embryology of the heart: failures
incomplete septal wall closures
atrial septal defects
ostium primum
sinus venosus
ostium secundum
coronary sinus defects
ventricular septal defects
tetralogy of fallot
right ventricular hypertrophy:
increase in size of right ventricle
overriding aorta:
displacement of the aorta
pulmonary stenosis:
constriction of pulmonary artery
VSD:
hole in the ventricular septum = oxy and deoxy blood mix when they should not
fetal circulatory shunts that didn't close by birth
PDA defect (after birth)
the ductus arteriousus stays open:
deoxy blood from the pulmonary artery escapes to the aorta
PFO defect (after birth)
the foramen ovale stays open:
blood from the right and left atria mix
coarctation of the aorta:
narrowing of the aorta
malformation of the 4th and 6th aortic arches
other
blue baby syndrome
