Which is not a feature of chronic aortic regurgitation



Choices

1 ) Decrescendo type early diastolic murmur is heard.
2 ) It is high pitched blowing murmur, heard best at left 3rd ICS
3 ) Narrow pulse pressure
4 ) Shorter the duration of murmur, severe the aortic regurgitation

Explanation


In chronic  Aortic regurgitation, there is a regurgitation of blood in diastole from the aorta into the left ventricle. This produces an early diastolic murmur. which is high pitched decrescendo best heart at left 3 and 4 ICS.

There is wide pulse pressure in aortic regurgitation. wider the pulse pressure more severe aortic regurgitation. 

More severe aortic regurgitation produces early equalization of pressure between aorta and left ventricle, thus early diastolic murmur of aortic regurgitation becomes shorter in duration.

Other signs of chronic regurgitation are enlarged left ventricle so the apex beat is shifted out and down. the apical impulse is a hyperdynamic type. bounding pulse

Peripheral sign of chronic aortic regurgitation 

Below signs are basically the manifestation of wide pulse pressure

1. Landolfi’s sign: Systolic contraction and diastolic dilation of the pupil

2. Shelly’s sign: Pulsation of the cervix

3. Becker’s sign: Visible pulsation of the retinal arterioles

4. De Musset’s sign: Bobbing of the head with each heartbeat (like a bird walking)

5. Corrigan’s pulse: A rapid and forceful distension of the arterial pulse with a quick collapse

6. Hill’s sign: Popliteal systolic blood pressure exceeding brachial systolic blood pressure by ≥ 60 mmHg (most sensitive sign for aortic regurgitation)

7. Gerhardt’s sign (aka Sailer’s sign): Pulsation of the spleen in the presence of splenomegaly

8. Duroziez’s sign: Gradual pressure over the femoral artery leads to a systolic and diastolic bruit

9. Traube’s sign: Systolic and diastolic sounds heard over the femoral artery (“pistol shots”)

10. Mayne’s sign: A decrease in diastolic blood pressure of 15 mmHg when the arm is held above the head (very non-specific)

11. Quincke’s sign: Capillary pulsations are seen on light compression of the nail bed

12. Muller’s sign: Visible pulsations of the uvula

13. Rosenbach’s sign: Hepatic pulsations
