pubmed:abstractText |
Characterization of the severity of a stenotic aortic valve relies on accurate measurement of the pressure drop across the valve. A simplified form of the Bernoulli equation has been used to estimate pressure drops using Doppler ultrasound, but these measurements often overestimate gold standard measurements performed during cardiac catheterization. Sources of discrepancy between the Doppler and catheter measurements have been identified, but no method has been developed to fully reconcile the two techniques.
