole between the heart’s chambers and problems with the valves that regulate blood flow in the heart. Sometimes called endocardial cushion defect or atrioventricular septal defect, atrioventricular canal defect is present at birth (congenital).

What is the most common type of atrial septal defect?

Secundum. This is the most common type of ASD and occurs in the middle of the wall between the atria (atrial septum).

Primum. This defect occurs in the lower part of the atrial septum and might occur with other congenital heart problems.

Sinus venosus.

Coronary sinus.

What causes congenital heart defect in infants?

Maternal factors and CHDs. Most cases of congenital heart defect have no known cause.

Family history and CHDs. About 1% of all children are born with a congenital heart defect.

Chromosome abnormalities and CHDs. Chromosomes are the structures in your cells that contain your genes.

When your child has a ventricular septal defect (VSD)?

When Your Child Has a Ventricular Septal Defect (VSD) The heart has 4 chambers. A ventricular septal defect (VSD) is a hole in the dividing wall (ventricular septum) between the 2 lower chambers (ventricles) of the heart . A VSD can occur anywhere in the ventricular septum. Left untreated, this defect can lead to certain heart problems over time.
