VSD Flashcards
What direction is a VSD shunt going?
L-R
VSD’s put the patient at an increased risk for?
Endocarditis
What are the 5 VSD types?
I- infundidular
A- atrioventricular
S- subvalvular
M- muscular
M-membraneous
Which VSD is the most common?
Membranous (perimembrabous)
What’s another name for subvalvular VSD?
Inlet
What’s another name for infundibular vsd?
-outlet, supracristal
What’s another name for AV VSD?
Gerbobe defect
What is the gerbobe defect?
A shunt between the LV to LA
Supacristal VSD location is?
Infundibular - near aorta and pulmonic veins
Inlet VSD location is?
Subvalvular - low near TV & MV
What murmur Is associated with VSD?
Loud Holosystolic murmur - LSB
A murmur associated with a VSD will be louder will be:
-louder with a big VSD
-louder with a small VSD
Louder with a small VSD
VSD symptoms will depend on?
VSD size
What are 2 common symptoms of vsd?
- Dyspena
-CHF
What are 3 signs on echo we might see of a VSD?
- RVH
-LAE - VSD aneurysm with windsock deformity
What’s the difference between a restrictive VSD and an unrestricte VSD, especially relating to the Nyquist limit?
- restrictive VSD: a small shunt we use normal color Doppler Nyquist limited detect
-unrestrictive VSD: a large shunt we lower our color nyquist limit to detect
Use ____ to quantify pressure difference between the ventricles for a VSD
CW
How do you estimate the RSVP with a VSD?
Systolic blood pressure - VSD velocity
What will have a higher velocity a restrictive VSD or a unrestrictive VSD?
A restrictive VSD because the shunt is smaller so higher pressure goes through there
What will a restrictive VSD velocity be?
> or equal to 4 m/s
What will a unrestrictive VSD velocity be?
2 m/s
