Aortic regurgitation

1. BY-SANGEETHA.C

2. Aortic valve composed of 3 cups- crescent
shaped, 3 sinuses & cups are sepreated
by 3 commisures and supported by a
fibrous annulus.
Behind each cups associated with sinus of
valsava.

9. AR is a condition due to inadequate
closure of the aortic valve leaflets leading
to abnormal retrograde flow of the blood
though the aortic valve during cardiac
diastole.
It can be induced either by damage to and
dysfunction of the aortic valve leaflets or
by distortion or dilation of the aortic root
and ascending aorta.

 IDOPATHIC AORTIC DILATION
 MYXOMATOUS DEGENERATION
 DISSECTION OF ASCENDING AORTA
 DILATED AORTA[ eg-S.HTN]
 AORTIC ROOT DILATION-marfan syndrome

11. Assess valvuLAR function
Identification of functional anatomy
Assess Lv size and function
Evidence of increased LVED- presystolic
[premature]closure of MV
 Presystolic [premature]opening of AV
LV chamber enlargement
LV function assessment

12. Diastolic fluttering of anterior MV leaflet
Reverse ‘ doming ‘ of the anterior MV
leaflet
Diastolic fluttering of AV
LEAFLETS: proplase of the valve leaflet
calcification of the leaflet
aortic root dilated
vegetation may be present in
the leaflets.

13.  IN acute AR- LV may be normal in size &
shape.
Increased LV diastolic
pressure
premature closure of the MV
can be seen due to rapidly increasing LV
pressure
 IN chronic AR- Ventricle develops eccentric
hypertrophy [ LV mass increased, wall
thickness increased , chamber dilated

51. It’s the surface area of the blood moving
back from the aorta towards the closed
aortic valve at the given aliasing velocity.
