Great video, as additional point, the blood can still get the lungs if instead of a VSD there is a patent ductus arteriosus present.
came here to say this
Then why it shows grade III / IV ejection systolic murmur in the left sternal border than continuous murmur if ductus arteriosis is patent
I have Tricuspid Atresia and this is the first time in my almost 30 years I've actually understood it lol
Same!
have you gotten any other surgeries like what age was your last surgery
Dude me too and I still only kind of understand it
Thanks for all your videos. You do an amazing job!
Thanks so much, greatly appreciated.!!!
Thank you SO MUCH for this video. I'm the director for an orphanage in Uganda and we just had our first baby with this. Unfortunately, there's no doctor in this country who can perform this surgery, much less explain what it is in a way we can understand, so we'll have to find a way to get him to another country that's capable and still open for international travel (because ... you know ... Covid).
That baby should be taken to the Rocky Mountain Children's Hospital in Denver Colorado and the surgeon Dr. Steve Leonard should fix it
super helpful! thank you!!!
I had a brother born with it in 1960. He passed away. Surgery for this has come a LONG way!
thanks a lot. i am clear about it.
I actually have Tricuspid Atresia. I’ve had 5 Open heart surgeries before I graduated High School. And I have to go to a Cardiologist every 6 months to check up. It’s pretty sad but Cool. I’m proud of it.
And this Video is very Accurate.
King Jacob I have tricuspid Atresia too and I’ve had more than 8 open heart surgeries and I’m only 18
I must have been really lucky compared to you guys, wow. I had 2 open-heart surgeries (at 9 months and then at 5) and two more (at 7 and then 15) for abdominal pacemakers. I'm now a few weeks shy of 23.
I don't remember mine as I was very young, but a few years a go they has to to a cardiac catheter procedure on me to but a coil to block up a burst/leaked vein, and a stent to regulate blood pressure in my arteries that was making me cough blood up. I get very tired often but I am lucky to be healthy. Mate, I know this is late but hope you're doing well and good luck. Just felt like sharing my experiences.
@@LeroyW70 my baby born with tricuspid atresia can please share your experience after surgery?
@@bunnyaom I am able to live a fairly normal life, however I run out of breath real quick, I have to take some medication for the condition (warfarin). Over working causes alot of chest pain sometimes and difficulty breathing. I can't go on fast rides (e.g rollercosters) but apart from that I'm okay. You child may experience haemoptysis approaching puberty. Call the emergency department and explain. It will most likely be a burst or weak vein. This is from experience. Your c3h3ils may not have this and this may be irrelevant. Apart from that, they should be able to live a relatively normal life assuming they eat healthy and exercise often. But not too much.
Thank you for your effort
I've it and it's so cool to understand it through and through, I've gone through Fontan surgery and extracardiac Fontan surgery 20 years apart.
Amazing video. I understand it so well with your illustrations and explanations. Learning the pediatric heart defects are such a doozy for me but love this video!
Thank you so much
very direct to the point. explained very well. Thank you
Very good explanation!
Very useful
Perfectly explained... couldn't understand how the lungs is working despite Pulmonary valve being hypoplastic...Clear concepts now🔥🔥
Beautiful explanation 😌🙌
but doesn't an ASD classically lead to a left-to-right shunt? wouldn't the purpose of shunting blood from the right atrium to the left atrium be defeated be defeated?
Thank you
perfect
Awesome ❤️
Great video, helpful for the incessantly busy PA students such as myself haha.
My boyfriend actually has this and he's doing pretty darn well considering. Thankful to live in a place with one of the leading hospitals in the World. University of Michigan saved his life, my life, and so many others!!
How does l.v receive o2 blood if the blood can't reach right ventricle???
Great explanation ❤❤❤❤
nice thanks
Thanks.
Good
Thanks for the great explanation and information. Have some questions:
1. Based on all of this information, I would suspect that there would have to be right atrial hypertrophy that would result from the pressure differences. (I don't think she mentions that in the video, sorry if she did.) Is this the case? If not, how does the blood from the right atrium overcome the pressure in the left atrium to cause the right to left shunting?
2. How do electrical impulses change in this scenario? How do the impulses from the atria reach the Bundle of His if so much of the septum is missing? Do the pacemaker cells still manage to send the impulse down the normal pathway (SA-Bachmann's Bundle-AV-Bundle of His-Left & Right bundle branches-Purkinje Fibers) or does the heart have a ventricular rate?
3.) Also, does what remains of the right ventricle contract despite being empty?
4.) If the body is being supplied a lower amount of oxygen due to the mixing of blood, does this cause the left ventricle to hypertrophy and work harder to try and compensate for the lower oxygen concentration?
Sorry for all of the questions.
There is no mitral valve so the right ventricle never develops! So the hole in the septum allows blood to go to the lungs then come back through the left atrium as "purple" blood and get to the body through the aorta.
You mean, there is no Tricuspid valve?
yes, no tricuspid valve, apoptosis didn't occur so the leaflets didn't form. Instead there is just tissue where the valve goes so there's no way for the blood to go from the right atrium into the right ventricle, this is why the right ventricle doesn't develop.
yes there is left ventricle hypertrophy...but hypoplastic right ventricle...
Wish I could think like you, Amanda.
Great explanation of TA; but you did not talk about role of PDA in patients born with TA
Instead of the VSD, the system would still work with Patent Ductus Arteriosus right?
The only way for blood to get to the lungs without a vsd would be retrograde flow from the aorta into the PDA. This could technically “work” but there would be cyanosis
Why should there be an ASD to fill the left ventricle? According to the video, pulmonary veins fill the left atrium with the blood derived via the VSD. So what role is the ASD really playing?
ok, i guess the right atrium needs an outlet so thats why..
The pressure from the inflow of blood from the IVC and SVC into the right atrium would likely cause PFO... the blood needs somewhere to go
Is tricuspid atresia and HRHS the same thing?
HRHS is caused by TA. I should know, I have it. I’m doing well.
I have this disorder it’s hell
I want to ask a question if any one can help , why the blood doesn't move from the RT ventricle to the LT ventricle although we have ventricular septal defect , I am really confused.
I think because the blood moves from the high pressure area to the low pressure area and since the left ventricle have a higher pressure than the right ventricle the blood will move from the left to the right ventricle ( high pressure to low pressure area).
I’m not really sure about this but I think that is the answer, hope that helps
What happens when there is also a severe pulmonary artery stenosis?
The baby would most likely be given a Blalock-Taussig shunt, which usually runs from the right subclavian to the pulmonary arteries. This begins the Fontan Procedure. In a later surgery the infant will be given a bidirectional Glenn, or rerouting of the superior vena cava to the pulmonary arteries. At this point the Blalock-Taussig shunt is usually taken down. The VSD may be closed here as well. Lastly will be the Fontan, or rerouting of the inferior vena cava to the pulmonary arteries. Now the ASD can be closed as well because nothing is returning to the right atrium. This procedure eventually bypasses the right side of the heart completely and relies solely on the left ventricle.
Thank you for the clear answer so quickly!
I have tricuspid Atresia and I hate it......
ItsLouise Videos haha. don’t we all
ItsLouise Videos I just had a daughter that had it and went through 2 surgery’s already why do you hate it?
