Flashcards in Aortic valve disorders Deck (11):
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.
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

Characteristic of carotid pulses - aortic stenosis vs sclerosis
aortic stenosis - slow and delayed ("pulses parvus et tardus")
aortic sclerosis - normal
Aortic sclerosis progresses to ________
aortic stenosis --> heart failure
Which AVD occurs in newborns +?
