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

An ventricular septal defect is a hole between the two ventricles 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 a ventricular septal defect, and usually is asymptomatic (no obvious symptoms are present). Created by Leslie Samuel.

I had a patient with this disorder and this really clears up the understanding of the pathophysiology. Thanks a bunch!

[@jess1910]

i know this was posted over a year ago but thank you! it helped me understand cardiac disorders so much better !

[@redfairy100]

The L to R shunt results when the pulmonary resistance is low. However, increased amounts of blood flowing into the R ventricle are pumped to the pulmonary circulation, eventually causing an increase in pulmonary resistance, which then leads to increased pulmonary vascular resistance, causing pulmonary HTN and R ventricular hypertrophy. The effect is a R to L shunting of blood across the VSD. This can lead HF, pulmonary HTN, cyanosis, and the risk for development of aortic valve regurgitation and potential endocarditis. Is this the case if the hole in the septum is not repaired or doesn't heal spontaneously? I'm a little confused (though I love your presentation! It's very helpful and gives an excellent visual) because I'm currently studying this for nursing school and our pediatrics text book makes it sound a bit more complicated.Thanks.

[@kittkatt521]

Hello and Happy New Year of 2015 this will be the 59th anniversary of my ground breaking open heart surgery for VSD. I was 15 months old and was only given a 50-50 chance of survival and I will be 60 in May!

[@ryanmiddendorf9857]

I know this is a (very) old comment, but why did you need surgery? I had this and the doctor shrugged it off like it was no problem. I actually still have it, and it still isn't a problem. (I actually have 3 defects in my heart currently, but none of them are a problem.)

[@shoaiburrehman2810]

thanks Katie for sharing your personal experience for others patients.

[@eddiehoxha1301]

I wish you many more happy years 🎉❣️

[@angieschneider2761]

I FINALLY get how the left-to-right shunting of cardiac defects work! Thank you so much!!!

[@conversationswiththeuniver2521]

His teaching style is amazing. He makes me wanna study more!

[@cindyr1980]

I read this section in my nursing book over and over, but it wasn't until this video that it finally made sense! Thank you SO much!

[@carissawilkins3881]

"Interactive biology" guy + Khan Academy = PRICELESS learning opportunities. I am a very visual learner and these videos help so much with tough heart flow concepts that I must master in medical school!

[@jdel617]

currently a PA student in pathophysiology- this is so helpful!

[@sameenkarim8899]

You are amazing - thank you so much! These are so helpful for studying for exams!! So much content and these videos make it soooooo much easier to understand! Thank you!!

[@KayRenae409]

Soooo helpful! I literally survive PA school by watching these :) Thank you for the wonderful videos!

[@maryama.2835]

Amazing explanation, My Paediatrics exam is next week, helped me a lot! Thank you so much!! Dankeschön!!!

[@taniasantiagoleon1986]

WOW THANK YOU SO MUCH YOU ARE GREAT EXPLAINING THE DEFECT i HOPE YOU HAVE MORE VIDEOS

[@mrd2689a]

Thank you!

[@nadyaamalia4101]

thank you so much, it's very helpful!!!!!!

[@Katkiwi25]

You are incredible!!

[@AS-uy2ud]

thanks for this awesome explanation!

[@user-fe1up8rj4t]

Thank you so much!

[@caterscarrots3407]

I once saw a site full of CHD diagrams(congenital heart defects) and on that site, I saw a diagram of Single Ventricle Syndrome, basically a VSD, but so extreme that there’s either no interventricular septum or the little bit that’s there doesn’t separate the 2 ventricles.

[@sophielmd1615]

Thank you for this great explanation! Very helpful 👍

[@leratomathilda4205]

this is so helpfully thank u very much

[@johannesvanhoek9080]

You made it easy to understand, thank you sir!

[@noemirios7637]

what a great explanation thank you

[@ChrisHeightsTV]

Thank you! 🔥🙏

[@rovenapjetri1103]

so helpful video , thank you

[@suri7502]

love the explanation !

[@davidmayew955]

In 1964, I was 3 1/2 yrs old. I had open heart surgery for this defect and have a deformed mitral valve. today I am 55 yrs old. My surgery was in Chicago IL.

[@courtneybrad]

Your testimony is very encouraging to me be it that my son has a Partial AV Canal which is a mix of the two videos he did here. Although my son's defect is a bit more severe or unique (as the doctors like to say) than just a regular Partial AV, your testimony gives me hope. His condition is similar to a Complete AV canal, but isnt a complete AV canal. Its when a hole is present in the septum between the ventricles(this video) and a hole also in Septum between the left and right atrial. Thus, atrioventricular canal. Atrio-ventricular canal. The gap or hole between my sons Ventricle is somewhat formed, but not fully formed. The doctors are saying the problem wont be the gaps or holes, those are easy to fix...the hard part will be the leaky valves my son has. These are very fragile and be it he is only just over 2 weeks old they need him to grow a lot in order to perform the surgery with the highest outcome of success. Just wanted to say thank you for your story you shared here, even though my son's case is a bit different than yours, it brings me comfort to hear yours. So, I thank you.

