Patent ductus arteriosus | Circulatory System and Disease | NCLEX-RN | Khan Academy

Patent ductus arteriosus is a medical condition where a blood vessel called the ductus arteriosus does not permanently close after birth. Learn why the ductus arteriosus does not close, why patients with this condition have a wide pulse pressure, and how the disease is treated with surgery and nonsteroidal anti-inflammatory drugs (NSAIDs).

I cannot tell you how helpful your cardiac videos have been! I literally wrote notes on CHDs over and over and still didnt understand the material, after watching these videos, I totally get it! So lucky to have these, now let's hope I ace my test on Tuesday!

[@LaurenRogers59]

I was born 24 weeks premature in 2000 I was the smallest baby in Essex UK. I had a PDA, bleeding on the brain and multiple other things. When things happen in life when you nearly died. It makes you appreciate life a lot more xxx

[@ilikefunnyvideos]

If my future patients knew how much of my education I have gained from KZbin and specifically Khan Academy. They would be shocked. KZbin > Boring Book. #MedSchool

[@cristinacabalquinto6896]

Lol, same here and Im in nursing school :) books are too bland

[@sorayamoharamzade6199]

Same here!

[@SasSaga]

You all the BEST information on the web. I am currently studying for my pediatric echo exam, and your videos bring all of the written information together for me! Thank you!

[@YouPube_X]

One of my 11 week premature twins (the girl) might have this, murmur detected. Echo scan scheduled for tonight. This video helped a lot with understanding the problem. Thanks.

[@LeratoLANGAMLAMBO]

Loving these lectures everytime I see them. Easy to follow. Simplified

[@amandamoring]

This is excellent!!! Thank you SO much!! It is difficult for me to picture something if I just read it in a text. This really brought PDA to life. Thank you!

My Dachshund has Patent Ductus Arteriosus. He's just a puppy, but has a hard time eating much and is very, very small for his age. Anytime he whines or eats he pants a lot. He seems to be always panting, no matter what he is doing. He sleeps a lot for a puppy. He has a very rapid heart rate and his gums and tongue often turn blue or dusky color. When he was 8-weeks-old my veterinarian told me to wait and see if his PDA would close on it's own. When he was 12-weeks-old he put him on an NSAID to help close it. He is now 16-weeks-old and it's still open, so he will be undergoing open-heart surgery in one week. We may wait until he is 20-weeks-old so he could have a catheter procedure, which is much less invasive. My poor puppy is on constant antibiotics to keep him from getting a heart infection. I have to brush his teeth every single day and his teeth are checked monthly by a vet. He's been on antibiotics since he was 8-weeks-old in order to prevent infection. I can't let him play or exercise much either. Unfortunately, he came from a bad breeder and that is why he has PDA. His breeder didn't know her dog was pregnant until she was about ready to give birth. She fed her dog a raw diet, which is nutritionally unbalanced. She never even took the poor thing for a walk. That is why my poor puppy was born with this terrible condition.

[@natura1971]

Thanks so much!

[@fatboy117]

thanks... I always for get the physiology to this pathology.. but it was a great video.

[@anesthesiologistma8373]

u make it clearly.thank u so much.

[@shiroles1228]

thank you sir for the explanation i watch your video its open my mind, cause i can't imagine whats happening if i only read the text book but sir can you please add the complication to your other video? :) oh btw your ASD and VSD video its nice to !!!!

Awesome instructor!

[@cristiangdc618]

Thanks for the great explanation.

[@ChrisHeightsTV]

Thank you! 🔥🙏

[@bellehpham7742]

For the treatment, I was wondering what about O2? Would they do anything to increase O2, and would that close the ductus arteriosus?

[@soniamartell9220]

Awesome video! As always!!!!

[@farzanamirjat817]

Amazing khan Academy.

[@taeniasolium2714]

Hello Sir , thanks a lot for the video but I have a question regarding DBP. We say that DBP mainly depends on Total peripheral resistance. Would you please elaborate DBP change in regard to TPR ????

[@Peace2920]

Wonderful!

[@sindhu3294]

Really good explanation sir... did not get this kind of explanation in any other videos.... Thank you so much for that... just a small suggestion... in the black background, dark colour like red does not show out well which makes it tough to see wat you are writing....sugessting you to use brighter colour like that of the heart... hope you do the needful Thank you! ❤

[@vineethkondapally9240]

Sir can you please explain about hypoplastic left heart syndrome in detail

[@tashik8151]

Is the pulse high volume or low volume?

