Tetralogy of Fallot.avi

[OrangIndonesiaAsli9]

Would the treatment for this baby's case similar to that of Tetralogy of Fallot? If so what do you think the treatment should be and when it should be done? Thank you.

[OrangIndonesiaAsli9]

Examinations were therefore performed and it was found out that she has got heart problems which is very similar to what you are describing here, WITHOUT the overriding aorta (because from the echocardiogram result, it seems that the aorta is correctly positioned over the left ventricle).

In summary, she has got MEDIUM pulmonary stenosis, MEDIUM vsd, MEDIUM right ventricular hypertrophy, and TINY atrial septal defect.

Hi JPShand, thanks for uploading this excellent video. I have a couple of questions that I hope you would be able to help me with.

A baby (only a few days old) is found to turn blue in her lips and face, ONLY when she cries. During other conditions, her color is normal reddish (with NO PROBLEM in feeding and NO rapid/short breathing).

[Ositobobito]

Excellent video! Thank you!

[taurus35]

really comprehensive and explanatory idd.finally got some important points via this video what my professor couldnt teach properly enough

[annette020]

thank you for your VERY thorough explanation! Do more videos of the heart :)

[karlalorena1302]

hola soy de Ecuador me encanto el video :)... Hi, Im from Ecuador really loved this video thak u so much, youre doing medicine easier...

[sordidfate]

Hi. Im just curious about the pathophysiology of CHD child who has severe malnutrition?

This video is great btw. :)

[leojacj1]

great vids!! may u explain the shifting position of cardiac apex in case of rt n lt ventricular hypertrophy ?igot confused a lil ::)

[clarvery]

Thanks a lot



[mrpowell0981]

thank you

[amerribhi]

Thanks a lot ,appreciate the help :)

[prtysha07]

Thanks!! Can you make a video on Ebstein Anomaly please?

[KGilles100]

This was really helpful. I completely understand Tetralogy of Fallot now. Please post more educational videos. Thank you, thank you so much!!!

[wlaa2009]

you are amazing !! 

[nucleola]

dude you're awesome! this helped alot, thanks so much! :D

[HugAmango]

Hello you were right the first time about etiology. According to first aid 2011 and Robbins and Cotrain Pathlogy its anteroSUPERIOR displacement of infundibular septum.

[YUSHIU5]

Awesome explanation on Tetralogy of fallot!

[Abster1911]

very good & clear explanation! thanks!

[spoekr8]

Excellent explanation!! Better than my professors...kind of depressing since youtube is free.

[Malagu40]

This video explained all 4. Very good. Thanks

[jenniferw87]

I am an adult TOF. This is great. I remember "squatting" as a child. 20 years ago I had total correction done.

[shahdehbomb]

you're a friggin genius! you should seriously make more videos man this has made my life so much easier! Encore S'il vous plait <3

[alanheadbloom]

Spelled: hypertrophy

[RobertDavidStevenson]

This really helped me learn ToF for my exams.  Thank you!

[nodoctoryet]

Thanks alot Dude, appreciate it!!

[UberJerkyNerd]

Thanks!

[kareecemoonasingh]

This was very helpful! Thanks for the mnemonic

[were455]

very nice video? Are you a doctor? I think you definately know what you are talking about.

[TheAnaRayAna]

Certainly did learn something. One of the best explanations ever. Thank you!!

What is the reason for the syncope episodes. If most of the blood goes up the aorta feeding the carotids, and the PA feed the lungs, would that cause dyspnea and only with severe decrease in O2 sats cause the episode.

[JPShand]

Hello!

The deoxygenated blood that is returning to the heart from the body (via the superior/ inferior vena cava) is supposed to be re-oxygenated by the lungs (via the pulmonary artery). But, it is not because of the stenosis. Instead, this deoxygenated blood is re-routed back to the body (through the aorta)! Alas, this deoxygenated blood cannot feed the brain the oxygen it needs, the reticular activating can't function without proper oxygenation and thus it shuts down, resulting in syncope.

[JPShand]

Thank you for the question!

Everyone should feel free to ask any more questions you want answered here.

If anyone wants me to explain any other disease processes in a new video, please ask! I'll do it!

Or at least, do my best!

Thank you all for all your great feedback!!

[anickad5]

About the hypercyanotic attacks that occur when crying, it happens because the sympathetic response causes an increase in the pulmonary stenosis (the pulmonary stenosis is actually a right outflow tract obstruction). Sympathetic stimulation of the heart actually worsens the right outflow tract obstruction, worsening the pulmonary stenosis and causing increased PVR, increasing the right to left shunt and causing them to become blue. 

[JPShand]

@anickad5 Absolutely, excellent addition! @pdmc5521 this helps answer the question as to why the syncope occurs during the tet spell.

[kblossomsk]

i have a question. i m a final year student. just wondering y would we give fuilds to the child? the right ventricle is already hypertrophied, shouldnt we be giving diuretics? n if not, y not? plz guide

[llkwaigone]

Awesome explanation. Thank you.

[blacklibra0175]

Very well explained; good organization and coordination of information.

You made it easier to understand. Thank you sir! :)

[Fontaineiii]

I really like this explanation. I am a student as well, and have a test on Congenital Heart Defects this week. Helped a lot! thanks!

[bigsella86]

Great explanation, helped me immensely in trying to understand tet spells. Thanks for the great vid!!!

[teachmeanatomy]

THANK YOU SO MUCH!!!

[spicyjampong]

a little boring but good effort..

[BabylonLynx]

lol, nice, i have a pathology exam tomorrow and i was looking for a right to left shunt video and i look at the uploading date... hahaha how lucky am i, if i had my exam a week ago i would have not seen this video, thx alot, a real great effort, thx

[shalshah]

Nice! How does squatting prevent the overriding Aorta from getting the deoxygenated blood? Does it increase the pressure in the left ventricle and force blood into the Pulmonary artery?  Is that what you meant by afterload?

[JPShand]

Exactly! Increased afterload via crimping of the femoral arteries will increase the pressure against the LV ejection, and therefore push blood toward the area of less resistance (which upon squatting became the pulmonary artery). Before the squat, the path of least resistance was through the over-riding aorta.
