May reduce catheterization need for stenosis differentiation; hypothesis-generating and requires prospective validation before practice change.
Can arterial-sound recordings differentiate aortic-valve stenosis from subaortic muscular stenosis?
Arterial-sound recordings may offer a less invasive method to differentiate aortic-valve stenosis from subaortic muscular stenosis compared to cardiac catheterization.
Rodbard et al. (1965) studied this question.
