Interpreting measurements of cardiac function using vendor-independent speckle tracking echocardiography in children: a prospective blinded comparison with catheter-derived measurements

摘要

BackgroundAdult studies demonstrate that echocardiographic measurements of cardiac function using speckle tracking correlate with invasive measurements, but such data in the pediatric population are sparse. Our aim was to compare speckle-derived measures of cardiac function to measurements routinely obtained by cardiac catheterization in children.
