Accuracy of quantitation of aortic stenosis using femoral arterial recordings corrected for both temporal delay and systolic amplification.
Our study demonstrates the feasibility of substituting FA recordings, corrected for both temporal delay and systolic amplification, for central aortic recordings in assessing aortic valve stenosis. This method is accurate in estimating the transaortic valve gradient, the calculated valve area, and the calculated valve resistance, and obviates the risks and costs of 2 FA punctures.
