Q

True or false- the MV may “preclose” early with severe acute AR?

A

True

17
Q

With AR, what 3 things may be seen with aortic leaflets with or without m-more?

A

-Diastolic fluttering
- lack of closure of aortic leaflets
-Pre systolic early opening of AV

18
Q

True or false you may see pre-systolic opening opening of aortic leaflets with aortic regur?

A

True

19
Q

LV contractility may be ____ or ____ depending on if it’s acute or chronic

A

Hyper or hypo dynamic

20
Q

What modality is best for Viewing aortic dissections??

A

TEE

21
Q

What causes the MV to pre closure ?

A

Elevated LVEDP

22
Q

Where in a EKG should a normal MV closure happen?

A

Middle to end of QRS complex

23
Q

True or false- you will see systolic flow reversal in the descending aorta with AR ?

A

False. It would be diastolic flow reversal.

24
Q

True or false- you will see diastolic turbulence in the LVOT on Doppler with AR?

A

True

25
Q

How do you obtain the end diastolic pressure gradient for AR? And what is the equation for that?

A

With CW Doppler

Diastolic BP - End diastolic gradient

26
Q

What is JH/LVOT ratio? And how do you get obtain that percentage?

A

It’s the difference between the width of the LVOT measurement and the AR Jet.

You get this number by measuring the LVOT and then measuring the jet to get the difference.

27
Q

What is a Mild JH/LVOT percentage?

A

<25%

28
Q

What is a moderate JH/LVOT percentage?

A

25-65%

29
Q

What is a severe JH/LVOT percentage?

A

> 65%

30
Q

What is a mild AV PHT?

A

> 500msec

31
Q

What is a moderate AV PHT?

A

500-200msec

32
Q

What is a severe AV PHT?

A

<200msec

33
Q

A mild AV jet has a ____ trace on Doppler

A

Incomplete

34
Q

For an aortic regurg jet, the steeper the jet the?

A

More severe

35
Q

On m-mode, how do we know if the mitral valve is pre-closing early due to AI

A

The a wave will be gone.

36
Q

How do you estimate the left intricate and diastolic pressure?

A

With our CW if the AI jet.
Diastolic BP - LVEDp gradient from jet
