May support aortic pressure index for estimating AS severity when LV entry is infeasible; leaves open prospective validation before clinical use.
Does an index derived from the aortic pressure pulse correlate with calculated aortic valvular area in patients with pure aortic stenosis?
An index derived from the aortic pressure pulse provides a reliable estimate of aortic stenosis severity when the left ventricle cannot be entered.
Arani et al. (1967) studied this question.
