Key–Hodgkin murmur: diastolic murmur of aortic regurgitation with a raspy quality, likened to the sound of ‘a saw cutting through wood‘.
Hodgkin correlated the murmur with retroversion of the aortic valve leaflets seen post mortem.
Hodgkin and Key were contemporaries working in London, at Guy’s Hospital. Key is credited with first drawing Hodgkin’s attention to the problem of aortic incompetence.
Hodgkin addressed this association in his open letters to Key which he read in February 1827 before the Hunterian Society
“My Dear friend. Thou will probably recollect having pointed out to me, a few months ago, a particular state of the valves of the aorta, which, by admitting of their falling back towards the ventricle, unfits them for the performance of their function“
