Austin Flint Murmur: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Aortic Regurgitation:
"The murmur typically begins in mid-diastole, often has a presystolic accentuation, and terminates at the end of diastole. It is low-pitched, with a rough and rumbling quality, and best heard at the apex. An Austin Flint murmur can be deemed present only in the setting of aortic regurgitation without coexisting mitral stenosis, since the latter can generate a similar murmur."

Sensitivity reported 25-100% in various studies. This source says that "specificity is irrelevant since Austin Flint murmur is by definition only found in AR".