[@ahmedalkhazraji9477]

Thank you dr for this video hope you to make more ))

[@metebasiri8120]

Amaaaaaaaaaaaaazing explanation in an easy way 😍❤️ , Thanks a lot

[@hiwotworkneh5101]

Does the condition progresses if not treated with surgery? what if the shunt is bidirectional can it still be corrected with surgery?

[@abdulwahabkhan977]

Sir dara dara manana der kha lecture wo... May you live long

[@LolaDVG]

I love this videos

[@MultiMusik4]

This is so good!

[@hlophempendulo5492]

Thank you so much

[@matthewravi5782]

why it cannot be right to left shunt by any chance, since the hole is there? Is it due to the force of the venous deoxygenated blood that is much less than the force of the arterial oxygenated blood?

[@lolittalangdon2434]

merci.💞

[@henajawaid4595]

GREAT

[@Dr_Okonji]

Very good video

[@nehashrestha833]

can u explain the phisiology of murmur of congenital heart disease please??

[@dinavimadrazo7041]

is this risk condition? i listened my baby's heart beat and i hear like this..but his not having problem in breathing..he breath normally..

[@scorpiojest6217]

is it possible a 36 y,o with VSD can be operated? is the prognosis good if your already old?

[@benjamincarvalho257]

I'd imagine they can still close it through cardiac catheter surgery, bring it up with your cardiologist!

[@MartinIgnacioLapidus]

Sir, these videos are amazing. I am teaching physiology in the UBA (University of Buenos Aires) and I really would like to make something like this. Would you please tell me what application or software do you use to create such didactical videos?

[@Pauliuris]

+Martin Ignacio Lapidus Me parece que es con una tableta especial, MEDCRAM videos (también aquí en KZbin) usa una técnica similar.

[@cemcemzer0]

i am a medicine student, this videos are really helpfull to me. thank you.

[@DFive7eHven]

Why can't you be my instructor! Your method of teaching works for me! I guess this would have to do

[@sage8092]

I have VSD!! I still have it. And when I hear normal heart beats its different. Mine is abt 0.5 cm

[@Emma_French20]

m a g i c same I hate having it and also I have fasd and ADHD and learning difficulties

[@matthewbates9629]

So do I

[@drrajeshsharma4672]

nice

[@user-ms3cv8ot4l]

احبك موت

[@JohnDoe-rv4kp]

And then you also have Outlet VSD's: Supracristal, Infracristal, para membranous and Inlet VSD's. You also have complete Atriaventricular Canal defect.

[@barbkarangelen4129]

Wow, thank you for a clear description and great diagram! #youcanlearnanything

[@doctazforum7004]

I thought murmur arises from valve defects! how is this possible from VSD?

[@jibanregmi4009]

What about EKG? No mentioning

[@Alexxia1980]

Can you define what do you mean by large, in milimeters... please. Thank you.

[@busybuddy013]

+Bogdan Alexandra Less than 5mm is small. Large is 10-25 mm.

[@hectorfernandes1884]

Good, but could go into more detail!

[@graciouslygrace4782]

Thank you...but it was really way too superficial. You could have covered more details bout the other murmurs.

[@mikerichardson-gray6200]

I have a AVSD and I have a hole in my ventricles

[@akwasiatuahene8433]

I had vsd when I was a baby I got surgery though my mom did crie when I had to get surgery

[@akwasiatuahene8433]

I still have my scar from the surgery

[@collyfeable]

omo kamsa mita 4 this videos😚

[@DrSalvadorContrerasInternista]

Wonderful video !! I subscribe to your channel...

[@emilypaille8704]

Look at that fresh baby XD

[@nizamifaz1107]

I had VSD

[@jamieleanstine275]

I'm 9 and I have (vsd)

[@PhucTran-oz7zx]

Why, in VSD, heart failure occures in left ventricle first???If LV get volume overload, it can push blood to RV via L-R shunt and RV must get this overload..can anyone explain it for me?..thanks so much :)

[@yarahazemgsf8902]

Phuc TranI think because the opening between the two ventricles is not very big to transmit the same pressure from left to right

[@22inominata]

Phuc Tran when the pressure in the RV increases due to the left to right shunting of blood, it will cause pulmonary hypertension. At the end, when the pulmonary resistance becomes higher than systemic resistance, it causes right to left shunting of blood. At this stage, the condition is called as eisenmenger complex.

[@JuicyCharon]

anna inominata Thanks for that. I've tried to understand eisenmenger's syndrome for a while now and it's just clicked when I read your post.

[@22inominata]

L.M Glad it helps :)

[@christinapautu7078]

Why not right to left?

[@newfriendstutorial3157]

bz right ventricle has lower pressure than left ventricle, blood flow through least resistance

[@267cal]

I have this ;-;

[@dawnnorth3535]

Vsd Videos. Only

[@anotherzombie8330]

He messed up his left and right ;-;

[@parth9640]

very very less information

Manu Das haha wish this could be true

[@manudasmd]

@@vyshnaviknair8814 i was already one :p

[@dr.aditirana204]

It looks like a lecture for children, not a lecture for medical students. The way he's speaking, being vague and very less information
