Congenital Heart Diseases- Batten Flashcards
most common birth defect
congenital heart defect
what resistance is high at birth and then falls once
Pulmonary Vascular Resistance (lungs not being used in the womb)
what causes fluid in lungs w/ heart defect
L to R shunt of blood causes backup in the lungs
what usually closes within 3 days of birth
PDA
what resistance increases at birth when umbilical cord is clamped
systemic vascular resistance (SVR)
result of this shunt is pulmonary overcirculation
L to R shunt
infant presents w/:
tachypnea
worried face
diaphoresis
crackles
poor weight gain
hepatomegaly
pulmonary edema + cardiomegaly on CXR
L to R shunt (CHF)
what can L to R shunt lead to later
pulmonary HTN
what syndrome can arise from L to R shunt that reverses to R to L shunt after a while; cyanotic
Eisenmenger syndrome
Rx for infant with CHF
diuretics (decrease preload)
ACEI’s (decrease afterload)
type of L to R shunt that has perimembranous type as most common
VSD
_____ septal defect can cause more pressure in RV and then pushed into pulmonary a.
ventricular
harsh holosystolic murmur heard at LLSB (S1 and S2 hard to hear)
VSD
Patent foramen ovale
secundum ASD
primum ASD
flap of foramen ovale made out of what
septum primum
