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.
