Abstract Objective: The most accurate noninvasive parameter to predict whether a patient
with aortic coarctation will meet interventional criteria at catheterization remains
elusive. We aim to determine the best independent echocardiographic predictors of
a coarctation peak‐to‐peak pressure gradient ≥20 mm Hg at catheterization, the ac‐
cepted threshold for intervention.
Design: Retrospective query of our catheterization database from 1/2007 to 7/2016
for the diagnostic code of aortic coarctation was performed. Multiple echocardio‐
graphic measurements and blood pressure gradients prior to cardiac catheterization
were collected. Univariate correlation of variables with the continuous catheteriza‐
tion peak were calculated using Spearman’s rho. Univariate association with… More >
