Abstract
We investigated which physical parameter has the greatest impact on the perceived loudness of a systolic murmur in aortic stenosis. Loudness of murmur in aortic stenosis correlated best with peak momentum transfer--and thus with body size--so that loud murmurs predict severe disease less reliably in larger patients.
