Differential diagnosis | aortic regurgitation |
In cardiology, an Austin Flint murmur is a low-pitched rumbling heart murmur which is best heard at the cardiac apex.[1] It can be a mid-diastolic[2] or presystolic murmur.[3] It is associated with severe aortic regurgitation, although the role of this sign in clinical practice has been questioned.[4]
