Accuracy of matrix-array three-dimensional echocardiographic measurements of aortic root dilation and comparison with two-dimensional echocardiography in pediatric patients.

Background: Cardiac magnetic resonance imaging has demonstrated that the aortic root may be dilated in a dimension that two-dimensional echocardiography (2DE) is not able to interrogate. In the standard parasternal long-axis view, only a portion of the aortic root in the anteroposterior (AP) dimension can be visualized, as opposed to three-dimensional (3D) echocardiography (3DE), which can capture the entire root in an infinite number of planes. The purposes of the present study were to compare measurements of dilated aortic roots between 3DE and 2DE and to evaluate interobserver variability on 3DE.

What is the feasibility of imaging coronary arteries during routine echocardiograms in children?

Background: Abnormalities of coronary artery (CA) origins may be associated with sudden death. No data exist regarding the feasibility of routine echocardiographic imaging of CA in pediatrics.

Objective: Our aim was to determine the feasibility of imaging CA origins during routine echocardiograms.
