Q

Where are artery and vein on lateral?

A

Artery dorsal to vein

20
Q

What size are artery and vein on lateral?

A

Same diameter, no larger than 4th rib

21
Q

What pattern do dogs get in pulmonary over-circulation?

A

Peri-hilar then alveolar

22
Q

What pattern do cats get in pulmonary over-circulation?

A

Alveolar, then effusion

23
Q

What do laminar and turbulent flow look like on pulse-wave Doppler?

A

Laminar flow has white outline, turbulent is filled in

24
Q

On a lateral, where are the R and L chambers?

A

Right chambers are cranial and left chambers are caudal

25
Q

What causes concentric hypertrophy?

A

Pressure overload (increased systolic pressure)

26
Q

What does concentric hypertrophy look like?

A

Wall thicker, but chamber size remains the same

27
Q

What causes eccentric hypertrophy?

A

Volume overload (increased diastolic pressure and volume)

28
Q

What does eccentric hypertrophy look like?

A

Dilation, lumen size increases, ventricular size the same then thins

29
Q

What are the three types of Doppler?

A

Pulse waved, continuous wave, colour flow mapping

30
Q

What is an advantage and disadvantage of pulse wave Doppler?

A

Not high velocity, but specific location

31
Q

What is an advantage and disadvantage of continuous wave Doppler?

A

Measures high velocities, but not the specific region

32
Q

What measurements can you take on M mode?

A

End systole at nadir of septum, end diastole at onset of QRS, fractional shortening

33
Q

How do you calculate pressure gradient?

A

4 x max velocity ^ 2

34
Q

What affects fractional shortening?

A

Heart rate

35
Q

What values indicate mild, moderate or severe stenosis?

A

Below 50 = mild, 50-100 = moderate, over 100 = severe

36
Q

What is at 11-1 on DV rads?

A

Aortic arch

37
Q

What is at 1-2 on DV rads?

A

Pulmonary artery

38
Q

What is at 2-3 on DV rads?

A

Left auricular appendage

39
Q

What is at 2-5 on DV rads?

A

Left ventricle

40
Q

What is at 5-9 on DV rads?

A

Right ventricle

41
Q

What is at 9-11 on DV rads?

A

Right atrium

42
Q

What is at 12-2 on lateral rads?

A

left atrium

43
Q

What is at 2-5 on lateral rads?

A

left ventricle

44
Q

What is at 5-9 on lateral rads?

A

MPA and right auricular appendage

45
Q

What is at 10-11 on lateral rads?

A

Aortic arch

46
Q

Which IC space for ultrasound views on the right?

A

3rd-6th
