Excerpt

In their study titled “Clinical Utility of Doppler Echocardiography in Assessing Aortic Stenosis Severity and Predicting Need for Intervention in Children,” Vlahos et al. [20] embark upon a noble quest attempting to use Doppler echocardiographic data to predict the “grail” of catheterization-derived aortic stenosis gradient. They discover that the catheterization gradient is best predicted by an average of the two Doppler peak instantaneous gradients obtained from the apical five-chamber view and a high parasternal view. Furthermore, although the negative predictive value of a peak instantaneous gradient from the high parasternal view of ≤55 mmHg is perfect, receiver operator characteristic curve areas are only modest so that the decision to intervene in a child with valvar aortic stenosis based on a single Doppler measurement or site is only marginally helpful. …