[@venkybly]

Tq

[@tiffanyedwards8345]

Closure is due to a high level of prostaglandins, not low. Hence why they administer more prostaglandins as a treatment for closing the PDA in infants

[@robintrumble1101]

Sorry, you've got it backwards. Drugs like Indocin are given to close a PDA. Prostaglandins are given to keep a PDA open.

[@ericapatton4872]

@@robintrumble1101 Agreed!

[@ziyandashozi7905]

Agreed! Prostaglandin keeps it open,

[@Welldressedfe]

why we don't close the ductus arteriosus if we have pulmonary HTN ? any one can explain thanks

[@alcaponed16]

Why would SVR decrease in PDA?

I was born at 24 weeks, also was a twin, and sadly my twin didn’t make it, but I had to get this surgery. Sometimes I have seizures, and I’ve been tested for them and nothing abnormal. But I think one time a nurse said I had a murmur when I was younger. And I mentioned To my mom that I remember a nurse saying I had a murmur and should get it checked out, but my mom didn’t believe me so we kinda just forgot about it. I have palpitations a lot, and I’m pretty much always aware of my heart beating cause it’s always fast and hard. Like I can constantly feel it. Should I tell my doctor about it? Or is it just something I just need to deal with?

[@Dr_Okonji]

Nice video, however you could have been more specific with the NSAIDS used in this case which is indomethacin.

[@DrArjunKataria]

you are right . i was also thinking on that.

[@MmM-pr5cn]

Actually, ibuprofen and even paracetamol can also be used to treat it, so I think leaving it just NSAIDs is more okay.

[@zana43]

can you explain why there is a wide pulse pressure

[@Domowoj]

He does...pay attention to video starting at minute 6 through minute 7.

[@jackripper2]

I'm 25 yrs old and just have my PDA closed recently with device closure. I thought I would feel better after closing my PDA, I'm still having dyspnea and back pains at the same time. I can not do my normal work without having problems. I wonder what could b the reason? I'm feeling dissatisfied.

[@madhukarreddykatam3122]

Whats size of PDA

[@samphonnetgamgee5625]

The diastolic pressure goes down??? I would have said the systolic.

[@madhukarreddykatam3122]

Hello all, my baby has PDA Is there any chance to close without medicines and surgery. Please reply

[@madhukarreddykatam3122]

Few are telling by growing it closes automatically

[@Weyzeful]

Could someone tell me if I'm right ? I understood that when the baby is not born yet, there is higher pressure in the right part of the heart so the blood goes from the pulmonary artery to the aorta through the ductus arteriosus. But when he is born (and if he has a patent ductus arteriosus), the pressure is higher in the left side so the blood goes from the aorta to the artery pulmonary.. Is that right ? I'm really struggling with that and I can't find a clear answer to it (sorry for the spelling mistakes, I'm french ^^)

[@DrArjunKataria]

yeah you are right in placenta- blood comes from ductus venosus to the heart and it goes to rght atrium from there it goes to right ventricle and left atrium (fossa ovale). so from right ventricle it goes to lungs via pulmonary arteries, while lungs are not functioning but still they need blood for oxygen and nutrients; patent ductus arteriosus helps blood drain from p.arteries to aorta and from there return to mother via 2 placental veins. while after getting birth ,lungs start their function so no need to drain blood from p.arteries to arch of aorta anymore so it should be clossed soon.

[@DrArjunKataria]

in placenta i mean place , not a placental Artery.

[@undercoverelixir9975]

Weyzeful hey, good question ! Once the baby is born umbilical cord is clamped & there is loss of placental circulation so blood volume in right atrium is decreased and right at trial pressure is decreased. Systemic vascular resistance increases and as a result left atrial pressure is more than right atrial pressure, because of which foremen ovale closes. Sudden expansion of the lungs decreases pulomonary vascular resistance and hence aortic pressure is more than pressure in pulmonary trunk, so blood flows from aorta into pulmonary trunk through ductus arteriosus if it remains patent

[@Weyzeful]

Thank you for your responses ! :)

[@mainakdey7739]

❤️✌️😊

[@nabilalk]

I had high hopes for this video because it's Khan academy. However, I have to say that I was very disappointed. The speaker is all over the place, it doesn't seem like he has a clear plan, and his explanations are way too drawn out and disorganized. I would recommend redoing this video, make it more concise, and also talk about what happens with an open PDA ie Eisenmanger's syndrome. Also, talk about how a PDA is beneficial in a TOF patient.

[@bellehpham7742]

I think you would need to read the lecture or do the homework of this video first before you watch it. For me, this tremendously helps me understand my lecture. So much clearer and easy to remember as to understand.

[@hopem8077]

This guy acting like a friend explaining stuff to you not like a lecturer who wears starched suits and sounds like background noise
