Week 3 Congenital Cardiac Disorders Flashcards
what layer gives rise to the CV system
mesodermal
when do the chambers start to form from the tubes
3-4 weeks
in what week do you have a premature heart
week 4
when do you have a fully 4 chambered heart
8 weeks
babies have two small openings between their right and left heart, what are they? what do they do?
they shunt blood from the developing lungs, only 8% of blood goes to lungs. Known as Ducts arteriosus (DO) and foramen oval (FO)
how does the fetus receive oxygenated blood? and where does it send blood back
from the mother by the placenta.
sends back through the umbilical vein
in a fetus, how does blood get from the right atria to the left atria.
through the FO
congenital defects in the heart are usually…
abnormal openings between the adjacent heart chambers.
TF: neurodevelopment disability affects as many as 50% of infants undergoing congenital heart lesions
true
what are some things that will be impaired in kids with cardiovascular congenital defects
social lives developmental disorders organ development issues stroke neurocognitive things.
what are the 3 a-cyanotic defects
atrial septal defect (ASD)
patent Ductus arteriosum (PDA)
ventricular septal defect (VSD)
are the a-cyanotic left to right or right to left
left to right
what is the most common congenital heart defect, and what is it
VSD, a defect in which blood flows from the left to the right ventricle, and there can be increased pressure in the pulmonary artery.
what happens to BP in the UE and LE in kids with coarctation of the aorta
there is different blood pressures in the UE vs the LE. this is because the pinching of the aorta happens distal to the subclavian, so there is lower pressure in the legs, and higher pressure in the arms.
