Question 1

What is the normal aortic valve area?

Answer 1

3-4cm

Question 2

Aortic stenosis is generally asymptomatic until the aortic valve area is ?

Answer 2

<1cm

Question 3

What is the severe jet velocity for the aorta?

Answer 3

> or equal to 4m/s

Question 4

What is the moderate Aortic jet velocity?

Answer 4

3-4 m/s

Question 5

What is the mild Aortic jet velocity

Answer 5

2.6-2.9 m/s

Question 6

What is the mild Aortic jet velocity

Answer 6

2.6-2.9 m/s

Question 7

Where do we get our aortic jet velocity from??

Answer 7

5 chamber, CW Doppler at the Aortic valve. The jet below the valve tells us the velocity

Question 8

Where do we get our mean pressure gradient of the aortic valve from?

Answer 8

We get our main pressure gradient from the aortic velocity we took in aCW

Question 9

What is the severe mean pressure gradient for the aortic valve?

Answer 9

40mmhg or greater

Question 10

What is the moderate mean pressure gradient for the aortic valve?

Answer 10

20-40 mmhg

Question 11

What is the mild aortic mean pressure gradient?

Answer 11

Less then 20mmhg

Question 12

Describe what the dimensionless index for the aortic valve?

Answer 12

It is a ratio of your PW LVOT / CW AV jet = DI

Question 13

The dimensionless index is just another way to evaluate the severity of?

Answer 13

AS

Question 14

What is a severe DI?

Answer 14

< 0.25

Question 15

What is a moderate DI?

Answer 15

0.25-0.50

Question 16

What is a mild DI?

Answer 16

> 0.50
