VALVE DISEASE AORTIC
REGURGITATION



# TERM DEFINITION


1 What are the etiologies of aortic
regurgitation?
-HTN, degenerative valve
disease, bicuspid aortic valve
disease, rheumatic fever,
ankylosing spondylitis,
dissection of aorta, aortic root
dilation (Marfan’s syndrome),
aortic aneurysm, aortic
dissection




2 - HTN- increased PVR leads to
backflow of blood
What is the number one cause
of aortic regurgitation? How
does it work?

, 3 calcification can prevent valve
How does degenerative valve from closing properly
disease cause aortic
regurgitation?


4 mitral regurgitation
What is the effect of aortic
regurgitation on the LV similar
to?


5 What is the regurgitant fraction?
portion of blood leaving the
aortic valve and returning back
into the LV


6 What does the increasing
regurgitant fraction lead to in - LVE- some LVH
aortic regurgitation? - increased LVEDP
- increased LA pressure
- increased PCWP
- pulmonary congestion
