Atrial septal defect | Circulatory System and Disease | NCLEX-RN | Khan Academy

[@kaylaray151]

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😃

[@gulabnewa7392]

thats great and bad at the same time but thank GOD for helping u get better.😷😷😷😷😷😷👼👼👼👼👼👼👼💪💪💪🙏🙏🙏🙏🙏 and stay strong

+Gulab Newa Thanks

[@ashleygarcia3631]

Had the same thing, had to get the surgery when I was 3. The hole was also very big for me at the time as a three year old. I'm 16 now :)

[@kaylaray151]

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

[@Mut1late]

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!

[@jovanazlatkovic_]

This is so good! U explain it so good it that this video should be in medical classes for sure!

[@laurayiselrodriguez4254]

These videos never cease to amaze me. I speak for many when I say that I am grateful and forever mind blown at the ease and exemplary way in which you guys break these difficult "textbook" concepts down. THANK YOU times a million!!!

[@coli503]

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

[@lindsycoon3233]

"and you know, they go to take a poop, and when they take a poop of course there is a lot of pressure...." Thanks for keeping things interesting.

[@vividdawn8793]

Hahaha! At this part I thought "so glad I didn't have my stroke on the potty!" My stroke was when I was sleeping, from atrial fibrillation, and probably went through my VSD instead.

[@CoolKeysAndcrEamCAKE]

I was paying attention to what's he's saying then when he said "poop", I just can't help but laugh. 😂

[@liyichen9317]

TAKING A POOP ALSO HAS A POTENTIAL FOR DEVELOPING SUBARACHNOID HEMORRHAGE LOL

[@biphkreimier8210]

Thanks for this!! I had a stroke 6 years ago and now I finally know how it happened. My mom drank when I was in utero, had a hole that went undetected until my stroke

[@Ashmooni]

I had a stroke and my mom wasn’t drinking. PFO happens in 1 in 4

[@excalibur9768]

Kudos on mentioning paradoxical embolism but it should also be noted that a significant ASD will cause right heart dilation from the volume overload, pulmonary hypertension, and eventually right heart failure.

[@MEDSimplified]

Super video.. I admire ur work

[@karenpanzner2786]

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..

[@irenec1840]

This educator was fantastic and its evident he loves what he does. Thank you

[@khdr4165]

Wish you were living near by hahah so that i could ask you and understand everything about medicine as it should be💔 Thanks alot sir.

[@derbigpr500]

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.

[@RawhideProductions1]

What are you doing watching youtube vids when youre paying six figures for school and $200 for textbooks? KZbin is for cat videos and old movie clips from the 80s.

[@Lammchop14]

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.

[@chucknorrislife]

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).

[@bellguts2766]

Thanks for explaining this. I had a stroke at age 55 after veins being operated on in my leg. It was discovered I had ASD and it was surgically repaired.

[@salamibrahim3018]

Hi i am 55 years old and I did make this operation 5 years ago and i feeling good So my question it's if is dangerous to take viagra Thanks

Very well done and super simple. Thanks ! Keep it up!

[@MrColdbreeze16]

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!

[@Denisey411]

Please make a video on Atrioventricular Canal Defect :)

[@Tennis-3582]

Wow really very very informative thanks is not enough to thank you !!

[@ronymangalath3297]

This video is very Informative!! I have two Q's: After doing ASD closure medical procedure, would ASD reoccur sometime in the future? can the person lead a normal life?

[@ttmleonard]

After having one the patient is completely fixed with one large scar and 4 smaller ones, the patient probably has a check up once every 4 years but apart from that the patient can lead a perfectly normal life.

[@nyamurungibtumusiime4562]

Perfect...excellent....great👌👌👌👌👌👏

[@bimmyakin]

It can also lead to infective endocarditis due 4o organisms forming colonies on the abnormal shunt

[@goncalocorreiapinto6205]

According to Harrison's 18th edition, the risk of infectious endocarditis in ASD is very low except if the defect is accompanied by AV valve insufficiency or in the postoperative period following the ASD repair.

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??

[@shreyanatu607]

[@lolittalangdon2434]

merci. 💞

[@hatemkaabi371]

why is it the second sound get split i mean why does the pulmonary valve get close late? is it because the high pressure became in the right side of the heart??? thanks for the amazing video n ur nice explaining

[@ssglengele1]

I have a quick question my daughter is 3 yo and has a ASD with right sided hypertrophy. What level of risk is there for damage to the pulmonary system from the larger volume of blood being introduced to the system and increased pressure over time.

I'm 19 years I'm getting little heart pain like something from 14 years 8 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??)

[@danladking9788]

Had a Toe for PFO closure and told my atrial septum has a very aneurysmal appearance. An ultrasound of my heart report my atrial septum is thin, mobile and aneurysmal. Guessing in layman’s terms this means I have atrial septum defect lol. If anyone can confirm that, much appreciated. Thanks. Previously had a cryptogenic stroke 9 months ago at age 36 with a PFO that’s just been closed.

[@cynthiacoxe]

I have this an going to have surgery Wednesday. I am so scared. I have had a stroke and a heart attack. I have had chest discomfort for years . I was 23 when they found this. Now I am 37 with 2 kids.

[@neatrom2082]

Did you done the surgery?

[@tridibdebpabel6782]

When did you do surgery??

[@wmd40]

ASD might be asymptomatic but to therefore say it's not a big deal is just ridiculous. plus surely there are symptoms but most with it are found as babies so the info on symptomatic adult patients is just not there

[@sophiethompson1487]

I currently have this and I'm 21.

[@Ann-pn8xr]

What are your symptoms?

[@sophiethompson1487]

Hello, normally I feel a sharp pain in my chest but some days I become breathless, dizzy and lose consciousness. However other days I'm completly fine. 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.

[@LadyLoin]

Sounds like me! I also have a pressure on my chest, heart palpalations and skipped beats sometimes. Just feeling awful in general :/ I'm 20 years old so we are about the same age. 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.

[@mackenzieabril4749]

Sophie Thompson I had this too. I had to get surgery when I was 4
