Describe the Austin flint murmur

1.    It is a low pitched rumbling MDM heard at the apex of heart.

2.    Heard with the bell of stethoscope.

3.    Patient lying in left lateral position.

4.    Austin flint murmur indicate severe AR.

5.    Usually associated with peripheral signs of AR.

6.    In mild to moderate MR no murmur is heard.

7.    In severe AR – mild diastolic murmur with presystolic accentuation is seen.

8.    In very severe AR – Only mild diastolic murmur without  presystolic component is heard.

9.    It is due to the premature mitral valve closure due to increased left ventricular end diastolic pressure.

What is the pathogenesis of Austin flint murmur

          It is produced due to the impact of regurgitant blood flow resulting in incomplete opening of the anterior mitral leaflet.

          Turbulence of blood flow is generated due to the mixing of the anterograde mitral flow with the retrograde flow through the aortic valve.

It is called as diastolic MR.

What are the named murmurs in cardiology?

Following are the named murmurs.

Still's Murmur

It is the innocent musical murmur ,seen in children.

Austin flint murmur

Mid diastolic murmur heard in apex in patients with aortic regurgitation.

Roger's murmur

It is the loud pansystolic murmur which is heard maximally at the left sternal border.  Heard in Ventricular septal defect (VSD).

Graham Steell murmur

Early diastolic murmur which is heard over Erb's point.Heard in pulmonic insufficiency, secondary to pulmonary hypertension and mitral stenosis.

Carey Coombs murmur

Mid diastolic murmur, heard in acute rheumatic valvulitis.

Rytands murmur 

Occur in complete heart block, this is a mid diastolic  murmur.

Docks murmur

This is a diastolic murmur, occur in left anterior descending (LAD) artery stenosis.

Mill wheel murmur 

Heard  due to air in right ventricular cavity following cardiac catheterization.

Cabot– Locke murmur

Diastolic murmur heard best at the left sternal border. heard in anemic patients .The murmur resolves with treatment of anemia.

Gibsons murmur

Continuous murmur heard in patent ductus arteriosis.Best heard at the left upper sternal border.

Key–Hodgkin Murmur

The Key–Hodgkin murmur is a diastolic murmur of aortic regurgitation .Hodgkin correlated this diastolic murmur with retroversion of the aortic valve leaflets ,seen  in syphilitic aortic regurgitation.
