25
On m mode of the mitral valve in a patient that has aortic regurgitation what might you see with the anterior mitral valve leaflet
Diastolic fluttering of AMVL because AI jet is hitting AMVL
26
______ closure of the MV on m-mode may occurs with AI because of increased _____
Pre systolic ; Elevated LVEDP
27
When does a normal mitral valve close in accordance with the Ekg ? And Where would a mitral valve close with aortic regurgitation on M mode?
Right in the middle of the QRS MV would close early or before the QRS with AR
28
What two things happen with the mitral valve on m-mode in a patient with aortic regurgitation
1. Diastolic fluttering of the anterior mitral valve leaflet due to AI jet hitting that leaflet. 2. Pre closure of the mitral valve due to increased LVEDP closing it shut
29
What does M mode of premature mitral valve closure look like?
Occurs before the QRS and a wave is gone
30
What three things may occur with the aortic valve on m mode due to aortic regurgitation?
-diastolic fluttering of the aortic valve -Lack of closure of the aortic valve -pre-systolic opening of the aortic valve
31
Why may diastolic fluttering of the aortic valve occur with aortic regur?
Because of increase the volume and pressure of the regurgitating jet at the aortic valve
32
Why may the aortic valve have a lack of closure with aortic regurgitation?
Elevated LVEDP causes the AV to stay open
33
Why may the aortic valve pre-OPEN insistently with aortic regur?
Because of the elevated LVEDP which does not allow the aortic valve to relax and close. That LV pressure instead continues to have the AV pop open and open early
34
Chronic aortic regurgitation patients need serial echoes to track what?
LV changes
35
True or false- aortic valve or aortic root abnormalities may be present with aortic regurg
True
36
With aortic regurgitation, the left ventricular contractility may be ___ or ___ depending on if the regurg is acute or chronic

What modality is best for diagnosing aortic dissections? A) chest x-ray B)TTE C)TEE D) Angiogram
C) TEE
38
Hyper dynamic LV contractility is indicative of ___ AR
Acute
39
Hypo dynamic LV contractility is indicative of ___ AR
Chronic
40
With AR there is ____ turbulence in the LVOT

41
With AR. What might our with the blood flow within the descending aorta?
Diastolic flow reversal
42
Map the Regurgitant area of AR with what 2 things?
PW & color
43
How do you estimate LVEDP?
You get the end diastolic gradient with CW Doppler Diastolic BP - End diastolic gradient
44
The formula : Diastolic BP - End diastolic gradient is for what?
To Determine LVEDP
45
What do you need for the JH/LVOT ratio work?
LVOT measurement in PLAX & AI JET width in PLAX (vena contracta of AI)
46
JH/LVOT calculation is comparable to ___ like we use for the MV
PISA
47
What is the JH/LVOT mild, mid & severe valves?

48
What’s the mild, mod & severe of Vena contracta AI jet?
Mild= <3mm Mod= 3-6mm Severe= >6mm
49

52
A mild AR jet will will have a ____ trace of Doppler
Incomplete
53
The steeper the aortic regurgitate jet is, the faster the ______ which means the more ____ the AI

70
How do you calculate pulmonary artery end diastolic pressure when they give you a right atrial pressure and a EDV? Ex: patient has a RAP of 8 mmHg and a EDV of 2.7m/sec What’s the PAEDP?
