Austin Flint murmur Information
Austin Flint murmur definition?
Austin Flint murmurs occur in aortic regurgitation due to the vibration of the anterior leaflet of the mitral valve as it is buffetted simultaneously by the blood jets from the left atrium and the aorta.An Austin Flint murmur is a mid-diastolic, low-pitched rumbling heard at the apex.
Onset, duration, and termination of the Austin Flint murmur are related to the amount of LV volume overload and the end-diastolic pressure in the LV chamber. In the most severe form of increased end-diastolic pressure, the murmur is heard in early to mid diastole.
