44 Coarctation of the Aorta, bicuspid aortic, aortic root dilation


Hey, guys. It’s Nanette with HeartBabyHome. Today we’re looking at heart #44 and I see most of the defects are
surrounding the aorta. so let’s start up at the top with the coarctation of the aorta. “coarctation” means “narrowing” and it’s just where the aorta gets pinched right after the arch and that’s right where the blood goes
out to the body so it just makes it harder for the blood that’s carrying oxygen to get out to the
body. Now let’s talk about the PDA – Patent Ductus Arteriosus. that’s an extra passageway between the aorta and the pulmonary artery and that will allow blood to flow both
ways depending on which way the pressure is now adults don’t usually have that (or even kids). That’s something that you have when you are a fetus and it usually closes 2-10 days after you are born So, sometimes that will let surgeons have a few extra days before they have to do
a surgery. Sometimes they have to actually go
in and close it up. It’s not something that normal heart should have Next I see (AD) aortic root dilation. Ok, so the root of the aorta is where it leaves the heart–where it leaves the left ventricle. so if you look right behind the valve, the aorta is bigger right there or “dilated”. now it’s not an aneurysm — so it hasn’t blow up on the side like a balloon or anything. It’s just a little bit bigger
than it should be. Then we also have a BAV – that’s a bicuspid aortic valve and that’s where…so, the valve right
there has three parts to it… and all three of the parts open and
close and that’s what makes it a one-way valve. So the blood can go out to the aorta but it won’t come back into the left ventricle through the aorta. But in this heart, bicuspid…. “bi” means “two” and so that means two of those leaflets
have fused together. So instead of having three parts, it only has
two parts. and so that makes it harder for the
blood to get in because it’s like a doorway that only opens halfway. Then we have (as) sub-aortic stenosis. and that’s where the blood flow is limited below the aorta because there’s an extra
membrane below the valve. And then There’s also a PFO – which is a Patent foramen ovale and that’s a lot like an ASD – which is a hole between
the two atria…. but instead of a hole, it’s a flap. So then anytime there’s pressure, then that flap can open — so like if you cough or
sneeze or sometimes if there’s just lots of pressure and heart then that will open. Sometimes those close up on
their own and heal up and sometimes they have to fix those surgically. and it looks like that’s it for heart #44. thank you for watching please subscribe to a channel if you
