Key result
2D echo accurately estimates RV volumes and RVEF compared to MRI in children.
Why the study?
Two-dimensional echocardiographic methods for right ventricular quantitation have been criticized as impractical and not reproducible, and a simple method introduced in 1984 was never validated clinically in pediatrics.
Does a two-dimensional echocardiographic method accurately assess right ventricular volume and function compared to MRI in children?
Observational
Does a two-dimensional echocardiographic method accurately assess right ventricular volume and function compared to MRI in children?
Effect estimate: r = 0.96 for diastolic volume, r = 0.97 for systolic volume, r = 0.90 for ejection fraction
A simple two-dimensional echocardiographic method using subcostal and apical imaging is feasible and accurate for assessing right ventricular volume and function in children, comparable to MRI.

Supports 2D echo for pediatric RV assessment; leaves open prospective validation before practice change.
Apfel et al. (1996) conducted an observational in Right ventricular volume and function assessment. Two-dimensional echocardiographic method incorporating subcostal and apical imaging vs. Magnetic resonance imaging was evaluated on Right ventricular diastolic volume, systolic volume, and ejection fraction (r = 0.96 for diastolic volume, r = 0.97 for systolic volume, r = 0.90 for ejection fraction). A two-dimensional echocardiographic method accurately estimated right ventricular diastolic volume (r=0.96), systolic volume (r=0.97), and ejection fraction (r=0.90) compared to MRI in children.
