AS Etiology Flashcards
What is a secondary finding in aortic stenosis?
Left ventricular hypertrophy
With aortic stenosis is pulse pressure wide or narrow?
Narrow.
50% of a aortic stenosis that is calcific or degenerative start as?
Bicuspid aortic valves
What percentage of the population has congenital aortic stenosis such as a bicuspid?
1-2%
Can rheumatic fever affect the aortic valve and result in aortic stenosis?
Yes
True or false prosthetic valve dysfunction can contribute to a aortic stenosis
True
True or false supra, and sub valvular obstructions can cause a word stenosis?
True
True or false supra, and sub valvular obstructions can cause a word stenosis?
True
With aortic stenosis, systolic pressure overload leads to?
LVH
What a work stenosis does the LV suffer from afterload or preload?
Afterload
Eventually, with left ventricular end diastolic pressure increasing that can lead to what?
LA Increased pressure
True or false aortic stenosis is at increased risk for endocarditis
True
True or false ventricular dysfunction may develop quite early within the aortic stenosis disease course?
False. Usually develops later in the disease as the heart compensates fairly well. 
What is aortic sclerosis?
When there is valvular thickening, but no Hemodynamic gradient
