Typically a feature of mitral stenosis (Fa---tah-tah-rrrrrrrrrr) but can also be one of the following three eponymous murmurs:
1. Carrey-Coombes
Acute rheumatic fever leads to thickening of the mitral valves and therefore give a middiastolic murmur. This is strictly speaking not a mitral stenosis (as there is no narrowing) and is thus called a Carrey-Coombes murmur.
2. Austin-Flint
In aortic incompetence, the pressure from the backlash of blood from the aorta prevents the mitral valve from opening and creates a functional block. This therefore gives a middiastolic murmur termed an Austin-Flint murmur, best heard over the left sternal edge.
3. Graham-Still
Similar to Austin-Flint, but problem resides in the right heart.
