Flashcards in Aortic valve disorders Deck (11):
1

Why should you use caution with drugs that reduce pre-load in patients with aortic valve disorders?

Cause decrease filling in left ventricle which can increase syncope because less volume.
*diuretics, nitrates

2

Why should you use caution with drugs that reduce after load in patients with aortic valve disorders?

Can become easily hypotensive
*ACE inhibitors, alpha blockers, nitrates

3

What AVD is a congenital abnormality of the bicuspid valve or calcification/degeneration of the tricuspid valve?

Aortic stenosis

4

What AVD is a thickening of the aortic valve?

Aortic sclerosis

5

Characteristic of murmur - aortic stenosis vs sclerosis

both: upper right sternal border
aortic stenosis radiates to the carotids (aortic sclerosis does not)

6

Characteristic of carotid pulses - aortic stenosis vs sclerosis

aortic stenosis - slow and delayed ("pulses parvus et tardus")
aortic sclerosis - normal

7

Aortic sclerosis progresses to ________

aortic stenosis --> heart failure

8

Which AVD occurs in newborns +?

aortic stenosis (bicuspid)

9

Which AVD occurs in the elderly?

aortic stenosis and aortic sclerosis

10

Imaging of choice for AVD

ECHO

11

AVD AKA aortic insufficiency…"blowing" diastolic murmur, brisk pulse with rapid collapse, head nodding with heart beat

aortic regurgitation
