This Video is NOT CORRECT! DO NOT LEARN THIS THE WRONG WAY! The author of this video confused/doesn't understand how shunting works. Left to right shunts are: ASD, VSD, PDA, and Right to Left shunt are known as the 5 T's. A hole in the atrial or venous septum will push blood from the Left to Right because the left heart is more muscular, so it's pump overcomes the right heart muscle, take for example a ventral septal defect; If we start at blood in the left ventricle, when the left ventricle contracts, blood will flow from the left ventricle to BOTH THE AORTA AND THE RIGHT VENTRICLE. Blood will always flow down a pressure gradient, from high to low. The author of this video is saying the opposite and it is incorrect. Also to note, the flow of blood changes if we are talking about a fetus still in the womb (the paragraph above referring to a newborn), because in the case of a fetus, there is an outside pump source providing pressure, and it is the umbilical vein. If this is too confusing just remember that left to right shunts are the 3 D's (asd, vsd, pda),,,, and that right to left shunts are 5 T's ( look them up)
Author is not wrong. You're right ASD, VSD, and PDAs will go left (high pressure) to right (low pressure) but under certain circumstances (anything that switches these pressures) they can go right to left. VSD with pulmonic stenosis or pulmonary hypertension, PDA with a proximal coarctation of the aorta, ASD with tricuspid stenosis. Also initially VSDs go left to right but eventually pulmonary hypertension develops and the right ventricle will hypertrophy and overpower the left ventricle pumping blood right to left (Eisenmenger Syndrome).

Not sure when you said Newborn has hight PVS (Pulmonary Vascular Resistance) and right to left shunt!! Maybe you wanted to say the opposite as the drop in the PVR mandatory in the first few minutes of life to close PFO and establish circulation in series!
I'm sure she meant that the PVR is high as a fetus and during the initial moment of the babies life which is true. One the baby cries and the pressures change then the PVR becomes low and systemic pressure high.
120 is systolic pressure, so thats the max pressure in the arteries that the LV has to pump against to be able to open up the aortic valve and eject blood into the systemic circulation. The 80 is diastolic and that is the pressure in the arteries at rest.
Came from DAT Booster. This video was confusing and hard to follow because of the person's word choice and how she kept interrupting herself. Very frustrating, and unnecessarily so. I think it's pretty important to have a good script to guide your explanation, especially for complicated things like this. This video wasn't very helpful.
OMG I can finally understand this lol...
Very simple explanations that made so much sense, thank you so much!
You explained it in simple way, that is really helpful, thank you somuch
Thank you so much very simple and clear explanation
Very good -- clarified a lot in 9 minutes!
Awesome, this video should have more likes! Thank you.
This is wow thank you so much
Thank you so much, very helpful
The hole you made in the aorta...earlier you said it's supposed to be there then now you are saying it was a technical mistake. Please clarify
She "made" a hole through the atrial septum, not the aorta, so blood flows between the right and left atria.

Very good in short time
You had me, then you lost me halfway.
great explanation
Wow That was SO incredibly helpful! Thank you
Nclex exam is so fustrating can't believe I failed again after studying so hard
Wow that's not fair

I saw someone say he could be a scammer, I couldn't stop laughing, really people say a lot of shit these days
he doesn't have a Facebook page, instagram or RUclips channel , why's that

perhaps she was describing what happens in RDS (respiratory distress syndrome) secondary to decreased lung compliance and subsequent drop in the PO2.
makes sense, thanks
Thanks a lot:)
Good
Which location
@J Mansur u study first then comment
cual es el tratamiento para el shunt en el corazon
No, you got a lot of this wrong, for example if the systolic BP is 120/80, the heart is pumping against a BP of 80 by generating a force of 120 mmHG
120 is systolic pressure, so thats the max pressure in the arteries that the LV has to pump against to be able to open up the aortic valve and eject blood into the systemic circulation. The 80 is diastolic and that is the pressure in the arteries at rest.
