Assessments of Right Ventricular Volume and Function Using Three-Dimensional Echocardiography in Older Children and Adults With Congenital Heart Disease: Comparison With Cardiac Magnetic Resonance Imaging

Approximately half the patients with CHD had adequate three-dimensional echocardiographic images. Three-dimensional echocardiography accurately estimated EF but underestimated volume, particularly when the right ventricle was dilated. ABD minimally underestimated EF but offered a significant reduction in analysis time.
