|
how is the IVC presented in left atrial isomerism?
|
Interrupted with dilated azygos vein located posterior to Ao on same side of spine
|
|
|
how is the IVC presented in right atrial isomerism?
|
anterior to Ao on same side of spine
|
|
|
Pulmonary artery pressure rises in response to
|
^ flow volume and/or pressure as PVR ^
|
|
|
^ flow volume and/or high pressure causes the intimal and medial layers of the pulmonary aterioles to
|
hypertrophy > ^PVR
|
|
|
with prolonged exposure to ^flow vol /pressure, the pt develops PHTN and eventually
|
pulmonary vascular obstructive disease which is IRREVERSIBLE
|
|
|
when Pulmonary artery pressure exceeds systemic pressures, blood flow through intra/extracardiac....
|
reverses so that they become pulmonary to systemic or R-L shunts.
|
|
|
the RV eventually fails bc
|
f the increased resistance against which it must work to eject blood out
|
|
|
in PHTN, the RV is
|
dilated/thickened
|
|
|
systolic PA pressure
|
4(tr)2 + 7mmhg
|
|
|
diastolic PA pressure
|
end diastolic PI + 7mmhg
|
|
|
mean PA pressure
|
acceleration time divided by ejection flow (PW)
|
|
|
ductus arteriosus connects LPA to desc Ao at what level?
|
immediately distal to left subclavian artery
|
|
|
PDA is increased in what population?
|
preemies, rubella syndrome,
|
|
|
what are surgically created systemic to pulmonary shunts? Name 5 and describe
|
BT: subclavian artery-PA on side opposite of Ao arch
Central: SVC-MPA Potts: Des Ao-PA Waterson: Asc Ao-PA |
|
|
is subaortic stenosis seen in ASD?
|
yes
|
|
|
what is another name for supracristal vsd? and what can happen to the aortic valve?
|
double commited subarterial, subpulmonic, aortic valve herniation (prolapse) and AI
|
|
|
what is anomalous orgin of LCA?
What will you see in echo? |
-LCA originates from MPA and myocardium of LV is inadequately perfused w/deO2
-dilated RCA, MR |
|
|
What is coronary artery fistuala?
|
a variably tortuous coronary artery that empties into a cardiac chamber or gereat vessel. it is usually RCA and usually affects right heart
