Austin Flint Murmur

American physician Austin Flint first described his namesake murmur in 1862.[1] In his own poetic words: "The murmur is oftener rough than soft. The roughness is often peculiar. It is a blubbering sound, resembling that produced by throwing the lips or the tongue into vibration with the breath of respiration." The murmur is best described in modern terms as a low-pitched mid to late diastolic rumble heard best at the apex of the heart and is associated with severe aortic regurgitation.
