AR Flashcards
What are a few etiology’s of aortic regurg?
- primary cusp disease like stenosis, SBE, arthritis
- dilated AO root and annulus
-loss of composure support like dissection, VSD, trauma
Which syndrome goes with aortic dissection?
Marfans
Is ankylosing spondylitis a cause for AR?
Yes
What is SBE? And is it a reason for AR?
Subacute bacterial endocarditis and yes
Loss of commissure support for the aortic regurg includes what three things?
- dissection
Membranous VSD
-trauma
What are two things that occur due to AR?
-LV dilation & LV volume overload
- decreased EF w long standing regur
Does aortic regurg have a narrow or wide pulse pressure?
Wide
What kind of murmur is heard with aortic regurg?
High-pitched blowing diastolic murmur
What are four symptoms of aortic regurg?
- CHF
-syncope
-DOE
-angina
What is a physical sign you may see with aortic regur having to do with arterial pulses?
Bounding arterial pulses ( heart feels like it’s pounding more strongly)
What kind of murmur would you hear in a patient with a rupture of a sinus of Valsalva aneurysm?
Continuous murmur
Aortic regur can cause what famous type of murmur?
Austin flint
The Austin Flint murmur associated with AR sounds more like which other murmur?
MS- opening snap diastolic rumble
M-mode may show what 2 things with the MV leaflets during AR?
-Diastolic fluttering of MV leaflets.
-Early closure of MV leaflets due to LVEDP
If there is diastolic fluttering of the mitral above leaflets during aortic regurg, which leaflet is most likely to be affected?
AMVL
True or false- the MV may “preclose” early with severe acute AR?
True
With AR, what 3 things may be seen with aortic leaflets with or without m-more?
-Diastolic fluttering
- lack of closure of aortic leaflets
-Pre systolic early opening of AV
True or false you may see pre-systolic opening opening of aortic leaflets with aortic regur?
True
LV contractility may be ____ or ____ depending on if it’s acute or chronic
Hyper or hypo dynamic
What modality is best for Viewing aortic dissections??
TEE
What causes the MV to pre closure ?
Elevated LVEDP
Where in a EKG should a normal MV closure happen?
Middle to end of QRS complex
True or false- you will see systolic flow reversal in the descending aorta with AR ?
False. It would be diastolic flow reversal.
True or false- you will see diastolic turbulence in the LVOT on Doppler with AR?
True
