4. ASD
• An atrialseptal defect (ASD) is a hole in the wall between the two upper
chambers of your heart.
• The condition is present from birth (congenital).
• Smaller atrialseptal defects may close on their own during infancy or early
childhood.
• Large and long-standing atrialseptal defects can damage your heart and
lungs. An adult who has had an undetected atrialseptal defect for decades
may have a shortened life span from heart failure or high blood pressure in
the lungs. Intervention is usually necessary to repair atrialseptal defects to
prevent complications.
5. Causes of Atrial Septal Defect (ASD)
• Doctors know that heart defects present at birth (congenital) arise from
errors early in the heart development, but there is often no clear cause.
Genetics and environmental factors may play a role.
• An atrialseptal defect allows freshly oxygenated blood to flow from the left
upper chamber of the heart (left atrium) into the right upper chamber of the
heart (right atrium). There it mixes with deoxygenated blood and is
pumped to the lungs, even though it is already refreshed with oxygen.
• If the atrialseptal defect is large, this extra blood volume can overfill the
lungs and overwork the heart. If not treated, the right side of the heart
eventually enlarges and weakens. In some cases, the blood pressure in your
lungs increases as well, leading to pulmonary hypertension.
6. Symptoms of Atrial Septal Defect (ASD)
• Many babies born with atrialseptal defects do not have
signs or symptoms. In adults, signs or symptoms may
not develop until age 30 or later.
• Your doctor may first uncover an atrialseptal defect
during a regular checkup while listening to your heart
using a stethoscope. Hearing a heart murmur may signal
a hole in your heart.
• Atrialseptal defects are often found when an ultrasound
exam of the heart (echocardiogram) is done for another
reason.
• Signs and symptoms of atrialseptal defects develop once
damage occurs to the heart and lungs. Infants with larger
atrialseptal defects may have poor appetites and not
grow as they should. Adults and infants may have signs
of heart failure or arrhythmias.

10. Percutaneous ASD closure
• Percutaneous closure of an ASD is
indicated for the closure of secundum
ASDs with a sufficient rim of tissue
around the septal defect so that the
closure device does not impinge upon
the SVC, IVC, or the tricuspid or
mitral valvs.
• The Amplatzer Septal Occluder (ASO)
is commonly used to close ASDs. The
ASO consists of two self-expandable
round discs connected to each other
with a 4 mm waist, made up of 0.004–
0.005´´ Nitinol wire mesh filled with
Dacron fabric.
• Percutaneous closure is the method of
choice in most centres.
