A Cabot–Locke murmur〔Name That Murmur: Eponyms for the Astute Auscultician. Iris Ma and Lawrence M. Tierney. ''N Engl J Med'' 2010; 363:2164–2168〕 is an early diastolic heart murmur, occasionally heard in severe untreated anemia, without heart valve abnormalities.〔''The Journal of the American Medical Association''. 1903 Volume 40, Part 2 , 1539〕 It is detected infrequently, is best heard at the left sternal border, and sounds similar to aortic insufficiency, although it is without decrescendo. Its location, timing, association with severe anemia, and resolution upon correction of anemia, are consistent mechanistically with a functional murmur arising from high volume flow dynamics in the left main coronary artery, which has almost entirely diastolic flow. It is named for Richard Clarke Cabot and his colleague, Locke. They reported on a series of three patients who had been clinically diagnosed with heart valve disease, but who had normal valvular anatomy at subsequent autopsy. == References ==
