  • An atrial septal defect is a hole between the two atriums of the heart. Normally this hole is present at birth but closes within a few days of life. Failure of this hole to close is called an atrial septal defect, and usually is asymptomatic (no obvious symptoms are present). Created by Leslie Samuel.

    I had atrial septal defect as a baby and they told my mom they would operate on me when i was 3. They said the hole was pretty big for a baby's heart but thankfully it closed and the doctor said it was a miracle. I am now 14 and have decided to be a pediatric cardiologist. Thanks to all the doctors out there😃

      Ashley Garcia Do you have any limitations or did the surgery fix everything? Also did they go in through your leg because if I did get it they told my mom that's how they would do it

    I'm just coming across this studying for an exam in advanced pathophysiology as part of my studies to become a Family Nurse Practitioner. Your wonderful illustration and explanation helped me understand that the "split" sound is coming from the aortic valve closing before the pulmonic valve ( due to excess volume of blood). Thank you for this!

    My asd wasn't found until in my 40's. After closure I developed paroxysmal atrial fibrillation. Now 4 years later, I was just diagnosed with congestive heart failure..I have left ventricle stiffness. I had echos done throughout the years and no doctor caught it..

    Ostium secundum defect is created because of excessive muscular resorption or excessive programmed cell death (apoptosis) of the septum primum essentially leaving a bigger hole ( ostium secundum) that overlaps the septum secundum. Systemic vascular resistance is higher during birth which in normal circumstances the left atrial pressure increases and pushes septum primum and septum secundum together for an anatomical closure that eventually will lead to fusion of septum into one atrial septum. But because righ side of heart has lower pressure the blood leaks back from the left atrium to right atrium converting it from a physiological normal right to left shunt through the valves to left to right shunt through a hole. This eventually leads to a increase in blood volume as less blood is getting out of the heart, therefore it increases preload and end diastolic volume. This leads to an increase in presure and contraction force for the left ventricle to push blood out of heart. This can go into two directions the left ventricle hypertrofies to push out more blood or it dilates to the point of no return ( left heart failure). If left heart failure occurs the pulmonary trunk will begin to do excessive work till the point where pulmonary hypertension develops because of excessive blood volume and right heart hypetrophy or dilation begins to occur because pulmonary vascular resistance is higher than systemic vascular resistance leading in the end to a righ to left shunt later in life ( Eisenmenger syndrome).

    I am 24 and I got diagnosed with ASD recently after 2d Echo, I have never had any symptoms as such , sometimes a breathlessness only if I perform any strenuous activity like fast running, trekking, etc. Dr. Said the whole is big comparatively and abnormal heart rates are observed now will be undergoing a surgery soon. What is the success rate and can i lead a normal, healthy life afterwards??

    it gradually increased
    took ecg 4 different hospitals all told that didn't get clear graph
    but yesterday when I consulted doctor
    he detailEd took 2d echo
    he was not sure but maybe chance having hole in heart
    it is not visible in 2d echo
    he advised to take tee to R/O ASD
    (hence it is not clearly visible in 2d echo . how may chance of hole size??)

I only found out in april because I had suspected meningitis and when I was in hospital they heard a murmur when they were listening to m chest. I have a ASD that is over two chambers. I'm waiting now open heart surgery at st Thomas's hospital on London for a closure.

I didn't have these symtoms all my life though just the recent months and that's why I got it checked out and they found my ASD. I will have it closed by catheter closure (Amplatzer device) in a month :) I hope your surgery goes well for you! It almost always does wether it's with device or by open heart surgery.

    Good for general population, but not complete enough for medical students. It's missing the explanation of how pulmonary hypertension occurs and how the left-> right blood flow changes to right->left after some time, which in turn opens the possibility for a paradoxical thromboembolism. You also need to include the embryology part and explain how the atrial septum is formed in the first place and how the foramen ovale is supposed to look and function, and how it functions in ASD, differences in pressures between right and left atrium, how they change as the defects progress, etc. That is all important to really understand what's going on.

      It says right in the name of the video that this is specifically for NCLEX prep. This is exactly what nursing students need to know about this heart defect. Of course Medical students would need to get more in depth, but that is not who this video is for.

    You are one the greatest instructors I am able to fully understand completely. Thank you for the vids, and hope to see more!

    I was looking for the Dr. Najeeb lecture on CHD's (which is exceptionally good) and I couldn't find it so I watched this. I think you first need to cover the development aspect, at least the interatrial septum. You don't explain what the septum primum and secundum are but tell that if the defect is in middle it's a secundum defect! That's atrocious!
